Ash Trees in the Urban Landscape

Trees with seeds and fruit have their benefits - and problems - that go along with them. Luckily, there are so many options available these days that it can be confusing when hearing all the various terminology that goes with plant options. So what’s the difference between all these new types of trees and shrubs? Botanical Terminology - Types of Plant Gender Monoecious  Dioecious Perfect Flowers  Sterile and Seedless Plants Other Oddities The Pros and Cons Perfect and Female Plants Pros and Cons of Male Trees Pros and Cons of Sterile/Seedless Plants Weighing Your Options Botanical Terminology - Types of Plant Gender In the world of plants - anything goes! Ma Nature regularly makes up rules, breaks them, remakes them, and then changes her mind once again. So plants have every possibility of reproduction available because of how ‘stuck’ in one place they are! So they of course had to get creative! Monoecious  Monoecious plants have separate male flowers and female flowers on the same plant. The term "monoecious" is literally "one house". Squash for example has male flowers and female flowers on the same plant. Dioecious These plants have male on one plant, and female flowers on another. Some Holly, Ash trees, Kentucky Coffeetrees, and Ginkgo trees are good examples. You need a male plant nearby to pollinate your female plants in order to see any fruit on the female plants. Perfect Flowers  Hermaphroditic flowers have both male and female structures within each individual flower, which are known as ‘perfect’. Each bloom can potentially pollinate itself without another flower. Bees or insects help distribute the pollen, and sometimes even wind. Perfect flowers can either be self-fertile or cross-pollinated. Cross-pollination needs another of the same plant nearby, or a slightly different variation of that plant. For instance, a Royal Ann Cherry Tree needs a Van, Stella, or a Black Tartarian Cherry tree nearby to pollinate it and set fruit. Bees are happy to visit both flowers and pollination occurs. Ma Nature's curveball - In a process called agamospermy, a plant egg can mature into a seed without being pollinated at all! The offspring is genetically identical to the parent plant. Sterile and Seedless Plants Sterile and seedless plants are hybrid cultivars that have been bred not to produce seed at all. This creates a triploid, like seedless watermelons and seedless grapes for instance. The genetics have been tweaked within these plants to make them entirely seedless or sterile. A normal diploid (like you and I) has two complete sets of chromosomes - one from each parent. White a triploid plant has three sets of chromosomes and retains many desirable characteristics, including increased vigor; larger flowers, or a larger fruit set. Then there are Triploids or Polyploidy, which as the name suggests, have three or more sets of chromosomes. Seedless watermelons are triploid which causes them to be seedless. These seeds are created by crossing a normal diploid as the pollinator with a tetraploid (Four sets of chromosomes) parent. Each parent contributes half its respective chromosomes, resulting in one from the diploid parent and two from the tetraploid parent. Sounds confusing but luckily the scientists have it all figured out and you don’t have to worry about seeds while munching on your favorite summertime fruit! Some plants and animals are bred (or have genetic abnormalities) and can become Polyploids that contain three, five, or some other odd number of chromosomes. A sterile perennial Geranium we love is Rozanne, which tries so hard to produce seed that it simply keeps on producing flowers all season long in that quest of trying to make seed. Other Oddities Then there are flowers like those on the Avocado tree which are perfect flowers, but they don’t function at the same time! The flowers are either male or female in the morning and then become the opposite later on or the next day. This means Avocado trees require a Type A and Type B tree planted in close proximity to increase pollination chances. The Giant Amazon Water Lily (Victoria amazonica) is another unusual perfect flower that has evolved a unique process of pollinating itself. Called co-sexual, the flowers open white in the evening, and are fragrant and warmer (called thermogenesis) than the surrounding male flowers. These close for the night trapping insects inside. In the morning, the flowers become female and open, and pollen gets distributed while the insect searches for a way out. Finally, the beetle is released to find another flower and gets trapped to start it all over again. Other plants can even change their sex based on the availability of other plants in the area, or based on their age and their height/sun availability. Lastly, plants like non-flowering Mosses, Liverworts, Hornworts, Lycophytes, and Ferns dispense with flowers entirely and reproduce by spores. The Pros and Cons There are always upsides and downsides to everything, and toying with the genetics of plants has come under scrutiny these days. Plausible, because everything in our