Starting Seeds Inside

Last week I started flower and herb seeds under grow lights. Some are already germinated and growing!  Growing your own transplants is a great way to add annuals, perennials and herbs to your landscape for pollinators. I started basil, borage, blue salvia and calendula.

Spindly growth is a common problem when growing transplants indoors. It is best to place the seedlings under artificial light.  It is not necessary to have a grow light plant stand. A standard shop light fixture with one cool and one warm fluorescent tube light works fine. For best results, the lights should be approximately 1 inch above the seedlings. Raise the light as the seedlings grow.  Leave the lights on 12 to 16 hours a day.

Many flowers do well or better as direct planting outside. Plant zinnia and sunflower seeds after the chance for frost has past and the ground temperature is consistently warm, over 55 degrees F. This usually occurs in mid to late May.
