CULTURE: Collard greens need cool weather, loose, well drained, healthy soil. Normal water and fertility requirements. Collard greens that mature in cool weather will have the best flavor. If color is desired from the kale, don't over fertilize.
PROBLEMS: Cutworms, aphids, harlequin bugs, downy mildew, flea hoppers, loopers, and boron deficiency.
HARVEST: Harvest young leaves as needed for cooking. Flavor is better after a frost. Can be stored up to 3 weeks at 32-40°.
NOTES: Kale is one of the best winter color plants. Both, especially the collards, do well from seed because they develop a deeper root system.
