What are the horticulural aspects of Solanum lycopersicum?

Solanum lycopersicum grow best in temperatures between 65°F and 70°F (18°C and 21°C) with full sun and well-draining soil. Tomato plants require at least 6 hours of direct sunlight daily. Soil pH between 6.0 and 6.8 is optimal for growth.

To plant tomatoes, dig a hole 1-2 feet deep, depending on the variety. Add 1-2 cups of compost or well-rotted manure to improve soil fertility. Plant the seedling 1-2 inches deeper than the soil level, and water thoroughly. Space plants 18-36 inches apart, depending on the variety.

Tomatoes are typically ready to harvest 60-90 days after sowing. Check for ripeness by gently tugging on the fruit; ripe tomatoes will come off easily. Harvest regularly to encourage the plant to produce more fruit. Use scissors or a sharp knife to avoid damaging the fruit or stem.
