Redbor kale seeds produce tall plants with the darkest red colour of all kales. After frost the leaves turn even darker and sweeter at the same time. Hybrid vigour means fast, uniform growth and consistent results every time. The splendid red leaves make excellent garnishes – they even look good in flower arrangements. Add finely chopped kale leaves to salads, or use the whole leaves cooked or in smoothies for a delicious blast of nutrients. A single serving of red kale contains 150mg of calcium, and that’s 15% of the recommended daily dosage.

Matures in 50 days. (Hybrid seeds)

Kale contains higher levels of beta-carotene than any other green vegetable, and is also high in vitamin C and calcium. Collards are not far behind. All are easy to grow, vigorous, nutritious, resistant to cold, and easy to harvest and prepare. And the greens even get sweeter after frost.  Follow along with this handy How to Grow Kale and Collards from Seeds Guide and grow healthy food! Perfect for juicing and long lasting green that stores well, delicious in crunchy salads.

Brassica oleracea var. acephala
Family: Brassicaceae


We Recommend: Lacinato (KL425). This is a summertime favourite. While Lacinato is less cold hardy than many of its cousins, it forms tall, almost architectural rosettes of substantial leaves. Packed with flavour and nutrients, it’s a great variety for the beginner kale farmer.
For Urban Gardeners: Dwarf Green Curled (KL423) stays smaller and more compact, and grows perfectly well in containers or raised beds. It’s also cold hardy, so well suited to winter harvesting.

Season & Zone
Season: Cool season
Exposure: Full sun
Zone: Winter hardy to Zone 6.

Direct sow March to mid-July for summer to winter harvests. Optimal soil temperature: 10-30°C (50-85°F). Seeds should germinate in 7-10 days.

Sow 3-4 seeds 5mm (¼”) deep in each spot you want a plant to grow.. Thin to the strongest plant. Space 45-60cm (18-24″) apart in rows 75-90cm (30-36″) apart.

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.

Kale and collards can both be grown as a cut and come again crop for salad mixes by direct-seeding and cutting when plants are 5-8cm (2-3″) tall. They will re-grow. Or pick leaves from the bottom up on mature plants as you need them. 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.

Companion Planting
All Brassicas benefit from chamomile, dill, mint, rosemary, and sage. Avoid planting near eggplants, peppers, potatoes, or tomatoes. Plant collards near tomatoes, which repel the flea beetles that so often look for collard leaves to eat.

    (verified owner):

    I purchased a 0.25g (approx 45 seeds) package in March 2015, back-ordered, and received a few months later (can’t remember when) but I was happy to receive them!
    The plants were, and still are beautiful, having survived over winter.

    One concern: the package front says Germ 83%, package back says “germination rate 60%”. During 2015 I planting 24 seeds in my garden individually, and only 7 plants grew. Now March 2016, I have planted the remaining seeds (20) in soil-less seed starting mixture and applying heat, and only 4 sprouted. So only about 25% germination rate.
    The package I received may have just been poorly fertilized/non-viable seeds from the harvesting seed farm.
    It has made me consider, but also be concerned about buying a larger bulk package this year, but having said that, I wonder if the germination is simply a Redbor variety thing, so I’m trying to find out myself in general, by saving seeds this year from the overwintered plants. Later in 2016 I will update this review based on my own seeds fertility, assuming I get hundreds of seeds.
