When to Sow Based on Hardiness Zone

Your USDA Plant Hardiness Zone plays a crucial role in determining when to sow kale seeds. The higher your hardiness zone number, the earlier you can start growing kale in the spring and later in the fall. Additionally, knowing your predicted last frost date in the spring and first frost date in the fall will help you plan your planting schedule effectively.

When to Sow in the Spring and Fall

Kale is a cool-weather crop that thrives in the spring and fall when temperatures are mild. In the spring, you can plant kale seeds directly in the garden after the last frost date. Alternatively, you can start seedlings indoors four to six weeks before the last frost date for earlier harvests.

For fall planting, ensure that your kale plants have enough time to mature before the days become shorter. The Persephone Period, as described by Eliot Coleman, marks the time when days are less than ten hours long. To ensure a successful fall harvest, sow seeds directly in the garden from mid-July to mid-September.

How to Time Succession Plantings

Succession planting is a great technique for ensuring a continuous supply of baby kale throughout the growing season. By planting seeds every two to three weeks, you can enjoy a steady harvest of fresh greens. Consider spacing out your successive plantings based on the available daylight. Closer plantings may be required in months with less sunlight to accommodate slower growth.

Tips for Planting Kale Seeds

Now that you have a better understanding of when to plant kale seeds, it’s time to put your knowledge into action. Here are some tips to help you get started:

Choose a sunny location for your kale plants to thrive.
Ensure that the soil is well-drained and rich in organic matter.
Water your kale plants regularly, especially during hot weather.
Mulch around the base of the plants to retain soil moisture and suppress weeds.
Monitor for pests and diseases and take appropriate action if needed.
