Month 1: Starting Seeds Indoors (February – March)

To get an early start, begin sowing tomato seeds indoors about 6–8 weeks before the last expected frost in your area.
- Use a high-quality seed-starting mix.
- Keep the soil moist but not soggy.
- Place seedlings under grow lights or near a sunny window to prevent legginess.

Month 2: Transplanting Seedlings (March – April)
Key Tasks: Hardening off, transplanting into pots, pruning
Once your seedlings have grown two sets of true leaves, it’s time to move them into larger containers.
- Gradually expose them to outdoor conditions — a process known as hardening off .
- Use nutrient-rich potting soil and consider adding compost for extra nourishment.
- Prune lower leaves if they touch the soil to avoid disease.

Month 4: Planting Outdoors (May – June)
Key Tasks: Planting depth, spacing, staking
Now that all danger of frost has passed, it’s time to plant your tomatoes outside.
- Bury two-thirds of the stem — tomatoes develop roots along the buried portion.
- Space plants 2–3 feet apart for good air circulation.
- Install stakes or cages immediately to support future growth.
