Tomatoes are very sensitive to cold, so it's crucial to plant them after the last expected frost date in your region.
Experts recommend that the soil temperature should be at least 60°F (15°C) for optimal growth. Too cold of soil can stunt tomato growth and hinder root development.
Different tomato varieties thrive in different climate zones. Be sure to select a variety that suits your local climate, and plant it at the right time according to your USDA hardiness zone.
For cooler climates, starting tomato seeds indoors 6-8 weeks before your average last frost date can give your plants a head start, allowing them to grow stronger before being transferred outside.
If you're transplanting seedlings from indoors, ensure they have developed a strong root system and are hardened off (gradually acclimated to outdoor conditions) before planting outdoors.
Even though daytime temperatures may be warm enough, night temperatures can dip and damage young tomato plants.
To thrive, tomatoes need warm, bright days. For optimal growth and fruit output, plant them in constant warm weather between 70°F to 85°F (21°C to 29°C).
