Growing notes
Chard is a biennial that will not flower until it has lived through a winter, so there is no danger of bolting in summer heat. It does best in cooler weather and can withstand drought-like conditions but will not produce new leaves during dry spells.
Harvest signs

Common questions
How much water does swiss chard need?
Swiss Chard 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 swiss chard in a raised bed or container?
Yes — swiss chard does well in raised beds and is happy in a decent-sized container too, as long as drainage is good.
Does swiss chard come back every year?
No — swiss chard is an annual. It completes its life in one season, so you replant it each year.
