What Are the Tips for Growing Greenhouse Tomatoes in the Heat?
To prevent heat stress and flower drop in greenhouse tomatoes, use 40-70% shade cloth to reduce temperature and light intensity, maintain good air circulation with fans and open screen doors, and regularly water soil and paths to cool the environment and increase humidity. Selecting heat-tolerant tomato varieties, like smaller-fruited types or proven heirlooms such as Juliet and Cherokee Purple, helps ensure fruit set during hot spells.
