A variety for mid to late summer harvest, performing best with a long day length that is accompanied with moderate heat. A dependable choice for growing in the northeastern summers. Domed heads are dark green with small beads and have a excellent post harvest shelf life.

30 seeds

PLANTING

Brassica oleracea

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 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.

    First time broccoli

    It was so easy to order and the seeds arrived in almost no time. Some of the broccoli seeds were started inside in March (March 6) due to our very short growing season. Some of the seeds were direct planted in the raised beds when the temps were appropriate (Mar 6th). The plants have reached the same height and maturity at this time. Small clusters of broccoli are almost ready for harvest. I grow these plants under very light covers to keep the cabbage moths and cabbage loopers off the plants and have had no problems. I removed the covers about two weeks ago and still have no damage to the plants. These are strong and healthy plants.
