Broccoli Planting Guidelines
Choose the right broccoli variety: There are several types of broccoli to choose from, including standard green broccoli, purple broccoli, and broccolini. Choose a variety that is suited to your climate and growing conditions.
Prepare the soil: Broccoli prefers a well-draining, nutrient-rich soil with a pH between 6.0 and 7.0. Work in compost or aged manure to improve the soil’s fertility, and loosen the soil to a depth of at least 12 inches.
Start Broccoli seeds indoors: Broccoli can be started from seed indoors 6-8 weeks before the last expected frost date. Sow seeds 1⁄4 inch deep in small pots, and keep them in a warm, sunny location until they germinate.
Transplant seedlings: Once the seedlings have grown to about 4-6 inches tall, transplant them outdoors to a prepared garden bed. Space them 18-24 inches apart in rows that are 24- 36 inches apart.
Water and fertilize: Water your broccoli plants regularly to keep the soil evenly moist. Fertilize with a balanced fertilizer every 3-4 weeks.
Protect from pests and diseases: Cover your broccoli plants with row covers to protect them from pests such as aphids, cabbage worms, and flea beetles. Remove the covers once the plants begin to flower to allow for pollination.
Common Problems When Growing Broccoli
Pests: Broccoli is vulnerable to several pests, including aphids, cabbage worms, and flea beetles. To prevent these pests, cover your plants with row covers and remove them once the plants begin to flower. You can also use natural pest control methods such as neem oil, insecticidal soap, or introducing beneficial insects such as ladybugs and lacewings.
Disease: Broccoli can be susceptible to several diseases, including clubroot and blackleg. To prevent these diseases, rotate your crops to a new area each year and avoid planting in soil where other brassica crops have grown. You can also use disease-resistant varieties and keep your plants well-watered to prevent stress.
Bolting: Broccoli can bolt or go to seed if it is exposed to high temperatures for too long. To prevent this, plant broccoli in a location that gets some shade during the hottest part of the day and keep the soil evenly moist.
Nutrient deficiencies: Broccoli can be susceptible to nutrient deficiencies, particularly if the soil is not well-draining or if there is not enough nitrogen in the soil. To prevent this, add compost or aged manure to the soil before planting and fertilize regularly with a balanced fertilizer.
Companion Planting with Broccoli
Beets: Beets are a great companion for broccoli because they help repel pests such as aphids and leaf miners.
Chamomile: Chamomile is a natural insect repellent and can help deter pests from your broccoli plants. It also improves soil fertility and can be used as a natural mulch.
Dill: Dill attracts beneficial insects such as ladybugs, which can help control pests that might attack your broccoli plants.
Spinach: Spinach is a good companion for broccoli because it provides shade to the soil, which helps keep it cool and moist.
Nasturtium: Nasturtiums are a great companion for broccoli because they repel pests such as aphids and cabbage worms. They also attract beneficial insects and add color to your garden.
Marigolds: Marigolds are a natural pest repellent and can help protect your broccoli plants from pests such as nematodes.