environment does eventually affect us. So let's break down the pros and cons of all these types of plants! Perfect and Female Plants By planting trees, shrubs, and plants with perfect flowers, or a female plant with a male nearby, you then enjoy nuts, seeds, and fruit! When this comes to the perfect flowers of our favorite fruit trees like Grain, Nut trees, Apples, Pears, most Berries, and Grapes; having fruit is a great thing! Most of the world is fed on these wonderful plants! Fruit and seeds of these plants also feed birds and other wildlife. But these fruits do have seeds and those seeds do want to grow. Good if you are propagating and expanding your garden, but bad when those seeds come up everywhere and get into trouble. Like a mast year on Maples, or invasive plants like Purple Loosestrife. Especially if we don’t eat the fruit or seeds, like those winged Maple tree seeds, Elms, or Ash tree seeds, and Kentucky Coffee trees, or trees that produce tons of messy fruit like Mulberry trees. These fruits can spread themselves everywhere, come up where they shouldn’t, can clog drains and gutters, and sometimes become invasive. So that’s why having a male-only or seedless cultivar is preferred in today's urban landscapes. Pros and Cons of Male Trees Male-only trees solve the problem with fruit drop and seed dispersal. No fruit means clean driveways and patios, no stains on sidewalks and deck furniture, and you don’t have to worry about birds eating the fruit and spreading their droppings and those seeds far and wide. A sterile Walnut tree will give you the shade without the nuts staining pavement, and a male-only (or sterile) Maple will give you that fantastic fall color and shade without all the little helicopters that sprout up everywhere. The problem with male-only trees though, is that they still produce flowers - flowers chock full of pollen! Great for Bees and pollen-eating insects, but bad for our noses! Those who suffer from allergies are noticing an increase in their symptoms and increased frequency of pollen-related issues now that there are more male trees in the neighborhood! Pros and Cons of Sterile/Seedless Plants From an environmental aspect, having sterile plants reduces the chances of spreading invasive plants around where they are not native, and choking out local flora. Not necessarily meaning fruitless, it simply means the fruit won’t have viable seeds or any seeds at all. In fact, food harvest and fruit size can be increased in sterile plants. Plus, sterile plants can be shipped into areas where their seeded versions cannot due to invasive concerns. However, by planting these in areas they are not indigenous, and local pollinators and native insects often don’t recognize them as a food source. Good if you are trying to reduce pest damage, bad if you are trying to feed the bees, butterflies, and their larvae. Also having sterile plants means your feathered friends go hungry. Most of the issue with sterile plants that won’t produce fruit comes from those who think that changing the genetic structure of these plants (especially those we eat) will ultimately result in changes to our own DNA. While this may seem like woo-woo science, the increase in cancers, behavioral disorders, and the increase in general health issues around the world may just give you some new, literal, food for thought. The other concern is food sustainability and maintaining native plants and landscape cultivars. With reduced genetic diversity and the ability to save seeds for planting next year, having a landscape full of sterile plants leaves us hanging should they die. Entire crops can be taken out with no way of replacing them with their seeds. Some companies make their patented seed and plants with aptly named ‘Terminator’ genes so no one can replicate and grow their own plants and food without a tissue culture lab, or need expensive licensing and permission just to grow them. Weighing Your Options So there’s the good, the bad, and the ugly side to plant gender and how it affects us and our environment. There are benefits and worries to all sides of bringing new and exciting plants to every corner and environment in the US.  So take a look at your options and see what is available before making a decision when landscaping. Alternatives are increasingly easier to find! Look into more careful site selection and your personal needs when choosing plants for your landscape!

Yellow or orange flowering or foliage plants add a stunning sizzle and ensure visual highlights to any garden or patio! The opposite of purple and blue on the color wheel and melding beautifully with the green of most plants. The Science Behind Yellow & Orange Color The dominant wavelength of light in the human eye, yellow and orange are frequent colors found in nature. The Lascaux cave in France has a painting of a yellow horse 17,000 years old because Yellow is so easily available in nature, so it’s no wonder why ochre pigment was one of the first colors used in art. Yellow and orange absorb the sun's light energy and protect plants from photodamage and embody natural light and warmth.

