How to Protect Tomatoes from Heatwaves: 4 Easy Steps to Keep Your Plants Healthy

By Amy Grant | Contributions from Amy Draiss | Published 14 hours ago


Tomatoes are one of the most-loved crops in the home garden—juicy, flavorful, and incredibly satisfying to grow. But they’re also surprisingly sensitive, especially when temperatures start to climb. Despite being sun-loving plants, tomatoes can suffer serious stress during heatwaves, especially during crucial growth stages like flowering and fruit development.

So, do tomatoes need protection from the heat? Absolutely. And knowing when and how to step in can make all the difference between a strong harvest and a stalled one.

Let’s dive into why heat is a problem and how you can help your tomato plants thrive—even in the hottest part of the summer.


Why Tomatoes Struggle in Extreme Heat

Tomato plants will be revived after hot weather by following six essential  tips | Express.co.uk

Tomatoes grow best in temperatures around 75–80°F (24–27°C). They can tolerate brief periods of up to 90°F (32°C), but once temps hit 90–95°F (32–35°C) and stay there for a while—especially if it’s humid—you might start seeing problems.

Here’s what heat stress can do to tomatoes:

  • Stops pollination: The flower structure breaks down, and pollen can’t make it to the stigma.
  • Flower drop: High temps can cause flowers to fall off before they even get the chance to pollinate.
  • Scalded fruit: When fruit is exposed during heat spikes, it can get sunburned.
  • Wilted leaves: While this is sometimes just a survival response, constant wilting means the plant is struggling.

The good news? There are things you can do—whether a heatwave is on the horizon or your tomatoes are already feeling the burn.


How to Protect Tomato Plants from Heat

11 Tips for Growing Terrific Tomatoes in Pots

1. Grow Heat-Tolerant Tomato Varieties

The Best Tomatoes to Grow by Zone – Mother Earth News

Some tomatoes just handle the heat better than others. Look for heat-tolerant or early-ripening varieties that finish their growth before peak summer temps roll in. Most of these are determinate types that produce fruit all at once.

Here are a few great options:

  • ‘Heatmaster’
  • ‘Phoenix’
  • ‘Dixie Red’
  • ‘Big Beef’
  • ‘Black Cherry’ (tasty and beautiful)
  • ‘Early Girl’ – available in the Gardening Know How Shop, this variety matures about 60 days after transplant and resists common diseases.
  • ‘Arkansas Traveler’ – an heirloom from Burpee, also resistant to disease and well-suited to tough climates.

Pro Tip: Try planting in a spot that gets morning sun and afternoon shade to avoid the harshest rays while still meeting their 6–8 hour sun requirement.


2. Provide Shade During Peak Heat

If your tomatoes are exposed to full sun all day, it’s a good idea to give them a break during the hottest hours.

You can create shade using:

  • Shade cloth (check Walmart or Wayfair for affordable options)
  • Old sheets
  • Shower curtains (yep, it works!)

Drape your shade cover over stakes or a string line to keep air flowing underneath. Cover the plants around midday, and remove the shade once temperatures drop below 90°F (32°C).


3. Water Early, Water Deeply

When it’s hot, tomatoes need water—and lots of it. Here’s how to keep them hydrated:

  • Water early in the morning to minimize evaporation.
  • Always water at the base of the plant to avoid fungal issues.
  • Aim for at least 1 inch (2.5 cm) of water daily.
  • During extreme heat, you might need to water 2–3 times a day.

Check soil moisture by sticking your finger 2–3 inches into the soil. If it’s dry, it’s time to water. And don’t panic if the plant looks wilted in the heat—it often perks up as temperatures fall.


4. Harvest Early If Necessary

If a major heatwave is coming and your plants have ripening fruit, consider harvesting early.

Tomatoes don’t need to ripen on the vine. As long as they’ve reached the mature green stage, you can pick them and let them ripen indoors on a windowsill, kitchen counter, or in a paper bag or box stored in a cool, dry area.

Use a clean, sharp tool like the Garden Guru Hori Hori Knife (available in the Gardening Know How Shop) to avoid damaging the plant when cutting fruit off.


How to Help Tomatoes Recover After a Heatwave

Even if your tomatoes have already taken a hit, there’s still hope. Here’s how to help them bounce back:

  • Keep watering deeply in the mornings—but avoid watering in the middle of the day.
  • Hold off on fertilizing for a bit. Let the plant recover first to avoid more stress.
  • Keep shading them during hot afternoons—even after the worst of the heat is over.
  • Trim yellow or dead leaves to prevent disease and pest problems.
  • Harvest what you can if the plant seems too stressed to bounce back, and ripen fruits indoors.

FAQs: Tomato Heat Protection

How can I protect container-grown tomatoes from heat?

If your tomatoes are in containers, try placing them on rolling casters so you can easily move them into partial shade during the hottest part of the day. Containers dry out faster, so check the soil several times a day and water thoroughly.

Should I fertilize tomatoes during a heatwave?

No. Avoid fertilizing during extreme heat, as it can stress the plant further and even lead to leaf burn. Wait until temperatures normalize and the plant starts showing signs of recovery.

Can I use mulch to keep tomato roots cool?

Absolutely. A thick layer of mulch helps conserve moisture, reduce soil temperature, and protect roots. Just don’t let it touch the base of the plant directly.


Final Thoughts: Beat the Heat and Grow Better Tomatoes

Tomatoes may love the sun, but too much of a good thing can hurt them. Long stretches of high heat can stunt growth, stop pollination, and ruin your harvest if you’re not careful. Thankfully, with the right techniques—choosing heat-tolerant varieties, creating shade, watering properly, and harvesting early when needed—you can still grow an amazing tomato crop even during the most sizzling days of summer.

Keep a close eye on the forecast, and be ready to jump in with extra care when heatwaves hit. Your tomatoes will thank you with juicy, sun-kissed fruit later on.
