I’ve never grown kale, but I want to try it in my kitchen garden this year. Is it better to start with seeds or transplants? When is the best time to plant it?
Kale has become a culinary star for its flavor and its reputation as a nutrient-dense superfood. Fortunately, it’s a vegetable that’s easy to grow. It’s also one of those early-season garden favorites that thrives in cooler weather, so you can plan to begin planting it in early spring, as soon as the soil can be worked (in Middle Tennessee — USDA Hardiness Zone 7a, where The Garden Bench calls home — that could be late February or early March). It’s even better as a fall crop. Plant it again in late summer to grow and harvest into winter.
You can plant transplants, but it’s just as easy to sow seed directly in the prepared garden bed. Like most vegetables, kale grows best in full sun. Plant it in loamy soil that you may amend with high-nitrogen fertilizer. Sow in rows, or broadcast the seed over the area, spacing the seeds an inch or two apart. Cover with about ¼ inch of soil and keep the soil moist as the seed germinates. The seed company Renee’s Garden provides a video about planting kale that you can watch here. You can also grow kale in containers.
Thin seedlings as they begin to sprout; you can use the small, tender leaves in salads. Harvest by cutting the outside leaves of a plant as they get large enough to use; the crown of the plant will continue to grow.
Kale is a member of the same family as cabbage, broccoli and other Brassicas, and as such may need protection from cabbage worms and cabbage loopers. Row covers can keep adult insects from laying eggs on the plants as they grow.
There are several varieties of kale – smooth and curly leaf types, large, sturdy leaves and smaller, tender leaves, dark green, light green and purple-green varieties. (Ornamental kale, usually sold in fall to enhance landscapes with its frilly, brightly colored leaves, is edible but not as tasty as the leaves grown for culinary use.) There are dwarf varieties suitable for small plots and containers.
