Broccoli Seed Planting Information:

Broccoli does best when temperatures remain between 40 F and 70 F during the growing period. Temperatures below 25 F can damage or kill broccoli. Spring planting should occur as soon as soil can be worked and after last frost, and fall planting done 10 to 12 weeks before first frost. In most areas broccoli grows best if planted in late summer so it can mature during cool periods. Plants can grow 2 ft tall.

Soil Requirements:

Requires fertile soil with plenty of nitrogen and calcium with some lime. Apply much and grass clippings, or straw around base of plant.

Water Requirements:

Keep well watered or plant will have premature heading and flowering.

Fertilizer Requirements:

Use RootBlast, Vegetable Alive, and Slow Release Fertilizer when transplanting outdoors. Periodically apply Miracle Gro.

When you begin to see the buds spread out, it is time to harvest. Cut heads with sharp knife.

CR – Clubroot

Scientific Name: Plasmodiophora brassicae

Type: Fungus


Clubroot is a world-wide fungal soil-borne disease that affects the growth of cabbage, cauliflower, broccoli, Brussels sprouts, kohlrabi, radishes, rutabaga, tomatoes, and turnips. This disease can cause severe crop yields and total crop loss. The fungus infects the plant through root hairs or wounds. Symptoms include wilting and yellowing of leaves. Young plants are stunted and may die. The roots are usually swollen and distorted (clubbed). The disease is spread by farm equipment, wind, and water. The infected plants should be removed and burned to avoid further infestation. The disease is favorable when temperatures are 54-81 F and usually occur when soil is moist. The disease is primarily associated with acid soils. Plan on using a 7 year crop rotation and avoid planting in the same location, year after year, as the disease can survive in the soil up to 20 years. Use proper weed control techniques. Proper tillage practices may be helpful in managing the disease. It is essential that hydrated lime be added each year to the soil unless the soil pH exceeds 7.5. Thoroughly clean equipment after working in a field. Plant crops in well drained soil. The best option is to use disease resistant varieties.
