Can tomato plants get too much sun? It’s vital to insulate tomatoes from extreme heat when growing them. There are various methods to achieve this, however, some are more efficient than others. Even in the hottest weather, these tips will help you keep your tomato plants healthy and full of life.
How heat affects tomato plants?
Excessive heat stress affects the rate of pollination of tomato plants. Heat causes fewer tomatoes to grow. Heat stress also affected the amount of lycopene, which led to too much evaporation and bad fruit quality.
How do Tomato Plants React to Heat?
As gardeners, we are all aware that varied plants require various situations to flourish at their optimum. Other people enjoy it hot, some people cool, other people wet, and some people dry. What transpires, however, when the environment that our plants are accustomed to unexpected changes?
High temperatures are hazardous for tomato plants. Even while a few hours of heat stress won’t kill your plants, it could have a detrimental influence on how much fruit they produce.
The plant will also avoid fruit production to survive the heat wave. You may have an abundance of green tomatoes that never develop. If the heat wave continues, tomato plant leaves may droop, dry, and fall off. This prevents the plant from photosynthesizing, which leaves the fruits vulnerable to sunscald.

What temperature is too hot for tomato plants?
Can tomatoes get too much sun? Contrary to what many people think, tomatoes do not like heat. The best range is between 75 and 95 for tomato plants. When the temperature is too high during the day (above 85 degrees) or at night (above 65 degrees), the blooms on many crops, like tomatoes and peppers, may fall off (over 70 degrees).
Some tips to protect your tomato plants from excessive heat
As temperatures rise, protect tomato plants from excessive heat. How can you protect tomato plants from the heat?
We’ll look at some of the finest tips for sheltering your tomato plants from high heat stress.
1) Choosing a heat-resistant tomatoes variety
Tomato heat tolerance varies. Some are heat-resistant. Location matters too. In warmer climates, you must take extra steps to water and shade your tomatoes. Heat-resistant tomato varieties:
- Apache: Produces small, pear-shaped fruit under extreme temps.
- Heatwave: This cultivar thrives in hot climates. It produces oblong, red fruit.
- Sunmaster: Round, large tomatoes are another good choice for hot climates.
- Solar Set: This heat-tolerant cultivar produces small, oval fruit.
- Tropical: This cultivar thrives in warm climates. It produces spherical, little fruit.
When choosing a heat-tolerant tomato cultivar, consider your needs and growing conditions.
2) Location while Placing tomato plants
Tomatoes’ heat tolerance may depend on their location. Tomatoes like warmer conditions. High temperatures may damage fruits. To avoid this, grow tomatoes in a cool spot. One way to achieve this is to choose a sunny yet shaded spot. Raised beds or trellises may keep tomatoes off the ground and out of the sun.
In summer, you may need to take extra steps to safeguard your tomatoes. Use a light-colored towel or a fan to cool them throughout the day. With care, tomatoes may thrive in hot climes. Choose a cool area and protect them from the heat if needed.
3) Provide enough Shade to plants
Tomatoes benefit from shade in several ways. It may protect plants from the sun’s glare, which might burn their leaves. Tomatoes like chilly, moist soil around their plants.
Tomato plants need shade based on local weather and temperature. In hot, dry summers, tomato plants may benefit from midday shade. If you live in a cooler climate with milder summers, your tomato plants should be OK in full sun.
Experiment to see what works best for your plants. If your tomato plants are struggling in direct sunlight, try shading them to see if it helps. If you can’t find a shady spot for your plants, you can create shade. Burlap or a light-colored fabric should be used to shade plants throughout the day. Remove the shade during cooler hours to give the plants sunlight.
4) Water tomatoes plants properly
As temperatures climb, keep tomato plants watered. Tomatoes require regular watering, but more in warmer weather. But don’t overwater, heat stress may limit plant growth and yield.
Hot-weather tomato watering tips:
- Check the soil before watering: To check soil moisture, touch it. If so, water.
- Morning water: Before the sun becomes too scorching, water your plants in the morning.
- Avoid watering leaves: Sun-baked water on leaves may cause leaf spots.
- Drip or soaker hose: These methods reduce evaporation and increase plant root watering.
5) Mulch Plant Areas
Hot weather requires tomato plant protection. Mulching works best. Mulching keeps soil cool and moist, which tomato plants need. It prevents weeds and soil erosion. Organic mulch like leaves or straw works best.
Mulching tomatoes in hot weather has three benefits:
- Mulching keeps plant roots cool and wet, protecting them from the sun.
- Mulching protects plants from drying out.
- Weeds, which compete with plants for water and nutrients, are prevented by mulching.
6. Avoid overfertilizing
Too much fertilizer may stress tomatoes and make them more vulnerable to heat damage. Fertilize moderately and follow package recommendations. When temps rise, fertilizing tomato plants might seem enticing. In hot temperatures, resist the impulse.
Fertilizing in hot weather may hurt plants. Tomatoes do not need a lot of fertilizer, and in fact, too much fertilizer might stress plants and increase their sensitivity to heat damage. Fertilize tomato plants while it’s chilly. This will keep them healthy and provide plenty of delicious fruits for you.
7. Pests and diseases
Pests and diseases may affect tomato plants year-round, but excessive heat makes them worse. When it’s hot, watch your tomato plants. Heat waves stress tomato plants, making them more susceptible to pests and diseases.
Healthy plants reject most pests and illnesses. Heat-stressed plants lose this resistance and become more vulnerable to outside intervention. Untreated pests and illnesses may destroy your tomato crop. Heat stress slows plant recovery from pests and diseases.
8. Ripe tomatoes indoor
Consistent heat may prevent tomatoes from ripening. If your tomato plants have ceased generating red pigments and the fruits are merely becoming orange or not ripening, you may remove them and ripen them inside in a warm area. This prevents fruit from waste and maximizes ripening.
Last verdict
Tomato plants wilt in the heat. Heat can cause fruit to grow too quickly or stop setting fruit altogether. Gardeners can help their tomato plants grow even when it’s hot by choosing a type that can handle the heat. Putting them in the right spot. Giving them enough shade, and giving them the right amount of water.
