amount of sunlight to grow tomato
Tomato plants that receive less than 8 hours of sunlight a day produce fewer and smaller fruits. Tomatoes thrive in full sun and fertile, well-drained, slightly acidic soil with a pH between 6.0 and 6.8. For healthy growth, tomato plants require at least 8 hours of direct sunlight a day. However, the hours of sunlight do not need to be consecutive. This means that tomatoes can be grown successfully in both morning and afternoon sun as long as the number of hours adds up to 8 or more.
