- Species and varieties: Large cherry tomatoes belong to the species Solanum lycopersicum. They are a type of cherry tomato known for their larger size compared to typical cherry tomatoes. Varieties include 'Black Cherry', 'Sun Gold', 'Sweet Million', and 'Super Sweet 100'.
- Hybrid or heirloom: Large cherry tomato seeds can be either hybrid or heirloom. Hybrid varieties, such as 'Sun Gold' and 'Sweet Million', are bred for specific traits like disease resistance and high yield. Heirloom varieties, like 'Black Cherry', are open-pollinated and have been passed down through generations, often prized for their unique flavors.
- Pruning and training: Pruning and training are essential for large cherry tomatoes to ensure healthy growth and high yields. Remove suckers (the shoots that grow between the main stem and branches) to promote better air circulation and prevent disease. Support the plants with stakes, cages, or trellises to keep the vines off the ground and make harvesting easier.
- Fertilization needs: Large cherry tomatoes benefit from regular fertilization. Use a balanced fertilizer (such as 10-10-10) at planting time and switch to a high-phosphorus fertilizer (such as 5-10-10) when the plants start to flower. Avoid excessive nitrogen, as it can lead to lush foliage but fewer fruits. Mulching around the plants can help retain moisture and suppress weeds.
- Hardiness zones: Large cherry tomatoes can be grown in USDA hardiness zones 3-11. They thrive in warm climates and are typically grown as annuals in most regions.
- Climate requirements: Large 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 prefer well-drained, fertile soil with a pH of 6.0-6.8.
