If you grow your own seedlings indoors under light , or if you buy transplantation from a nursery greenhouse , you will need to acclimate your seedlings before transfer them into the garden . This adjustment cognitive process is called “ Hardening Off . ” Here is how to harden off seedlings .
harden off is the appendage of accommodate flora to the outside , so they can get used to sunshine , breaking wind , rain , cool night , and less frequent lacrimation and fertilizing .

step by step increase the amount of clip that the seedlings spend outside to allow the plant to adjust . carry on to harden off seedling by moving the plants outdoors while temperatures are warm and then back inside at nighttime when the temperature is coolheaded .
I normally add a couple of hr each day as long as long the weather cooperates . modify the nuance or move the seedlings to a location that receive dawn or evening sun , so they are exposed to a little more sun each day . countenance the seedling to experience aristocratic piece of cake .

Warm - season crops such as tomatoes , peppers , Solanum melongena , melons , cucumbers , and some herbs prefer warm dark , at least 60 ° F . They ca n’t put up below - freezing temperature , even after the seedlings are harden off . So continue to bring indoors if night remain cool .

After your seedlings are inure off , they are quick to be transplanted into their lasting position in the garden .
take a nebulose day with no wind and transplant in the belated good afternoon or eventide to give your plants meter to adjust without the additional challenge of the Lord’s Day .
featherbed your newly planted seedlings frequently until they become established . You may see some wilting the first day , but plants should quickly perk up . And while some may adjust just ok and not require any special care , others may require auxiliary tearing .
Also supervise temperatures carefully ; unexpected temperature dips are rarified but do happen , and you may need to cover some plants to protect them .
