Opitko Chinese Cabbage is no longer available, we suggest Minuet Chinese Cabbage as a replacement
This compact, barrel-shaped Chinese Cabbage held the longest in the field and retained its flavor better than others we trialed. The Optiko CHinese Cabbage was the first to begin heading, though its zesty, mustardy flavor didn’t develop until the heads were large and firm. Uniformity in size and growth was remarkable as was its ability to stand in the heat of summer. The Optiko Chinese Cabbage is well suited for succession planting. Disease Resistance-fusarium yellow and tip burn.
Brassica rapa var. pekinensis
Germination: 7-12 days
Germination Temperature: Optimum soil temperatures 65-85ºF.
Seed Sowing Depth: 1/4” deep
Starting Indoors: 4-6 weeks before the last frost. Sow 2-3 seeds per cell/pot. Thin to the strongest seedling. Fertilize the seedlings every 7-10 days with a liquid or water-soluble fertilizer, diluted to ¼ of the suggested measurement. Transplant a week or two before the last frost. Space 12-18" apart. Sow in midsummer for fall crops.
Sowing Outdoors: Spring when the soil temperature reaches at least 55ºF. Sow 2-3 seeds every 12-15” apart for small headed varieties, 20-30” for large headed varieties. Thin to the strongest seedling per space. Sow in midsummer for fall crops. Germination is slower at lower soil temperatures.
How much does a packet plant: 15-20 foot single row
Harvest: If the heads feel solid by pushing on them lightly they are ready to harvest. Harvest as soon as possible for early varieties to prevent splitting. Later maturing varieties will hold longer.
Tips: The Optiko Chinese Cabbage needs to be provided with fertile soil, rich in organic matter from the very beginning of its growth in the garden. Provide adequate, even moisture for the best growth. Mulching helps retain moisture.
