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.

When can I move my amaryllis outdoors?

Answer: 

The amaryllis can be moved outdoors in late May.  When the amaryllis is moved outdoors, harden or acclimate the plant to the outdoor environment by initially placing it in a shady, protected area for 2 or 3 days and then gradually expose it to longer periods of direct sun.  Once hardened, select a site in partial to full sun.  Dig a hole and set the pot into the ground.  Outdoors, water the plant during dry weather.  Also, fertilize the amaryllis once or twice a month through July with a soluble houseplant fertilizer.  Bring the plant indoors in mid-September.
