When can I plant marigolds outdoors?


Two planting options are available when planting marigolds.  Most gardeners set out plants in spring.  However, gardeners can also sow marigold seeds directly outdoors. 

Plant marigold seedlings outdoors after the danger of frost is past.  It’s usually safe to begin planting marigolds in late April in southern Iowa and mid-May in northern portions of the state.  Plants purchased at greenhouses or started indoors should be hardened or acclimated to outdoor conditions  for several days prior to planting.  Initially place plants in a shady, protected location and then gradually expose them to longer periods of sunlight. 

Sow marigold seeds outdoors when the danger of frost is past.  Plant seeds one-quarter inch deep.
