When Should Kale Be Planted

Soil, Planting, and Care. Set out plants in spring 3 to 5 weeks before the last frost; in late summer, you can begin planting kale 6 to 8 weeks before the first frost for fall and winter harvests, and continue planting throughout the fall in zones 8, 9, and 10.

When can I plant my kale outside?

As a general rule of thumb, plant kale seedlings outside in late winter to early spring, as early as 3 or 4 weeks before your last average frost date. Seeds can be started indoors even a few weeks earlier. Protect tender young seedlings from hard frost after planting with frost cover or cloches.

What should not be planted next to kale?

Avoid planting kale with other brassicas (like broccoli, kohlrabi, cauliflower, brussels sprouts, and Swiss chard), as they can fall prey to the same pests and diseases.