First, always make sure to read the care instructions found on the Nature Hills Product Pages. This will let you know how much sun, water and what type of soil a plant needs to thrive. Then find your growing zone here to get started! Perennials do best in well-drained enriched soils and need regular fertility. Water new plants regularly until they are established during their first year. During the hottest months of the year, you’ll want to take extra care to make sure your perennials are getting enough water. One of the best things you can do for your flower gardens is to add a 3 to 4-inch layer of arborist mulch chips around the plants. This helps conserve water and protects the roots from the heat in the summer and the cold in the winter. Most perennials are herbaceous perennials, meaning they will die back to the ground and should be pruned in late fall when they do die back. A few exceptions prefer pruned in early spring. All appreciate some deadheading right after their flowers bloom for a cleaner effect and often to encourage a rebloom later in the growing season! You’ll find each plant's pruning needs on each plant description page. Easy Warmth & Brilliant Color With Yellow & Orange Plants! Yellow flowering perennials can represent the return of spring while orange can harken to the start of summer and autumn! Combine both and you have a delightfully exotic combination! Brighten, excite, and invigorate your garden today! Browse the huge selection of yellow and orange perennial flowers for sale at Nature Hills Nursery, and reserve your plants today! Happy Planting!

Many types of today's fruiting and flowering trees and shrubs have been grafted. As are many Shade and Ornamental trees, Evergreens, some Grapes, and some Roses are grafted onto rootstock. Why are so many plants grafted, what are the benefits, and what exactly is rootstock? Why Are Trees and Shrubs Grafted? Benefits of Grafting: What Are They Grafted Onto? What Is The Rootstock Or Understock? Types of Grafting Grafting Examples Other Types of Grafted Plants Planting and Care of Grafted Trees & Shrubs Fantastic Grafted Trees Why Are Trees and Shrubs Grafted? Specific cultivars of our favorite trees and shrubs are grafted as either a single bud or as a scion, onto a compatible root system so they can successfully be cloned. Grafting a new root system, called the rootstock, is done so there is perfect consistency across the board. Unlike seeds and plants on their own roots -where there is often quite a bit of variety in flower color, size, shape, resistances, life span, fruiting vigor, or fruit quality/quantity. Grafted plants have so many incredible qualities you may not even realize! Benefits of Grafting: Grafted plants mature plant faster and in some cases flower and fruit earlier Propagate by cloning uniform crops of specific cultivars at the nursery Perfectly recreating certain benefits and resistances consistently  Improved resistance, fruit, flowers, drought tolerance & cold hardiness Ensuring virus-free material and virus-resistant rootstock Dwarf, Semi-dwarf & compact varieties Larger flowers or fruit Grafted trees may produce fruit at an earlier age Some plants are difficult to root or grow from seed but readily propagate via grafting More variety in a larger climate range Increased Vigor Grafting takes the benefits of one plant and fuses them onto the roots of another plant that’s closely related. The cons of grafting are only the lingering stigma these plants carry as being ‘weaker’ and breaking easily, and the lingering fear of contaminated source material - which these days is no longer the case! What Are They Grafted Onto? Like us when receiving a blood transfusion or organ transplant - it has to be a compatible match! So, Cherry tree cultivars must be grafted onto Cherry tree rootstock, Oranges to Citrus, Roses to Roses, and Apples to Apples. This process allows growers to cherry-pick specific traits and qualities from both the root and the bud while maintaining consistency throughout an entire crop. Simultaneously removing problems or negative traits that some varieties may carry and preventing them from passing on undesirable traits like thorns, or bitterness. What Is The Rootstock Or Understock? It all starts with quality rootstock, also known as understock, which is simply the roots of the plant chosen for the specific traits and qualities the source tree has. Once joined, these traits are then passed onto the grafted, above-ground portion we see - called the scion (a small branch), or it can be just a single bud! This allows many grafted plants to be created from a small amount of source material. There are many types of rootstock available and rootstocks used may change by the region where the plants are being produced for (increased disease resistance or better tolerances for that region). Sometimes they are changed based simply on availability for that particular year. A few plants need something called an Interstock which is like a go-between that joins the scion and the rootstock. A few tree Roses have interstocks (one for the roots, another for the trunk, and then top grafted rose selection on top) that help plants that may not be completely compatible with each other to be solidly joined together and grow stronger. Like rootstocks, interstocks can impart further benefits to both the rootstock and scions alike. Once grafted together, the graft union grows to be less obvious over time and the two parts seamlessly become one. Modern cultivars and grafted plants won’t come true from