Red Russian Kale Seeds grow leaves that are flat, toothed, grey-green leaves with purple stems and veins really brighten after frosts. Tender for salads and good for bunching, the red and purple hues turn a rich, dark green colour when cooked. It may be richer in vitamins and minerals than other greens and is very disease resistant. This old time heirloom kale eventually goes to seed, producing tall towers of yellow flowers followed by edible seed pods. Seed saving is easy with kale, but don’t let the plant drop its seed in your garden, or there will be kale in your future for years to come.
Timing: Direct sow in early spring to mid-summer for summer to winter harvests. Or start indoors 4-6 weeks before the last frost, and transplant out as soon as the soil warms up. Optimal soil temperature: 10-30°C (50-85°F). Seeds should germinate in 7-10 days.
Starting: Sow 3-4 seeds 5mm (¼”) deep in each spot you where a plant is to grow. Thin to the strongest plant. Space 45-60cm (18-24″) apart in rows 75-90cm (30-36″) apart.
Growing: Ideal pH: 6.0-6.8. Add lime to the bed 3 weeks prior to sowing. Kale likes well-drained, fertile soil high in organic matter. This plant prefers plentiful, consistent moisture. Drought is tolerable, but quality and flavor of leaves can suffer. Mix ¼ cup of complete organic fertilizer into the soil beneath each transplant, or use 1 cup beneath every 3m (10′) of seed furrow.
Harvest: Kale and collards can both be grown as a cut and come again crop for salad mixes by direct-seeding and cutting baby leaves. They will re-grow if you pick leaves from the bottom up, as you need them. Continue harvesting lower leaves as they mature—plants will keep producing all season. Kale can overwinter in many areas. In fact, the leaves get sweeter after frost, though growth will slow. In spring, the surviving plants start to flower, so eat the delicious flowering steps and buds.
Diseases & Pests: Protect from cabbage moths and other insect pests with floating row cover. Prevent disease with a strict 4-year crop rotation, avoiding planting Brassicas in the same spot more than once every four years.
