We suggest Eastern Magic or Green Magic Broccoli as replacements
The Arcadia Broccoli is great to grow in a compact space. Tightly domed 6-8” heads have small to medium-sized beads then continues on with a bumper crop of side shoots. Good freezing variety and wide seasonal adaptability. Disease Resistance- black rot, downy mildew, head rot, and heat stress.
Germination: 3-10 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 early to midsummer for fall crops.
Sowing Outdoors: Spring when the 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 start to open. For varieties that produce side shoots keep picked for a longer production
Tips: Provide Arcadia 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.
