Do not plant in the garden until the danger of frost is past, or the soil temperature is 60 degrees. Indoor planting times are 6 to 8 weeks earlier than anticipated outdoor planting dates.
Buy short, stocky, dark green plants not yet in full bloom. Large plants in full bloom do not transplant as well as the smaller plants
During hot weather plant in the evening when it is cooler.
Most purchased plants are grown in containers with individual compartments for each plant. Remove plants by gently pushing on the sides and bottom of the compartment. Try to plant as soon as possible after purchasing. Plants allowed to sit around may be damaged by sun or dryness and may not recover.
Tear off the top of peat pots or bury them completely at planting time. If any of the peat pot sticks out of the soil it acts like a wick and dries out the rest of the pot. Roots have a difficult time getting through the dry, brittle peat.
Set plants at the same level they were growing at in the flat or container. Some individual plants have deeper planting depths suggested.
Once the plants have been set they need water.
Bleached leaves on newly planted transplants indicates insufficient hardening off.
What Are Annuals and Perennials?
Annuals complete their life cycle in one growing season. Seed germinates in the spring, the plant grows, flowers, produces seed and then dies.
Perennials live for more than one growing season. There are two types of perennials. Herbaceous perennials generally die to the ground at the end of the growing season but send up new shoots the following spring. Woody perennials, such as trees and shrubs, do not die back to the ground but get larger each year.
