You will want to look at the plant’s coloration, leaves, and stem to help weed out the many reasons your tomato leaves are curling. - Source: Internet
- The best thing is to do stop watering your tomato plants. Wait for the plants to soak up as much as possible. It typically sorts itself out, and in the future, make sure you improve the drainage of your garden beds. - Source: Internet
- Twisted or curled leaves on tomato plants can be caused by environmental stress, exposure to chemicals, or biological factors. While curling leaves do not necessarily kill the plant, determining the cause, or combination of causes, for the curling leaves as early as possible is crucial. Because it is often a gradual process, the quicker you take corrective action, the better. - Source: Internet
- Tomatoes that have not been properly hardened off, or planted too early when the weather was still too cool, can suffer from leaf curl. It usually starts with the lower leaves curling upwards, then rolling inwards lengthwise. The leaves also become thick and leathery but usually remain green. - Source: Internet
- Yellow, cupped, or curled-up leaves can all seem problematic while growing your own tomatoes, but it doesn’t always mean that your plant will fail. In fact, this easy-to-grow plant is hard to kill off, and can easily be fixed if you notice curling leaves or a yellow-hue taking over the foliage. These are the common causes of curling, yellow tomato leaves and exactly how to fix them. - Source: Internet
- The second problem is overwatering. If you water too often or with too much water, the roots can start to rot. As a result, the water supply to the leaves will be interrupted and the leaves may curl down. This is very similar to underwatering because in both cases, the roots are not doing their job. - Source: Internet
- Many home-gardeners pride themselves on the success and health of their tomato plants. When something out of the ordinary happens, it can be heartbreaking. And finding that your precious tomatoes have tomato leaf curl can be one of those heartbreaking moments. - Source: Internet
- If the leaves on your tomato plant have a downward curl, then it could be because of a condition called root rot. When roots are inundated with water they respond by constricting to protect themselves and the plant from decay. Constricted roots take in less water and nutrients which, in turn, can cause leaves to curl downward. If the roots continue to sit in soggy soil they will begin to rot. - Source: Internet
- Because curly top virus is a systemic disease, it will eventually kill the plant. There is no treatment. Instead, prevent infection by controlling leafhopper populations. Learn how to treat leafhoppers organically in this helpful article. - Source: Internet
- – caused by Alternaria tomatophila or Alternaria solani. Early blight spreads more rapidly in damp conditions, such as after rainy weather, watering your garden, or heavy morning dew. Late Blight – caused by the fungus Phytophthora infestans.

- If you used manure or compost from a third-party source and the leaves of your tomato plants become cupped, or in any other way distorted, the reason might be residue from herbicides such as aminopyralid or clopyralid, the active ingredients in weed killers used by farmers. These chemicals remain on treated hay and hay products, grass clippings, manure, and compost for many months. Cows and horses feeding on that hay then pass it on via the manure. - Source: Internet
- Another cause of leaf roll is insect pests. Some pests, like the pickleworm, curl leaves to create a protective shelter in which they can hide, lay eggs, or pupate. Other pests, like broad mites, inject toxins into leaves causing the tissue to curl or become distorted. Broad mites are the smallest species of mites and are almost invisible to the naked eye. - Source: Internet
- Another reason that your plants might have leaf curling is that you need to give your plants more water. Tomato plants need ample water; in general, tomato plants need one to two inches of water per week. Container-grown tomato plants need more water than that. - Source: Internet
- To combat a moderate broad mite infestation, you can use a sulfur-based miticide. Read the label instructions carefully, as some tomato cultivars cannot tolerate treatment with sulfur. Organic alternatives to miticides are horticultural oils and insecticidal soaps. - Source: Internet
- If you add too much nitrogen to your soil, then you might notice leaf curling as well. After the leaves curl, they might become thicker and a dark green color. You’ll notice these symptoms most often on heavily pruned tomato plants. - Source: Internet