seed and can be propagated by way of grafting to ensure you are getting the exact same plant every time. These specific cultivars (the combining of the words - cultivated and variety) have to be grafted or rooted. Many tree cultivars and fruits will not be able to be rooted on their own, so they must be grafted. Once the living portion of the plant tissue, called the cambium layer (which is just under the bark) from the bud or scion is aligned with its rootstock, the roots begin pushing nutrients and plant hormones into the graft to heal the wound and fuse the two together and make them both grow. Types of Grafting Grafting can be traced back 4,000 years to ancient China and Mesopotamia! Today's modern nursery experts employ a wide variety of propagation techniques depending on the desired outcome and type of source material they are using.  While most fruit trees are grafted using a T-Budding graft, other types of grafting include cleft, side-veneer, bark, chip, bridge, saddle, inarch, whip and tongue, and splice grafting. Grafting Examples Let’s say you want to grow a Honeycrisp Apple tree. You can’t just plant a seed from a Honeycrisp Apple as it will not have the same traits or DNA when it is grown from seed, and you might get one of its parent plants from the past. The same goes for a Bartlett Pear, a Bing Cherry, or other selected varieties of fruiting and flowering plants. Standard trees (native, ‘own-root’, or heirloom varieties) all can grow very large - sometimes 20-50 feet large! But they can also benefit from being grafted onto rootstock. Some understock used to grow standard-sized Apples for example include Domestic Apple seedlings, Antonovka, or M25. Rootstock can precisely change the ultimate mature size of the tree. With the Honeycrisp Apple for instance - A Honeycrisp is a Honeycrisp no matter which rootstock it is grafted onto - but different rootstocks can alter just how big that Honeycrisp will ultimately get. True Dwarf Apple varieties are typically grafted onto a dwarfing rootstock, maturing at only about 40 percent of the normal size of a Standard Apple. Although the plant stays small, the fruit is the normal size. Note true Dwarf Apple trees will need staking to prevent them from blowing over in the wind as they can’t support the weight of the fruit well with this rootstock. Dwarf fruit trees are used for small spaces and to make harvest easier and typically get 6 - 12 feet tall. Commonly used Dwarf Apple rootstocks are Bud 9, G.11, G.65, G.41, G.214, and M9-337 Semi-Dwarf trees are a great size if you have a bit more space in your landscape and more than double the harvest of true dwarf plants. Semi-Dwarf Apple rootstock keeps the plants in the 12-20 foot range and prevents them from growing taller for easier to harvest. Semi-dwarf Apple rootstocks may include EMLA 9, EMLA26, G.30, G.890, G.202, G.935, M7, MM106, and sometimes MM111. Other Types of Grafted Plants A Rose Tree-Form can be created by combining a straight Rose stem called the ‘standard’, a rootstock, and a specific variety of Rose shrub together. Creating a topiary or ‘Lollypop’ tree. Many types of Lilac Tree-forms and flowering Cherry trees are also grafted. Other types of grafted examples are combination trees where multiple types of a tree are grafted together to create unique specimens that can have multiple varieties of fruit like the Espalier Edible Grafted 6-In-One Apple Tree that has 6 fantastic varieties on one trunk! Grafting on larger more mature trees can also be done to repair damage from physical damage. Like a surgeon replacing a lost limb or organ, tree surgeons and arborists can just attach a new branch where one was lost due to storms or accidents! Planting and Care of Grafted Trees & Shrubs The graft union should be planted just above ground, and never plant any roots too deep, or too shallow. Look for the root flare, the widest part of the stem just above the root, and find where it either slightly angles away before growing straight again, or bulges at or around ground level. You’ll notice a difference in bark color or texture where the roots and scion meet, identifying the graft joint. Dig your hole about twice as wide, but the same depth as the current root system Situate the roots so the graft is just above the ground and the root flare is at ground level Backfill with native soil and tamp down gently Water your new plant in very well saturating the soil completely at planting Add a 3-4 inch thick layer of mulch over the entire root system Pull the mulch away from touching the trunk and graft union. Maintain consistent moisture for the first year of the plant's life by checking using the ‘Finger Test’ and checking the soil moisture every day, adding water when needed until the plant is established. That’s it! Fantastic Grafted Trees Don’t be leery of grafted trees and shrubs! Grafting or budding is not a bad thing, but a necessary way to propagate many of our favorite trees! They are stronger than you think because of the combined union of two fantastic plant portions, both working together to amplify everything you love about your new plant pet! There is nothing you need to do beyond water and the same support you’d give to a non-grafted plant, but you will reap all the benefits these fantastic plants offer! It is a good idea to protect the trunks of all young trees from rodents and deer rubbing during the winter months. Check out all the different grafted and ‘own root’ varieties available at Nature Hills today and get the landscape of your dreams! Happy Planting!

