Tomatoes need six to eight hours of sunlight a day, so you should consider which spots in your yard have the most sun to avoid planting them in any shaded or windy areas.
If your plants are struggling to stay warm, grow them against a south- or west-facing wall, which will absorb the sun’s heat throughout the day and keep the tomatoes warm at night.
Tomatoes also need plenty of room to grow. Long-vined and indeterminate types need to be placed 3 feet apart, while determinate varieties need to be 2 feet apart.
Plant your tomatoes in well-draining, nutrient-dense soil with a pH level between 6.2 and 6.8 to aid their growth. Adding calcium fertilizer or compost also helps them thrive.
