Common questions

How much water does marigold need?

Marigold has middle-of-the-road water needs. Aim to keep soil moisture around 25–50%, letting the top inch dry slightly between waterings rather than staying soggy.

Can I grow marigold in a raised bed or container?

Yes — marigold does well in raised beds and is happy in a decent-sized container too, as long as drainage is good.

Does marigold come back every year?

No — marigold is an annual. It completes its life in one season, so you replant it each year.
