Gardeners in cool climates with short summers often start seeds inside in late winter or early spring to get a head start on the growing season. Transplanting seedlings to the garden after the danger of frost has passed in your area adds several weeks of growing time. Although most plants transplant well, some plants suffer when transplanted and require pots or flats that cause little or no disruption to the roots when transplanting. Jiffy peat pellets or pots provide the solution.
Till the soil in your planting site to a depth of 8 to10 inches. Amend with a 2- to 3-inch layer of compost or well-rotted manure and work it into the soil. Add the recommended fertilizer for the specific plants you are growing. 5-10-10 fertilizer is suitable for most garden vegetables.
Dig a hole large enough to set the entire jiffy peat pot into the hole, using a shovel. Cut individual cells apart, if seedlings are in trays with cells.
Place the peat pot into the soil so the plant rests at it original planting depth. Fill in around the pot with soil and firm down with your hands to secure in place. Roots grow through the sides and bottom of the pot into the surrounding soil.
Tear away the top of the jiffy peat pot, if it extends above the surface of the soil. Pots should not be visible. Firm the soil around the base of the plant.
Water thoroughly to moisten the soil to the root level. Keep moist until new growth appears. Reduce watering to once a week.
