Product Details

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. Winner of the RHS Award of Garden Merit.

These seeds may be coated with an inert, organically certified layer which helps to minimize clumping in storage and seed sowing machines. The coating is approved by organic certifiers in Canada, the US, EU, and Japan.

Matures in 50 days. (Hybrid seeds)

All About Redbor F1

Latin

Latin
Brassica oleracea var. acephala
Family: Brassicaceae

Difficulty

Difficulty
Easy

Season & Zone

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

Timing

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

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

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

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

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

Companion Planting
All Brassicas benefit from chamomile, dill, mint, rosemary, and sage. Avoid planting near eggplants, peppers, potatoes, or tomatoes, as the acidic soil these plants thrive in can cause problems for Brassicas.

How to Grow Kale

Step 1

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.

Step 2

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.

Step 3

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.

Step 4

Germination

Days to maturity: From transplant date.

In optimum conditions, at least 80% of seeds will germinate.

Step 5

Harvest

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.
