Kale Seeds

When to Plant Kale Seeds

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.

Where to Plant Kale Seeds

For best results, choose 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.

How to Plant Kale Seeds

Plant ¼ to ½ inch deep in your garden. 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.

How to Harvest Kale

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.
