1. Temperature Issues
Tomatoes need the right temperatures to ripen properly. They thrive best at daytime temperatures between 70 and 85 degrees Fahrenheit. If it’s too hot or too cold, the ripening process can stall. To fix this, consider planting tomatoes in areas where they can get some afternoon shade if you live in a hot climate. During unexpected cold snaps, using row covers can help maintain warmth.
2. Lack of Sunlight
Tomatoes require plenty of direct sunlight—at least six to eight hours a day. If your plants are in a shaded area, they won’t receive the energy needed to ripen. Moving your plants to a sunnier location or trimming nearby foliage that casts too much shade can lead to better ripening.
3. Nutrient Imbalance
Excessive nitrogen can result in lush, green plants with minimal fruit ripening. Ensure you use a balanced fertilizer that provides adequate phosphorus and potassium. Avoid high-nitrogen fertilizers or too much compost rich in nitrogen. Instead, focus on formulations that promote fruit development.
