Quick Answer:

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. Combining these strategies allows growers to maximize tomato yields and extend the harvest season even in extreme summer heat.

The Trouble with Greenhouse Tomatoes

Do your greenhouse tomatoes have heat stroke?

If your tomato blooms are bending and falling off, flower and all, they are having a heatstroke. When extreme heat hits, greenhouse tomatoes fail to set fruit even as the leaves keep growing and new blooms appear.

 

My crazy dogs

Corle ran ahead of me on the beach and stuck her head right into a dead seal. And then she took a big bite. 

Arnold is always hungry. And some of his favorite foods are the fruits and vegetables I grow in my greenhouse.  He also eats the plants of the tomatoes and squash I grow. He gently pokes around, licking up the small green fruits first and then chomps down on the whole tangled twisted plant.

My tomatoes are sitting beside me in the front seat of my shiny black station wagon. We are on our way to the fair!
