11 Vegetable Plants to Start Indoors Before Spring
Start planting nutritious vegetables before the ground thaws with these indoor gardening tips.
Plantings must be timed so that the clusters of small flower buds the plant produces can be harvested while the days remain cool. For best results, start the seeds indoors four to six weeks before the time to set out the seedlings, which you should calculate as two weeks before the date of the last expected frost.
Early cabbage should be sown indoors five to eight weeks before the last expected frost. You can also grow early cabbage from seedlings bought in a nursery.
For spring plantings in most areas, start cauliflower seeds indoors six to eight weeks before the last expected frost. Sow the seeds in individual pots, three or four seeds to a pot. Keep the seedlings in sunny, cool spot.
Eggplant is particularly difficult to grow. The seeds must be sown indoors at least eight weeks before the plants are set out, and the seedlings require sunshine and warm moist soil. To encourage germination, soak the seeds in warm water for 24 hours before sowing.
Leeks take 130 days to mature, so the seeds should be sown indoors in most areas. Start them 10 to 12 weeks before the date of the last expected frost.
Time to maturity for onions is considerable: three to five months from seed, although scallions can be harvested as early as two months after sowing.
