Late Flat Dutch is mentioned in Wickson’s 1913 bookCalifornia Vegetables as a great variety for the state. This what he says in general about cabbage growing in California “The cabbage can be grown everywhere in California by selecting that season of the year which furnishes the adequate moisture and moderate temperature which best suits its nature. These requirements adapt it well to winter growth generally in California except in the frostiest places, and give the plant a longer season and a greater attainment in weight in regions of rich soils open to coast influences. It does not resent fogs and cold winds, and thrives directly upon the coast as well as in coast valleys”.
Cabbage is rich in vitamin C and several cancer preventing phytochemicals (anthocyanins, sulforaphane, isothiocyanates, dithiolethiones). It has been found that people who eat lots of Brassicas, have lower cancer rates than those who don’t.
Sun: Full Sun
Optimum Soil Ph: 6.0 – 7.50
Days To Maturity: 60-100
Sowing Method: Outdoor
Start spring seedlings 4-5 weeks before transplanting. Start fall transplants 2-3 months before first frost. Transplant out to the garden when 3” tall at least 90 days before your first frost in midsummer. When transplanting, enrich soil with a little blood and bone meal. Needs cool temperatures to head properly – will bolt in heat. Keeping soil evenly moist is a must for a healthy crop.
Set out your spring cabbage transplants early enough so that they can mature before the heat of summer, about 5 weeks before the last frost. For a longer cabbage harvest plant 2 or 3 varieties with different maturities.
Soil: Surprisingly heirloom organic cabbage will do well on heavy clay soil, although it prefers a rich heavy loam. It delights in copious amounts of composted manure mixed into the soil bed. Remember not to plant cabbage seed in the same place year to year. The soil pH should be between 6.0 and 7.5 for optimum growth and to discourage clubroot disease.
