Starting seeds indoors

Quick facts

  • When selecting vegetable varieties, check packets for the number of days until harvest to be sure your choices will ripen before frost.
  • Many long-season vegetables must be started indoors in early spring.
  • Many annual flowers need an indoor start if they are to bloom during the summer.

Starting garden plants from seeds indoors can be an enjoyable project for any gardener. It's a relatively inexpensive way to grow a wide variety of plants. Many garden favorites are found in a greater variety of colors, sizes and growth habits as seeds, rather than as started plants.
