How To Plant Annuals

You can plant annuals in garden beds, containers, and even hanging baskets depending on the variety. Typically, you should plant them in the spring or summer. 

When planting annuals, dig a hole that is just slightly bigger than the root system of your plant. Then, carefully squeeze the plastic container and gently flip it over while cradling the annual with your hand. Never pull plants out of the containers they come in as this could break their stems.

Place the annual in the hole you dug and carefully cover it up with soil. After planting, water your annual. The type of annual you are growing will determine whether you should plant in full sun or partial shade. Water and care for your annuals according to the tag they come with.
