Assorted PerennialsPlanting perennials requires extra care than planting annuals does. This is due to the nature of the plants themselves. Most flowering perennials will generally not bloom their first season, due to the necessity of strengthening the root system for the coming winter. When planting, many factors must be taking into consideration to ensure long plant life. The first factor to take into consideration is the location. Some perennials can withstand colder winters than others. To check which plants can survive in each region, you can look at the plant hardiness zone map. Sunlight and soil conditions must also be taken into consideration. Obtain this information before planting perennials in any location of the garden. Perennial GardenWhen planting perennials that are not yet mature, i.e. still in seed form, there are several options. Most nurseries will sell only plants that are already mature, but some gardeners prefer to mature the plants themselves. This can be done by initially growing the plant indoors in a pot or flat. When the plant has grown strong enough, usually six to eight weeks later, it should be transplanted to the final growing site in the garden. Another way is to plant the seed in late June in a shady nursery bed. Mulch should be applied to the plant in the fall to protect it through the long winter. In early spring, it should be transplanted to its final location.
