What to do with Tomato Plants in Extreme Heat

The heat of summer can be tough on tomato plants. Extreme heat can cause blossom drop, sunscald, or even wilt the plant. If you live in an area with hot summers, there are several things you can do to help your tomato plants survive and thrive.

Provide Adequate Water

Tomato plants need consistent moisture to thrive, especially during hot weather. Water your plants deeply to help them stay hydrated. It's best to water early in the morning or late in the evening when the sun is not as intense. Avoid getting the leaves wet, as this can lead to sunscald or promote the growth of fungal diseases.

Shade Your Plants

If your tomato plants are in an area that receives direct sunlight during the hottest part of the day, consider shading them. You can use temporary shade cloth or even an umbrella to protect the plants from the harsh sun. Alternatively, you can plant your tomatoes in an area that receives some shade during the day.

Mulch Your Plants

Mulching your tomato plants can help keep the soil cooler and retain moisture. A layer of organic mulch, such as straw or hay, can help insulate the soil and protect the roots from heat. Avoid using black plastic as a weed barrier, as it can trap heat and make the soil too hot for your plants.

Prune Your Plants

Tomato plants can get out of control quickly, especially in hot weather when they grow rapidly. Pruning your plants can help control their growth and keep them from becoming too leggy. Remove any suckers that develop between the main stem and the branches. This will help the plant channel its energy into producing fruit rather than foliage.

Harvest Your Tomatoes

When temperatures rise above 90°F, your tomatoes may stop growing and ripening. To prevent your fruit from becoming overripe or splitting, be sure to harvest your tomatoes as soon as they are ripe. Don't leave them on the plant for too long, as they could become overripe and unpalatable.

Conclusion

With a little extra care, you can help your tomato plants survive the extreme heat of summer. Providing adequate water, shading your plants, mulching, pruning, and harvesting your fruit are all crucial steps in helping your plants thrive during hot weather. By following these tips, you can enjoy a bountiful harvest of delicious, homegrown tomatoes all summer long.