- In some percentage of cases, the sun and heat can still damage tomato leaves. If you want to help your tomato install a shade net over it. The netting should filter at least 50% of the sun’s rays. When the heat subsides, remove the screen immediately so the tomato gets enough light. - Source: Internet
- Stress from unsuitable growing conditions, too little water, lack of nutrients, and Tomato yellow leaf curl virus are the main reasons for tomato leaves curling. To fix curled leaves, protect the tomato from the scorching sun and heat, also water it when the soil dries out to 1 inch. In addition, fertilize the plant at least twice a season and treat it for pests. - Source: Internet
- While less common than the above causes, micronutrient deficiency can be a source of leaf curl. Micronutrients like molybdenum and boron can be depleted over time. The deficiency is also sometimes seen in lesser quality soils. - Source: Internet
- Leaves that curl up are very common and won’t hurt your tomato plant at all. 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 themselves. The leaves are like mini solar panels, so when the plant has a sufficient amount of sunlight, they close in order to prevent sunburn on the leaves. This type of curl will go back to normal as soon as the environmental problem goes away. - Source: Internet
- Tomatoes are an heirloom gardener’s best friend. However, there is a world of diseases, deficiencies, and pests to deal with when growing them. Tomato leaf problems are the most frequent in the garden, especially if you are growing non-heirloom varieties. Today, we are going to discuss the handful of tomato issues that can be identified simply by looking at leaf curl on the plants. Leaf curl is not always a bad thing, so we will look at what it means on each part of the plant. - Source: Internet
- To remedy this, water the tomato as I recommended above. If it hasn’t fructified yet, you can transplant it into clean, well-drained soil, removing any rotten tissue. Or water it with fungicide against root rot. - Source: Internet
- – this will protect tomato plants from intense sunlight, and can reduce their temperature by up to 10 degrees Fahrenheit. Keep plants watered – feel the soil with your fingers, and water your tomato plants if the soil feels dry. Check often in hot, dry weather. Consider a drip irrigation system on a timer. - Source: Internet
- The second is a general lack of soil nutrition. In this case, the tomato leaves may not only curl but also turn yellow. In addition, the plant will develop noticeably slower and fruit poorly. - Source: Internet
- We have received several calls recently reporting observations of leaf curling on tomatoes. Although several factors (disease, insect, herbicide, environmental stress etc.) could cause leaf curling, in late spring and early summer, we notice the majority of the leaf curling is caused by physiological factors that in general do not directly affect tomato yield and fruit quality. - Source: Internet
- Growing tomato plants can be tricky, especially if you don’t pay attention to your plants regularly. You never want to miss something like your tomato leaves curling up that could indicate a problem.

- The second case is when there is too much sun. The tomato prefers direct sun all day. But in midsummer, the sun is very intense, and if you live in the south, the plant can get stress or even sunburn. Very often heat and sun work together and can greatly affect the appearance of the tomato. - Source: Internet
- Tomato mosaic virus is transmitted by aphids. In addition to curling, the leaves become mottled, and new leaflets are small. Infected fruit is brown inside. - Source: Internet

