Before putting them in the garden, all plants should go through a hardening-off period. For proper timing, check ISU Extension publication Planting and Harvesting Times for Garden Vegetables, PM-534. Seeds that have been sown in rows will need thin-ning out when they reach 2 to 4 inches or when they have their first true leaves. Some vegetables such as radish and lettuce can be used as they are pulled up when thinning. Thinning improves the quali-ty while avoiding stunting and distorting of the plants.
Transplants can be start-ed at home or purchased.
Often it is more economical to purchase at the garden store than try to raise plants at home, especially if only a few plants are needed. Before transplanting in the garden have the plants acclimatized by leaving them in a shady location for a few days. Transplant the seedings in the late evening or on a cloudy day and let the dis-tance of the roots be minimal. Feed each plant with 1-2 cups of liquid garden fertilizer. Fill peat pots with good potting soil and plant about three seeds in each pot.
