Incorporate 2 inches of compost and a dusting of kelp meal into the bed. Kale thrives in rich soil with good drainage, so raise beds slightly if rainfall is heavy.
Provide 1 inch of water weekly in spring and increase to 1.5 inches during hot spells. Apply moisture at the soil line to keep leaves as dry as possible.
Side-dress with compost monthly and apply a foliar spray of fish and seaweed after each major harvest to encourage fresh growth.
Harvest lower leaves as they reach 8 inches long, leaving the top crown intact. Remove yellowing leaves promptly to deter pests.
Pick after a light frost for sweeter flavor. Rinse leaves, spin dry, and store in a sealed container with a paper towel for up to a week, or blanch and freeze for soups.

| Issue | How to fix it |
|---|---|
| Cabbage worm damage | Use floating row cover, hand pick caterpillars, and apply Bt on overcast evenings. |
