Growing Tips, Tricks and FAQs
Growing Tips
Calabrese Green Sprouting broccoli prefers full sun and rich, well-drained soil. It's important to maintain consistent moisture and use mulch to conserve water and control weeds. Adding organic matter can enhance soil fertility. Regular feeding with a balanced fertilizer will encourage healthy growth.
When to Grow
This broccoli variety prefers 60-80 F, making it ideal for planting in early spring or late summer. It can tolerate light frost, which can even enhance its sweetness. For specific freeze/frost dates, consider looking up the average last and first frost dates for your area or your USDA hardiness zone.
How to Sow and Plant
Sow very early indoors, or direct seed outdoors 2-4 weeks ahead of last frost date and again in midsummer for fall harvest. Sow seeds 1/4 to 1/2 inch deep in trays filled with good-quality potting mix. Keep the soil moist and provide plenty of light. Space plants 12 inches apart when transplanting.
How to Grow
Ensure plants receive at least 1-1.5 inches of water per week. Use a balanced fertilizer every 3-4 weeks. Keep the soil evenly moist to avoid bolting. Harvest the central head first to encourage side shoot production, providing a longer harvest period.
How to Save
Broccoli is considered to be a more challenging crop for seed saving. It is a biennial and will not flower until its second year of growth.
It is easy to keep broccoli alive over winter in climates where the winter is mild. Northerners will need to get creative; established broccoli is not tolerant of temperatures below 20 F.
FAQ

Can Calabrese Green Sprouting broccoli be grown in containers?
Yes, but ensure the container is deep and wide enough to accommodate root growth, and receives plenty of sun and water.
What pests can affect Calabrese Green Sprouting broccoli?
