If you are asking about vegetable plants (you did not specify) then:
Hardening off the plants: Whether you have purchased transplants or raised them yourself, they should be transplanted out into the garden as soon as the danger of frost is passed. Allow a short transition period (also known as hardening off) outdoors for seven to 10 days before planting. Set the transplants in a shady location protected from sun and wind to help them adjust to their new outdoor environment. Gradually expose transplants to longer periods of sun and wind. Keep the transplants’ soil moist during this transition period.
