Planting & Care

Sow Dwarf Siberian Improved Kale seeds directly in the garden or start indoors 4–6 weeks before the last frost. Plant seeds about 1/4 inch deep, keeping the soil evenly moist until germination. For a fall crop, sow seeds in mid to late summer. Thin seedlings to the recommended spacing to allow good air circulation. Kale performs best in fertile, well-drained soil and benefits from regular watering, especially during dry spells. Mulching helps retain moisture and suppress weeds.

Harvest outer leaves when they reach usable size, leaving the central growing point intact for continued production. Frost improves the flavor, so plants can be harvested well into cold weather. Watch for common pests such as aphids and cabbage worms, and protect plants with row covers if needed. With minimal care, this heirloom kale can provide a long season of fresh, nutritious greens.
