Early Purple Sprouting Broccoli ( 120-200 Days )
The Early Purple Sprouting Broccoli is an old English type of broccoli that is planted out mid to late summer and requires overwintering to produce florets the following spring. Does best in mild climates and will need protection in ones that fall below 15 degrees during the winter.
Germination: 3-10 days
Germination Temperature: Optimum soil temperatures 65-85ºF.
Seed Sowing Depth: 1/4” deep
Starting Indoors: 4-6 weeks before 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 suggested measurement. Transplant a week or two before last frost. Space 12-18" apart. Sow in early to midsummer for fall crops.
Sowing Outdoors: Spring when soil temperature reaches at least 55ºF. Sow 2-3 seeds every 12-18” apart. Thin to the strongest seedling per space. Sow in midsummer for fall crops. Germination is slower at lower soil temperatures.
Harvest: Pick when heads are tight before flower buds starts to open. For varieties that produce side shoots keep picked for a longer production
Tips: Provide Early Purple Sprouting Broccoli with fertile soil, rich in organic matter from the very beginning of its growth in the garden. Give adequate, even moisture for the best growth. Mulching helps retain moisture.
