In agriculture and gardening, transplanting is the technique of starting a plant from seed in optimal conditions, such as in a greenhouse or protected nursery bed, then replanting it in another, usually outdoor, growing location.

Transplanting has a variety of applications, including:

• extending the growing season by starting plants indoors, before outdoor conditions are favorable;
• protecting young plants from diseases and pests until they are sufficiently established;
• avoiding germination problems by setting out seedlings instead of direct seeding.

Different species and varieties react differently to transplanting; for some, it is not recommended. In all cases, avoiding transplant shock is the principal concern. Plants raised in protected conditions usually need a period of acclimatization, known as hardening off. Also, root disturbance should be minimized. The stage of growth at which transplanting takes place, the weather conditions during transplanting, and treatment immediately after transplanting are other important factors.