Savory briny Olives are a favorite snack and topping for many around the world! But did you know you can grow your own olives? Since ancient times, Olive trees (Olea) have been a staple in the Mediterranean landscape and diet. Capture the essence of sun-drenched coastlines and connect to a sense of antiquity with Olive trees from Nature Hills Nursery. Not just a fantastic specimen, shade, and landscape tree, Olive trees are a long-lived cash crop and specimen plant for many around the world and right here in the US! All About Olive Trees History & Symbolism of Olive Trees Nutrition and Health Benefits Where to Plant Olive Trees Where Olive trees grow best Maintenance Pruning & Thinning Olive Trees in Containers Harvesting Olives Preserving Olives Outstanding Olives! All About Olive Trees Creamy white blooms appear in sprays all over the tree, sometimes in such quantities, the tree will look frosted! Beloved for their wonderful fragrance, they are nestled among the tree's dark green leaves, but your pollinators will find them in swarms! These flowers are also wind-pollinated, further increasing pollination chances. Flowering is induced by fluctuation between day and nighttime temperatures, as well as two months of temperatures below 50°F for flower initiation. While mostly self-fertile, having multiples of the same Olive tree, or planting a Pendolino Olive as a universal pollinator, you’ll enjoy a far larger harvest per tree. The Olive fruits themselves are considered botanically drupes, or stone fruits like Peaches, in fact, they’re closely related! Other close relatives are Cherries, Almonds, and Pistachios. The exotic sage-green to gray-green foliage makes these fantastic specimen trees and airy shade trees! Adding a wonderful Mediterranean aesthetic to your landscaping, Olive leaves offer a soft and subtle fine texture while the leathery broad-leaved evergreen foliage suits even the smallest properties! The most unique characteristic of this tree is its slower-growing nature, creating a gnarled, twisted trunk. Over time, this tree adds character and a sense of antiquity to your landscape! The wood is decay resistant and even recovers after fires. Want a faster-growing Olive tree? Try the Frantoio Olive Tree, which is also one of the few that can tolerate down to zone 7 climates! There are 139 Olive varieties and each olive cultivar has its own unique chemical and taste characteristics. Living for 300-600 years, the oldest Olive tree in Greece is 2,000 years old and still produces fruit! Performing best and living the longest in Xeric, arid, and Mediterranean climates, but also doing well in any tropical to temperate area with adequate drainage. Fruit Ripens From Green to Purple to Black With 1-2 Seeds Self-Pollinating - Prolific Harvest Fragrant Creamy White Blooms Shade, Specimen & Container Plants Great for Edible Landscaping Grey-Green Silvery Broad-Leaf Evergreen Foliage Slow to Fast-Growing Varieties Unique Twisting Trunks History & Symbolism of Olive Trees There is fossil evidence that wild Olive trees appeared in the area around the Mediterranean Sea millions of years ago. As far back as the Bronze Age, humans have relied on Olives for food. That long historic relationship gave rise to symbolic meanings linked to the tree and its versatile fruit. An Olive branch is a universal symbol of peace. Greeks and Romans crowned victors of war or competition with crowns of Olive garlands, and Olive Oil is an important element in many religious ceremonies. Spanish explorers introduced Olive trees to the New World in the 1500s and to California in the 1700s. Today, these Fruit Trees are cultivated throughout the tropical regions of the world. Nutrition and Health Benefits Olives contain 11 - 15% fat, and 3/4th of that fat is oleic acid, a type of monounsaturated fatty acid. They are also low carb and high in Vitamin E. Olives are also a fantastic source of Iron and Copper. Olives are rich in polyphenols which have antioxidant properties. The beneficial effects of these compounds include reducing the risk of chronic diseases such as atherosclerosis and cancer. These healthy snacks and frequent charcuterie board additions are only around 60 calories for 10 Olives! Where to Plant Olive Trees The highly adaptable Olive variety does well in the ground and in containers, making it easy to keep one near the kitchen for your culinary masterpieces! Olive trees do well in sunny areas and will be happy in soil with excellent drainage.  