Kale can be planted at any time, from early spring to early summer. Be mindful, as hot weather makes kale bitter. If planted late in the summer, you can harvest it from fall until the ground freezes. Plant ¼ to ½ inch deep in an area with well-drained, loamy soil. If planting in cool season, select an area that will get full sun. Choose partial shade if growing in the warm season. Seeds will sprout best in soil around 70 degrees F. After 2 weeks, thin seedlings so they are spaced 8 to 12 inches apart. Water the plants regularly, but take care not to over water. Mulch the soil heavily after first freeze. The plants can sometimes produce leaves throughout the winter. Kale is ready to harvest when the leaves are about the size of your hands. Avoid picking the terminal bud at the top center of the plant, as this will keep the plant productive. Only pick about a fistful of leaves per harvest. Kale grows until it’s about 20 degrees F - a touch of frost actually sweetens the flavor.

Keep unused seeds dry and cool in a clearly labeled, closed container. Protect the packet from humidity and temperature swings, and retain the variety name and sowing notes for your next planting. Use the species-specific directions below when deciding whether to start indoors, sow directly, soak seeds, or provide a cold period. Germination and growth vary with seed handling and local growing conditions.
