How to grow marigolds
Determine what growing zone you live in.
The usda has defined 13 growing zones for the united states, ranging from the extremely cold zone 1 (in far-north alaska) to the extremely warm zone 13 (in parts of hawaii and puerto rico). Most of the country ranges from zone 3 to zone 10.
Marigolds are annual plants in most zones, meaning they will die in the winter and will not return the next growing season. Marigolds are hardy, self-seeding flowers.
