Vegetable transplants are commonly grown in New England in greenhouses for field transplanting or spring sales at farm market stands. Many vegetable crops are grown from transplants in New England due to the late spring, short growing season and desire to obtain mature, harvestable crops as soon as possible.
Transplant production is a specialized part of vegetable production that requires a protected environment such as a greenhouse and careful attention to detail. Although vegetable bedding plants may only be in the greenhouse for a short period of time, it is important to produce high quality pest-free transplants. Scheduling, plant nutrition, greenhouse management, and pest management influence quality. Some vegetable producers choose to purchase transplants while others grow their own.
