Broccoli, a nutritious and versatile vegetable, is a beloved crop among Ontario gardeners. Its adaptability to our climate and ease of cultivation make it an ideal choice for both novice and experienced growers. In this comprehensive guide, we will delve into the intricacies of how to grow broccoli in Ontario, ensuring a bountiful harvest season after season.
Site Selection and Soil Preparation
- Sunlight: Broccoli requires ample sunlight, at least 6 hours per day.
- Soil: Well-drained, fertile loam with a pH between 6.0 and 6.8 is optimal. Amend the soil with compost or manure to improve fertility and drainage.
Planting Broccoli
- Transplanting: Start seeds indoors 6-8 weeks before the last frost date. Transplant seedlings into the garden when they have developed their first set of true leaves.
- Spacing: Space plants 18-24 inches apart in rows that are 30-36 inches apart.
- Depth: Plant seedlings at the same depth they were in the seed tray.
Watering and Fertilizing
- Watering: Water broccoli regularly, especially during hot, dry weather. Aim for 1-2 inches of water per week.
- Fertilizing: Fertilize broccoli every 3-4 weeks with a balanced fertilizer or manure tea.
Pest and Disease Management
- Aphids: Control aphids with insecticidal soap or neem oil.
- Cabbage loopers: Handpick or use Bacillus thuringiensis (Bt) to control cabbage loopers.
- Clubroot: Prevent clubroot by planting in well-drained soil and avoiding areas where it has been present in the past.
Harvesting Broccoli
- Cut heads: Harvest broccoli heads when they are 6-8 inches in diameter. Use a sharp knife to cut the head off the main stem.
- Storage: Store broccoli in the refrigerator for up to 10 days.
Troubleshooting
- Yellowing leaves: Yellowing leaves can indicate nitrogen deficiency. Fertilize with a nitrogen-rich fertilizer.
- Stunted growth: Stunted growth may be caused by poor soil drainage. Amend the soil with compost or raised beds to improve drainage.
- Bitter taste: Bitter broccoli can be caused by heat stress. Provide adequate shade and water during hot weather.
Tips for Success
- Rotate crops: Rotate broccoli with other vegetables to prevent soil-borne diseases.
- Companion planting: Plant broccoli with carrots, celery, or onions to improve growth and pest resistance.
- Overwintering: In mild climates, broccoli can be overwintered for a spring harvest. Protect plants with a thick layer of mulch.
