Disease and somewhat cabbage moth resistant. High in potassium and vitamin C. Limit one packet per customer. Tags: Blue Green, Spring Fall.

How to grow sea kale from seed, division

Start indoors 4-6 weeks before last frost or direct sow in March or April in seed bed outdoors. Germination is variable even with fresh seed, typically 1–3 plants out of ten sown. We pot up the first year and raise in a partial shade nursery, then transplant after last frost the second year. Prefers rich deep sandy loam soil, loosen soil to 1’. May be divided by root cuttings after third or fourth year. Scarify, remove the round husk that holds the seed for better germination by rolling seeds between two cutting boards, a great kids activity. Needs winter protection in Zone 6 or cooler to prevent ground from freezing. Enjoy, a farm favorite. Soil pH 6.6-7.8. Hardiness zones 5–9.

Days from maturity calculated from the date of seeding. Average 3,015 seeds per ounce. Germination in optimal conditions: 50-65%. Usual seed life 3-4 years. Isolation distance for seed saving: 1/2 mile.