They’re easy to grow and are resistant to most insects and disease issues. Olive tree varieties are tolerant of drought and brief chill. Olive trees grow best in planting zones with hot, dry summers and mild but cool winters that never freeze. Just avoid planting one near a patio, driveway, or sidewalk as the dropping fruit can be a bit messy.  But you won’t have to worry about birds eating your harvest, because of the saltiness and bitterness of fresh olives, your feathered friends won’t eat your crop. Squirrels however may eat the seeds, but they prefer other nuts and seeds over Olive pits. Unless you have cattle, sheep, goats, and camels, there’s no reason to chase wildlife out of your tree! Where Olive trees grow best Full sun - Minimum 6 hours of direct sunlight a day Low moisture needs & moderate fertility once established Can prune smaller for use as an ornamental container tree Pest & disease resistant Loves heat! - USDA zones 8 - 10 outdoors (Frantoio Zone 7) Drought tolerant & thrives in coastal conditions Highly adaptable! Are Olive trees high maintenance? Not at all! Olive Trees are ideal for the home grower because they are small and hardy, and require very little maintenance to turn out a bumper crop of olives. Outdoors, the Olive is adaptable to a variety of conditions, even doing well in poor soils or drought once established! What is the easiest Olive tree to grow? The Arbequina Olive Tree is regarded as one of the easiest to grow and is often used for patio containers and produces high-quality Olives around November. Arbequina is also one of the most popular Olives at NatureHills.com! Maintenance Pruning & Thinning If you decide to shape or control the size of your Olive tree, they are amenable to pruning. Needing regular pruning to maintain vigor and increase fruit production, prune after fruiting for best results. It’s best to prune established trees for shape and to keep them from growing too large. Keep an open canopy and remove weaker and less productive branches. Olive flowers in the shade will not set well, so ensure sunlight can penetrate the entire tree canopy. Thin fruit by removing excess fruit, keeping three or four fruit per foot of twig as soon as possible after the fruit set. This increases the size of the fruit you leave on the tree. Olive Trees in Containers For colder climates, plant a Mission or Leccino Olive tree in a container. Bringing fruit trees indoors for the winter protects the plant and lengthens your enjoyment of your Olive tree. Try these Olive tree varieties in containers with adequate drainage. Olive trees grown indoors do not set fruit, but they are lovely ornamentals to decorate your interiorscape when enough bright light is available. Harvesting Olives How many years does it take for an Olive tree to bear fruit? Olives can start producing fruit after 3-5 years of age and Nature Hills ships trees at least 2-3 years old already! Some Olives can produce small to large crops annually, while others are biennial bearing, while others yet have a decent crop one year and then a light one the next. But a mature tree can produce over 200 lbs (100kg) of fruit! The Olive fruits are botanically drupes, similar to the Peach or Plum. An Olive begins as a green fruit that makes a slow transition to purple before turning black, indicating it's time for harvesting. This happens sometime in late November til January. What’s the difference between green and black Olives? Other than the color, green Olives are saltier, tangier, and can be a bit more bitter, while black Olives have more oil and less salt. You can change the ultimate flavor by how you preserve them. They're just perfect for snacking, adding to drinks, and slicing for use as a topping on pizza. Olives also produce high-quality oil for culinary uses and cooking, beauty and health care, and religious purposes. Olives can be harvested while unripe and green, or when ripe and fully black Harvest for oil when the fruit is black on the outside, but the inside is still green/yellow Pick gently to avoid bruising if used for brining You can knock them out of the tree with a pole when harvesting for oil Olives must be cured before they can be eaten. Once cured they are great table fruit Preserve in water, oil, brine, salt, or lye to remove the bitterness and preserve them Preserving Olives Curing and preserving methods range from curing your Olives in caustic soda, in a salt/water brine, or in a vinegar and oil mixture. Make sure your containers and utensils are clean and sterile, and made from non-reactive materials (avoid copper, brass, iron, or galvanized pots/utensils). Once canned, the Olives will be ready to eat in 3-6 weeks depending on the variety, how much oil is in the Olive, their size, and the method of preservation. Outstanding Olives!

