When to start seeds indoors

While growth dates may differ for each type of plant (and your plant's location, lighting, etc.), starting seeds indoors about six to eight weeks before the last frost date is generally recommended. You can look up your area's first and last frost date by typing in your zip code on websites like the Farmer's Almanac, which provides a comprehensive guide to planting and harvesting your crops based on your location.
