This type of leaf curl is a response to environmental issues almost 100% of the time. If your plant is being exposed to too much sun, too hot of temperatures, too much wind, or a lack of water, the leaves will curl up to protect the plant from the sun and heat.
Leaf curl can also be caused by a number of other factors, such as poor air circulation, poor soil moisture, and too little water. The best way to prevent this problem is to keep the soil moist and allow the plants to dry out between waterings.

Can overwatering cause tomato leaves to curl?
As overwatered tomato plants mature and begin to set fruit, the topmost leaves curl inward and upward. The leaves are either firm or brittle. The symptoms are not indicative of the sudden death of the plant. Instead, it’s a sign that the plants are in good health and are ready to harvest.
Can tomato plants recover from leaf curl?
The other part showed no curl at all. This part was removed because it was too close to the ground. The plant will recover if the other parts are removed, but it will not recover as quickly as the first part.
Should I remove curled tomato leaves?
When tomato leaf curling is caused by a viral infection, removal of the virus from the plant is necessary to prevent the disease from spreading to other plants. Viral infection of tomato leaves is caused by a virus that infects the leaf cells. The virus is transmitted from plant to plant by direct contact with infected leaf tissue.
Tomato leaves can be infected with a variety of viruses, including tomato mosaic virus (MV) and tomato cytomegalovirus (CMV). The most common viral pathogen in tomato is CMV, which is responsible for the majority of disease in tomatoes. Other viruses that can infect tomato plants include tomato rhamnosus, tomato klebsiella, and papaver somniferum.
In addition, some viruses have been isolated from tomato fruit, such as tomato lyophilized virus. Viruses can also be present in the soil, but the presence of these viruses does not necessarily indicate that they are the cause of a tomato disease.
Will too much fertilizer make tomato leaves curl?
Tomato leaf curling could also be an indication of too much fertilizer. When it comes to over-fertilizing, the lower leaves of your tomatoes roll upward until the side edges touch. The leaves become thick and waxy after being affected. This is a sign that the soil is too rich in nutrients.
If your tomato leaf curl is caused by too little fertilizer, you may need to increase the amount of fertilizer applied to your soil. If you have a soil test done, it will tell you if you need more or less fertilizer to correct the problem.
How do I know if I overwatered my tomato plants?
Overwatered plants may have wilted or yellowed stems and leaves, or the leaves might develop bumps and blisters or fall off entirely if plants continue to get too much water. Once the case is severe enough, it is a good idea to look at the soil around the plant.
If you notice that your plant is wilting, you may need to water it more often than usual. This is especially true if you have a large number of plants in a small pot. It’s also a good idea to check your plants regularly to make sure that they’re getting enough water and nutrients.
How often should I water my tomato plants?
Water newly planted tomatoes well to make sure soil is moist and ideal for growing. Early in the growing season, watering plants daily in the morning. As temperatures increase, you might need to water tomato plants twice a day. Tomatoes require 1-2 inches of water per week. Plant tomatoes in well-drained soil.
Tomato plants need a good amount of moisture to grow well. Plant in a sunny location, away from the heat and direct sunlight. Water tomatoes once a week or as needed to keep plants healthy and happy.
What do Underwatered tomato plants look like?
Tomato plants that are temporarily water-stressed will have wilted leaves that are still green. Tomato plants that are regularly or chronically water stressed conserve water in their roots and stems while allowing leaves to yellow, usually starting with the lower leaves.
Watering tomato plants with fertilizers will not increase the amount of nitrogen in the soil, but it will improve the quality of the plant’s root system. If you fertilize your tomato plant with a high-nitrogen fertilizer, you may need to water it more often.
What do curling leaves mean?
When leaves curl or ‘cup’ at the tips and the margins, the plant is trying to retain moisture. Downward curling is a good indicator of over watering or waterlogging. If the leaves turn yellow, it’s a sign that the soil is too dry. If they turn brown, they’re dehydrated and need to be re-hydrated.
The plant may also be suffering from root rot, which is a fungus that causes the roots to rot. It can be treated with a fungicide to prevent the fungus from spreading to other plants.
Can tomato plants get too much sun?
Tomato sunscald is a problem caused by growing conditions – specifically intense, direct sunlight for extended periods during very hot weather. Tomatoes turn yellow and brown when exposed to excessive sunlight.
Sunburn is the most common cause of sunburn in the U.S. It can occur from direct exposure to the sun, such as from sunbathing or sunlounging, or from the use of sunscreen, tanning beds, and other sun-protective devices.
In addition, sun exposure during pregnancy can increase the risk of developing skin cancer.
What do Overwatered tomato leaves look like?
A tomato plant that is overwatered will look dull and depressed. On top of this, it might have yellowing leaves that’ll eventually turn brown around the edges. The fruits of an overwatered tomato are small and flat. If you notice that your tomatoes are wilting, you can check to see if your plant is overwatering.
You can do this by placing a small amount of water on the plant and letting it sit for a few minutes. If the water doesn’t evaporate, then you know that the tomato has been over watered.
