When the air temperature reaches 30 degrees Celsius or higher, tomato pollen becomes sterile, preventing the formation of ovaries and fruit. To avoid a reduced harvest, it’s crucial to take steps to protect your tomatoes during extreme heat.
Key Actions to Protect Your Tomatoes
- Timely Moistening of the Beds
If the soil has dried to a depth of 2.5 cm, it’s essential to thoroughly moisten the ground to keep the plants hydrated. - Manual Pollination of Flowers
During intense heat, natural pollination may not be effective. Pollinate the flowers manually by gently shaking the stem to disperse the pollen to nearby flowers. - Create Shade for the Bushes
To shield the tomato bushes from the harsh sun, you can:- Cover the bushes with thin fabrics or drape nets over them.
- Plant corn around the tomatoes to provide natural shade.
- Install a special turntable at a height of 2 meters to spray water and provide cooling mist over the beds.
- Ensure Good Air Circulation
Proper air circulation helps preserve the crop. Remove lower leaves on the shoots to improve airflow and reduce heat stress. - Leaf Feeding
Spray tomato bushes with calcium fertilizer early in the morning or late in the evening to help the plants cope with heat stress and continue healthy growth.
By following these simple steps, you can protect your tomatoes from extreme summer heat and ensure a healthy, abundant harvest!