Tropical greenery and live exotic plants add a verdant and unique texture and form to your home and outdoor rooms. If you are lucky to live in a warm climate that’s frost-free, decorate your landscape year-round! Often originating from rainforests, native to exotic locations around the world, some can even be grown right here in the US! Thriving in the consistent temperatures and higher moisture availability these frost-free growing zones provide. Temperate regions without a cold winter allow for more vigorous, lush growth and the year-round growing conditions give these plants the time and nutrition to grow bigger leaves, faster growth, and more varied forms! It’s those unique forms and curious features that are so enticing to us! We’re drawn to these differences and to these plants' ease of care and adaptability in our homes and on our porches, patios, and summertime outdoor living areas! Tropical Plant Care Thriving in the heat, soaking up humidity, and appreciating deeper organic soils, enriched containers, and, for the most part, loving soil moisture, tropical plants are surprisingly low maintenance and easy to care for!  Sun Most Tropicals are understory plants, living in the shade and dappled shadow of larger more established plants and trees. Others live in the dappled part sun or even full shade! For most houseplants and indoor tropical plants, bright but indirect sunlight is their favored location! Few like full sun indoors because windows seem to focus the light and can sunburn the leaves, causing them to bleach out or fade.  Low-light plants tolerate indirect light from not just a low-light window or fluorescent lighting from an office space or LED or incandescent grow light from a bathroom or bedroom lamp. Read on our Plant Highlights section on each plant's page for what kind of lighting your chosen plant needs to be happy and healthy! Pothos and Philodendrons are natural in lower-light areas and won’t mind anything except full shade. Bright Indirect Light Indoors Supplemental Light (Grow Lights) If Not Enough Sun Part Sun/Part Shade - Favoring Afternoon Shade Outdoors Full Shade or All Day Dappled Shade Outdoors in Hot Climates For locations indoors that do not have big bright windows and sunrooms, there are always supplemental grow lights available to extend your light amounts, especially in the winter months when there’s less sun availability in general. Soil Requirements & Fertility Tropicals need enriched, highly organic, and moisture-holding (but not soggy) soil. Preferring slightly acidic conditions best. Be sure the location or container of your plant (most plants for that matter) are in well-drained soil and have a way for excess water to drain out and away from the roots. Standing water is rarely tolerated and will cause your plant to die.  In their understory native environments, there is a high availability of leaf litter and composted soil from the larger trees and shrubs they grow among, so recreate that setting by using lots of compost and organic matter for them to grow in. These types of soils also have higher moisture absorption and moisture content.  Enriched Highly Organic Soil Compost, Peat Moss Needs Good Drainage Slightly Acidic Regular Fertility Furthermore, Tropical Plants may need a half rate of fertilizer quarterly - unless you are in the more northern regions where winter days are short and cloudy. If this is the case, you might want to skip the 4th quarter application (October through December). Air Humidity & Moisture Needs While many prefer higher moisture and consistent watering, they do poorly in soggy soil and quickly succumb to root rot. For in-ground plants in warm climates, regular watering in the heat of summer, and throughout the drier parts of the winter are necessary to maintain a healthy root system. There are some exceptions like the Snake Plant (Sansevieria), Cactus, and Succulents that prefer lower moisture conditions once they're established. Because of their contained environment, container plants need frequent water checks as the water needs will change depending on the pot size and the climate they are being grown in. Once the surface of the soil is dry to the touch, it is recommended to water thoroughly, let the excess drain out the bottom, and discard it. This will greatly vary throughout the year and the interior environment of your home. In winter time it is recommended to increase air humidity with a humidifier, but back