Growing tomatoes takes a lot of work, but the first juicy fruit makes it worthwhile. One of the most common problems is a tomato plant wilting.
Tomato plants like it hot, but even for these heat lovers there can be too much of a good thing. If gardeners notice their tomato plants are wilting in the heat it’s time to take some proactive steps to save the plants.
Speaking exclusively to Express.co.uk, Gene Caballero, co-founder of GreenPal has shared how Britons can revive the tomato plants in their garden after the sudden heatwave the UK has been experiencing.
The expert said: “I’ve seen firsthand the challenges that extreme weather conditions can bring to our gardens, especially to tomato plants which can be particularly sensitive to heat.
“From what I’ve learned, the key to reviving and maintaining heat-stressed tomato plants is consistency in care.

“By monitoring and providing their basic needs, you can see them bounce back and even flourish after a period of extreme heat. Here are my tips to help revive tomato plants after they’ve suffered through extremely hot weather.”
1. Water deeply, but gently
It may be obvious, but the “most immediate need of heat-stressed tomato plants” is water, claimed Gene.
He said: “It’s essential to give them a deep watering early in the morning or late in the evening to avoid further stressing the plants.
“This ensures the roots can absorb the moisture without the hot sun evaporating it away too quickly.”

2. Use mulch
To help the soil retain moisture and protect it from direct sun exposure, apply a layer of organic mulch, like straw or shredded leaves, around the base of tomato plants.
This not only “keeps the roots cooler” but also “prevents soil-borne diseases” from splashing onto the leaves.
3. Avoid fertilising
After a heatwave, tomato plants will be stressed so refrain from adding fertiliser, which can “further stress the plant”.
Instead, ensure it gets “adequate water” and consider applying a foliar spray with seaweed extract to provide some “immediate relief and nutrients”.
4. Prune sparingly
While it might be tempting to remove the damaged foliage right away, be gentle and “only prune” severely wilted or sunburned leaves. Gardeners need to remember that the plant needs its leaves for photosynthesis.
5. Check for pests
Stressed plants can be “more susceptible” to pests and diseases. After extreme heat, regularly inspect plants for any signs of infestations and treat them promptly.
6. Consistent care
Ensure a consistent watering schedule is maintained. The expert warned: “Inconsistent watering, especially after a heatwave, can lead to problems like blossom end rot.”
