Growing Broccoli Tips
Below you'll find simple tips on when to plant, how much space and water broccoli needs, and how to know when it’s ready to harvest—everything you need for a thriving crop:
When to plant broccoli?
- Plant broccoli in early spring or late summer for a fall crop—broccoli thrives in cooler weather.
- Start seeds indoors 6–8 weeks before your last expected spring frost.
- Transplant seedlings outdoors when they’re about 4–6 weeks old and daytime temps stay above 50°F.
- For fall harvest, sow seeds 10–12 weeks before the first expected fall frost.
How much space does broccoli need to grow?
- Space broccoli plants 18–24 inches apart in rows that are 24–36 inches apart.
- Give each plant enough room for the large leaves to spread and for good air circulation.
- Avoid overcrowding—tight spacing can lead to smaller heads and increase disease risk.
How much water does broccoli need?
- Broccoli needs 1 to 1.5 inches of water per week—more during hot or dry periods.
- Water at the base of the plant to keep the leaves dry and prevent rot.
- Use mulch around the base to retain moisture and regulate soil temperature.

When to harvest broccoli?
- Harvest when the central head is tight, firm, and deep green, about 4–7 inches wide.
- Cut the main head before the buds start to open or turn yellow—this signals flowering.
- Use a sharp knife to cut the stalk 5–6 inches below the head, leaving side shoots to grow for a second harvest.