off on how much water you add to the soil. Even though some tropicals may have a dormant period, they do back off on growth and flowering in the lower light levels of the winter months. Moderately Yet Consistent Moisture Regular Water Checks for Container Plants Good Drainage Higher Air Humidity Reduce Watering in Winter (Indoors) Water Outdoor Plants in Heat, Drought & As Needed in Winter Drier office locations and air conditioners that remove air moisture might make us more comfortable, but they reduce the available humidity that these plants thrive in. Setting your plant's pot in a tray of pebbles that are filled with water (ensuring the water does not touch the bottom of the pot) will help increase the relative air humidity around the plant itself, a humidifier or frequent misting help too!  Temperatures The constant temperatures of many of these unique plants' native environments aren't just throughout the year, but also have less of a drop in temperature between day and night! Most houseplants and exotic plants prefer an average relative temperature between 65-75°F. Any temperature dropping below 50°F can spell certain doom! Gradually transition them indoors in anticipation of cooler temperatures so there is not a shock to their system. Keep your Tropicals away from drafts and dry air vents and heaters in the winter, while keeping them out of the brunt of the full sun in the summers. Container plants on porches will need to be watched, moved, or shaded from the hottest days - especially if they’re not acclimated to the bright sunlight after months of being indoors. Tropical Plants & Changes in Environment No one likes drastic change! Your plants are the same way. Remember to always slowly transition your indoor houseplants to the outdoors so they can acclimate (get used to) the higher sun intensity and longer daylight hours. This prevents leaves from blanching in the sun and even cooking in the direct light. Keeping their environment steady also reduces leaf drop which is a frequent result of stress. Likewise in the autumn, when there’s a threat of frost for Northern growing zones, gradually reacclimate your plants to the indoor environment over the weeks before an expected start of the chilly weather to prevent leaf yellowing and leaf drop, like Ficus, Gardenia and some other types of plants. These plants often have a temporary ‘freak out’ when they’ve been moved to a new location inside the home, or transition inside and out (or vice versa) and take a bit of time to adjust to their new surroundings - resulting in leaf drop.  While distressing to witness, just let your plant adjust and maintain as much consistency as they settle. It’s a knee-jerk reaction to add fertilizer in these times of temporary crisis - but don’t! Forcing a plant extra nutrition that stimulates growth, when it's already stressed, will just cause more stress! Tropical Plants in Containers and Planters Because of their love of consistent temperatures and moisture, Tropical plants are perfect for the home environment and in the container gardening landscape! Because you have higher control over what goes into the soil in a pot, you are also better able to control the moisture and fertility too!  As with any plant in a contained environment, poor drainage is the main killer of any plant bound to a pot. So add drainage holes and always check before watering, adding a tray under the pot to catch any dribbles and excess water. If your container plant dries out frequently, it might be time to shift your plant to a larger size pot. Knock the plant out of the pot and look at the roots. If there is a mass of roots with little soil between them, it is time. Don’t cover the new pot’s drainage hole, or use gravel at the bottom. This can slow drainage and speed up occurrences of root rot. If you’re concerned about soil seeping from the container bottom, cover the hole with a folded paper towel or coffee filter. Add some potting soil to the new container. Spread the plant roots, placing them on the soil. Make sure it’s centered and upright. Fill with soil and water well to settle in. Fertilize at least three times a year during the growing season, avoiding fertilizer in the winter while these plants take a break from growth in the cooler growing zones. If you are in a warmer climate with mild winters, a fourth mild dose of fertilizer will keep your plants healthy in the off-season.  Types of Tropical Plants at Nature Hills!
