What's the Best Month to Start Tomato Seeds?

Timing is everything when it comes to growing tomatoes. For most areas, starting seeds indoors 6–8 weeks before the last frost date is ideal. This typically means late winter or early spring. If you’re in a warmer climate, you may be able to start earlier and transplant sooner.

How Long Does It Take to Grow Tomatoes From Seed?

Tomatoes vary in growth time depending on their type:

  • Determinate tomato seeds: Produce their crop all at once, usually in about 65–85 days.

  • Indeterminate tomato seeds: Keep growing and producing until frost, taking around 70–100 days.

The key is to start early, and you’ll enjoy fresh, homegrown tomatoes all season long.

Do You Need Organic or Heirloom Tomato Seed Varieties?

Choosing the right type of tomato seed depends on your gardening goals:

  • Organic tomato seeds are grown without synthetic chemicals, perfect for eco-conscious gardeners.

  • Heirloom tomato seeds offer rich flavors and unique shapes, passed down through generations.
