What Causes Curling Leaves on Tomato Plants and How to Fix Them
Many home gardeners keep tomato plants, but sometimes they may see their leaves curling. If you know what's causing it, you can fix your plant's health problems. But it's still troubling.
1. The Impact on the Environment
Environmental stress is a typical reason why tomato plants' leaves curl. Rapid changes in humidity, temperature, or wind speed may kill tomato plants. To protect itself from dry winds or high temperatures, the plant may curl its leaves inward to retain water.
A possible solution is to mulch the soil around your tomato plants to help keep them wet and to water them well, particularly in hot weather. We recommend providing shade throughout the peak hours of the day to further alleviate heat stress.
2. Whether to Water Too Much or Too Little
Either too much or not enough water can cause curling leaves. Overwatering plants may lead to root suffocation, which in turn causes the leaves to droop. However, submerged plants will curl their leaves to prevent excessive water loss.
Regularly checking the soil moisture is the solution. It is ideal for the soil to be damp but not soaked. When you water, make sure the top inch dries up completely. Ensure that the garden beds or containers you use have enough drainage.
3. Inadequate nutrient intake
In order to thrive, tomato plants need a wide range of nutrients. The curled leaves of your tomato plant might be an indication that it is deficient in essential minerals like calcium, potassium, or nitrogen. Along with the curling, you can notice the leaves browning or yellowing.
A balanced fertilizer will provide your tomato plants all the nutrients they need; therefore, that's the solution. If you want to know which nutrients your soil is lacking, you can do a soil test. You can then adjust your fertilizer schedule accordingly.
4. Insects and Other Pests Aphids, whiteflies, and spider mites are just a few of the pests that may feed on tomato plant sap, which in turn causes leaf curling. These microscopic pests prefer to live on the undersides of leaves and, if left unattended, may gradually sap a plant's strength.
Answer: Keep an eye out for pests by checking your tomato plants often. Neem oil or insecticidal soap may help control pests. Bringing in beneficial insects, such as ladybugs, to help manage pest numbers is a natural way to handle the problem.
5. Damage from herbicides
Unwanted leaf curling and twisting may occur in tomato plants as a result of accidental pesticide exposure. One typical source of this kind of harm is herbicide drift from neighboring gardens or lawns. Herbicides in mulch or compost, even in trace levels, may harm tomato plants.
Using herbicides in close proximity to tomato plants requires extra caution. There isn't much you can do to fix pesticide damage, but giving the plant the TLC it needs can help it bounce back eventually.
6. The TYLCV disease, which affects tomatoes

Leaf curling, stunted development, and yellowing are symptoms of this virus, which is carried by whiteflies. There is currently no way to treat TYLCV infections in plants.
To stop the virus from spreading to healthy plants, you should remove and kill the afflicted ones. The application of beneficial insects, yellow sticky traps, or insecticidal soap may assist control whitefly numbers and prevent future transmission.
In conclusion
A variety of problems, from mild environmental stress to more severe viral infections, may cause tomato leaves to curl. Tomato plants may be kept healthy and free of curling by keeping a close eye on them and finding out why they are curled.
You may achieve healthy plants and an abundant yield by taking preventative measures with your tomato care to reduce the impact of pests and other stresses.
