Planting tomatoes
Start tomatoes indoors about 6 to 8 weeks before the expected last frost. Move them outside after frost risk has passed, nights are reliably mild, and the soil has begun to warm.
Planting details
- Start indoors: 6 to 8 weeks before the last frost
- Transplant: after frost risk has passed
- Spacing: 18 to 24 inches for many supported plants
- Seed depth: about 1/4 inch
Growing requirements
Choose the sunniest position available. Tomatoes grow best with consistent moisture and well-drained soil. Irregular watering can split fruit and can contribute to blossom-end rot when calcium uptake is disrupted.
Companion plants
Basil, carrots, onions, and parsley can share a garden area with tomatoes when each plant still receives enough light and root space. Spacing and airflow matter more than a simple companion list.
