Transplanting Seedlings
Technique
Transplanting seedlings moves young plants from flats, pots, or protected spaces into larger containers or garden beds. Careful handling helps seedlings establish quickly and continue growing with minimal setback.
How to do it
Water seedlings before transplanting so the root ball holds together and roots are less stressed. Handle plants by their leaves or root ball rather than by delicate stems, and set them into prepared soil at the proper depth for the crop. Firm the soil gently around the roots and water after planting to settle the soil. Provide temporary shade or wind protection if conditions are harsh during the first few days.
Timing
Transplant after seedlings have developed enough roots and leaves to handle the move, and after hardening off if they were grown indoors. Warm-season crops should usually go out after the last spring frost, while cool-season crops may be planted earlier if conditions are suitable. Choose a mild, cloudy day when possible to reduce stress.
Tips
Do not leave seedlings root-bound for too long in small cells. Match spacing to the mature size of the plant so air circulation and growth are not limited. Watch closely after transplanting and water as needed while plants establish.
