Harden the seedlings by slightly reducing water and exposing them directly to sunlight 6-9 days before transplanting. Thoroughly water the seedlings about 12 hours before transplanting to the field. A good seedling is in the 4- or 5-leaf stage (about 4 weeks old), vigorous and stocky.

Transplant in the late afternoon or on a cloudy day to minimize transplant shock. Insert the seedling in a hole so the cotyledons appear above the surface. Tall, spindly seedlings should be buried deeper. Press soil firmly around the root, and water around the base of the plant to settle the soil. Irrigate the field as soon as possible after transplanting.
