Harvest signs

Common questions
How much water does broccoli need?
Broccoli is water-sensitive — shallow roots and a steady thirst. Keep soil moisture in roughly the 40–60% range and don't let it dry out fully, or growth stalls and leafy crops turn bitter.
Can I grow broccoli in a raised bed or container?
Yes — broccoli does well in raised beds and is happy in a decent-sized container too, as long as drainage is good.
Does broccoli come back every year?
No — broccoli is an annual. It completes its life in one season, so you replant it each year.
