Harden Seedlings

Tip description

A garden cart lets you move the seedlings around easily, by Kristine Lang, South Dakota State
Seedlings grown indoors or in a greenhouse are tender because they have been sheltered from direct sun and outdoor conditions. You need to acclimate them to the great outdoors, a process called hardening, before planting them into the garden. Start by giving them short exposures to full sun and cool nights, gradually increasing the amount of time. Seedlings can dry out quickly, so be sure to keep them watered, especially with hot or windy weather. Protect them if nights are cold. After about two weeks, they should be ready to start life in the garden.
