Kale Care
Kale grows best in full sun and moist, well-drained soil. Although kale leaves acquire their best flavor after autumn’s first frost, this plant can also be grown in early spring. Start it from seed indoors about eight weeks before the last average frost date. Those seedlings—or transplants from the garden center—can be planted in the garden a couple of weeks after all danger of frost is past. In cold climates, sow seeds outside as soon as the soil reaches 45 degrees F and the ground can be worked. Sow seeds 2 inches apart in rows 2 to 18 inches apart. Plant seeds ½ inch deep and keep soil evenly moist to ensure good germination. In warm climates, harvest a fall drop by planting seeds inside by early July, then transplanting the seedlings outside in the garden by mid-August. Water the plants well, as moist soil helps keep the leaves sweet and crisp instead of bitter. Care for crops planted in late summer by mulching around plants to delay the ground from freezing around roots. Pull and discard plants as soon as they begin to flower; those leaves are tough and bitter.
