Planting & Care

Where to Plant

Sunlight: This shrub thrives in full sun, requiring at least six to eight hours of direct light daily. While it can tolerate light shade, you will notice fewer of the signature yellow pea-like blooms and a less dense weeping habit if it lacks sufficient sun.
Soil: It is remarkably adaptable but prefers well-drained soil. If you are dealing with heavy clay, mix in some organic compost to improve drainage, or plant it in a slight mound to keep the roots from sitting in "wet feet," which can cause root rot.

Watering Requirements

For the first year, water your tree twice a week to ensure the root system establishes deeply. Once mature, the Weeping Siberian Pea Shrub is exceptionally drought-tolerant, but providing a deep soak during extreme summer heat prevents the foliage from yellowing or dropping early. Inconsistent watering during the heat of July can lead to smaller leaf size and a generally stressed appearance.

Pruning Tips

Since this tree is grafted onto a standard trunk, you should prune in late spring immediately after the flowers have faded. This plant blooms on old wood, so pruning too early in the spring will remove the season's flowers. Focus on thinning out the interior "nest" of branches to improve airflow and trim the trailing stems if they begin to touch the ground to maintain a clean, umbrella-like silhouette.

Fertilizer Needs

Apply a balanced, slow-release fertilizer in early spring just as new growth begins to emerge. Avoid using high-nitrogen fertilizers late in the summer because this encourages tender new growth that won't have time to harden off before the first frost. This late-season growth is easily damaged by winter temperatures, which can lead to dieback at the tips of your weeping branches.

Understanding Our Container Sizes

At Nature Hills, our plants are sold in industry-standard nursery containers. You will notice we use the word "container" rather than "gallon." Container numbers follow a nursery trade size standard, not liquid volume. The number tells you the plant's size category and general maturity level. A larger container means a more established plant with a stronger root system.

Container Sizes

Quart

Plant age: 6 months to 1 year
Best for: Ground covers, perennials, ornamental grasses
What to expect: Our smallest and most affordable size. Well-suited for planting in multiples across a large area. Allow 1 to 2 seasons for full establishment.

#1 Container

Plant age: 1 to 2 years
Best for: Shrubs, perennials, smaller trees
What to expect: About the size of a large coffee can. A well-developed root system in a manageable size. Good value choice when you have time to let the plant grow into the space over a season or two.

#2 Container

Plant age: 2 to 3 years
Best for: Shrubs and trees where you want faster establishment
What to expect: A noticeable step up from a #1 in both plant size and root development. Good choice when you want visible presence without going to a larger size.

#3 Container

Plant age: 3 to 4 years
Best for: Most plants, most situations — flowering trees, shade trees, evergreen shrubs
What to expect: Our most popular size. Strong, developed root system. Plants in a #3 container make an immediate visual impact from day one. If you want a head start rather than waiting seasons for a plant to fill in, this is typically the right choice.

#5 Container and Larger

Plant age: 4 to 5+ years
Best for: Specimen plants, privacy screens, maximum instant impact
What to expect: Large, mature plants ready to make an immediate statement in your landscape. We also carry #7 and larger sizes for select varieties.

Why "Container" and Not "Gallon"?

Nursery container sizes follow an industry trade standard established for the nursery and horticulture industry. The number is a size designation, not a measurement of liquid volume. Actual soil volume varies by plant type, root mass, and growing medium. Using "container" is the accurate industry term. When you see #1, #2, or #3, think of it as the plant's size tier, not a gallon measurement.

Root Pouch Containers

Some Nature Hills plants arrive in a Root Pouch, a breathable fabric container made from 100% recycled materials. Root Pouches encourage denser root development through air pruning, which discourages root circling and promotes a stronger, more fibrous root ball at the time of planting.

There are two types. Knowing which one you have changes how you plant:

Degradable (brown or tan fabric): Plant the entire pouch directly in the ground. The fabric breaks down naturally in the soil over time.
Non-degradable (black or gray fabric): Remove the pouch before planting. Cut the bottom open with scissors, then peel the sides away. The fibrous root ball will hold its shape.

If you are looking for a high-impact architectural specimen that laughs at sub-zero temperatures, the Weeping Siberian Pea Shrub Tree Form (Caragana arborescens 'Pendula') is a masterclass in landscape versatility. Often referred to as the Weeping Caragana, this grafted standard is a "living waterfall" that brings dramatic vertical interest to even the smallest garden plots.

A Cascading Masterpiece of Texture and Color

The standout feature of this specimen is its weeping habit. Slender branches arch gracefully from the top of a sturdy trunk, draped in bright green, pinnately compound foliage that looks remarkably like a fine-textured fern. In late spring, the canopy is punctuated by clusters of cheery, bright yellow, pea-like flowers. These blooms are not just for show; they are rich in nectar and serve as an early-season magnet for pollinators. As the season transitions into fall, the foliage may take on a yellow hue before dropping to reveal the intricate, architectural branching structure that provides winter interest against the snow.

Siberian Toughness for Modern Landscapes

Don't let its delicate, weeping appearance fool you. True to its name, Caragana arborescens originated in the harsh climates of Siberia and Mongolia. This heritage makes it one of the most rugged ornamental trees available. It is exceptionally cold-hardy and possesses a rare tolerance for alkaline soils, high salt spray, and drying winds. Because it is a member of the Fabaceae (legume) family, it is also a nitrogen-fixing plant, meaning it can actually improve the soil quality where it is planted.

Versatile Landscape Applications

Because it is grown in a "Tree Form"—meaning the weeping variety is grafted onto a straight trunk (standard)—it maintains a predictable height. This makes it an ideal choice for framing an entryway, adding height to a perennial border, or serving as a sophisticated focal point in a large patio container. It’s a perfect solution for "hell strips" or coastal gardens where poor soil and wind often discourage more sensitive species.
