- Species and varieties: Red cherry tomatoes belong to the species Solanum lycopersicum. They are a popular variety of cherry tomatoes known for their small, round, and sweet fruits. Varieties include 'Sweet 100', 'Super Sweet 100', 'Cherry Belle', and 'Tiny Tim'.
- Hybrid or heirloom: Red cherry tomato seeds can be either hybrid or heirloom. Hybrid varieties like 'Super Sweet 100' are bred for disease resistance and high yield, while heirloom varieties like 'Cherry Belle' are valued for their rich flavor and historical significance.
- Pruning and training: Pruning and training are essential for red cherry tomatoes to promote healthy growth and increase yield. Remove suckers (side shoots) that develop in the leaf axils to focus the plant's energy on fruit production. Support the plants with stakes, cages, or trellises to keep them upright and prevent sprawling.
- Fertilization needs: Red cherry tomatoes benefit from regular fertilization. Use a balanced fertilizer (e.g., 10-10-10) at planting time and switch to a high-phosphorus fertilizer (e.g., 5-10-10) once the plants start flowering. Avoid excessive nitrogen, as it can lead to lush foliage but poor fruit production. Mulching and consistent watering are also important to maintain soil moisture and prevent blossom end rot.
- Hardiness zones: Red cherry tomatoes are typically grown as annuals in USDA hardiness zones 3-11. They thrive in warm climates and are not frost-tolerant.
- Climate requirements: Red cherry tomatoes require a warm, sunny climate with temperatures between 70-85°F (21-29°C) for optimal growth. They need at least 6-8 hours of direct sunlight daily and well-drained soil with a pH between 6.0 and 6.8.