- Herbicide drift damage will depend on the amount of exposure. The damaged leaves can be removed, and new growth may not be affected. If entire tomato plants have been affected, remove and destroy them. - Source: Internet
- Fertilizer plays an exceptional role in the formation of large and juicy tomato fruits. Regular soil is not too nutritious for growing tomatoes so fertilizer is definitely needed. But improper fertilization can lead to problems. - Source: Internet
- Once the herbicide drift has occurred, there is nothing to be done. Depending on the severity of the herbicide damage, the plant may recover and the new growth may look normal. If the new growth continues to show herbicide damage, which in addition to curling leaves might include white and splitting stems and deformed fruit, you will unfortunately have to pull the plants. - Source: Internet
- To solve this problem, add good quality fresh compost to the soil. One bucket under each bush is enough to improve the condition of your tomatoes. Spread some of the compost on the surface around the plant to prevent the soil from drying out quickly and overheating. - Source: Internet
- Tomato plants are highly sensitive to herbicide damage. If the tomato leaves are curling downwards and growing in a twisted way, they might have been exposed to drifting herbicides—not necessarily from your own use but it could be from neighbors treating their lawn, or from farm fields in the area. When glyphosate or 2,4-D, dicamba, and other hormone-type herbicides are being sprayed, even wind speed of five miles per hour can lead to herbicide drift. - Source: Internet
- The most common virus among tomatoes is the Tomato yellow leaf curl virus. Symptoms of this disease show upward curling of the leaves. Usually, the leaf deformation is very severe and noticeably different from other causes of curl. - Source: Internet
- Curly top virus is the most common of the tomato leaf viruses. It is observed in new leaf growth which will appear twisted, spindly, or curly. Growth may be stunted, or it may try to produce additional side shoots or suckers to compensate for the diseased tips. - Source: Internet
- Pruning stresses out your tomato plant, but it’s essential for taking care of your plant. The leaves on your plants are how they make food, converting the sunlight into energy. So, if you remove too many leaves, then your plant will struggle. - Source: Internet
- The lack of nutrients like boron is a situation that can cause the tomato leaves to curl. But this is not a common issue and it’s not a serious one either. Adding a little bit of compost or fertilizer to your plants will solve this problem. - Source: Internet
- Hot and dry conditions during summer months can create drought conditions, these conditions can cause your tomato leaves to curl. Tomato plants will curl/roll their leaves to help conserve water as a type of self-preservation. Too Much Water - Source: Internet
- A healthy tomato plant (like the image above) is a nice shade of green, the shade can vary depending on your variety. The leaves should be open but may appear slightly droopy (the droop downward is normal especially with longer leaves). You should be able to see healthy new growth and flowers present. - Source: Internet
- Another cause of leaf curl can be excessive pruning. Removing too many branches (and therefore leaves) decreases the plant’s ability to convert sunlight into energy. This stressor can result in leaf curl, yellow leaves, stunted growth, and lower fruit yield. - Source: Internet
- If the bright sun and heat last long, then shade the tomato only from the sun in the middle of the day. That is, the tomato should receive direct sunlight in the morning and evening. Because staying in full shade for a long time will also lead to negative effects. - Source: Internet
- The Tomato yellow leaf curl virus is spread by insects, namely the whitefly. Other insects hardly ever spread the disease. It is also possible that the virus can be transmitted by generative means. - Source: Internet

- Tomato yellow leaf curl virus can cause both upward and downward leaf curling. Young leaves, in particular, will yellow in between the veins. Growth will be stunted, and you may also notice that flowers and fruit either do not develop or they drop off. The virus is spread by Silverleaf whiteflies. You can learn more about this whiteflies and how to get rid of them in this helpful article. - Source: Internet
- Tomato plants are very sensitive to herbicides. Exposure will produce leaves that bend downward while the edges curl upward. New growth, which is affected first, will appear twisted or deformed. - Source: Internet
- In this case, the leaves on which the herbicide hit will curl inward and shrivel. Their color becomes pale and then turns yellow. The peculiarity of such curling is that not all leaves are curled but only the damaged part. - Source: Internet
- Aphids are another common pest that attacks tomato plants. They feed on the sap found in stems and leaves. These small but destructive insects stunt plant growth, cause leaves to curl and reduce fruit yield. You can learn more about them and how to treat them organically in this helpful article. - Source: Internet
- To solve the problem of lack of water, you need to constantly monitor the moisture of the soil. Do this with a moisture meter or with your fingers. If the soil is more than 1 inch dry, you need to water the tomato. Don’t be fooled by the advice to stick to a schedule, the weather is constantly changing and the tomato’s watering needs change accordingly. The exception to this is tomatoes growing in the greenhouse. - Source: Internet
- Lower, and therefore older, leaves will experience this first followed by younger leaves. As a result, curled leaves will absorb less heat and slow down the transpiration rate, conserving moisture. (Transpiration is the movement of water throughout the plant. Water transpires or exits via stomates on the leaves.) - Source: Internet
- I live and garden in central California. The leaves on my Roma tomato plant are curling. It is in a large pot and placed in sunshine. What am I doing wrong? - Source: Internet

- Excessive nitrogen can also cause leaf curling, and the rolled leaves are often thicker and become dark green. The symptom is often noticed on heavily pruned tomato plants and plants that lose growing points. In Figure 1, the tomato plant was pruned and trellised to be grown with two main leader system. One part of the plant showed significant leaf curl because the growing point of this part of the plant was accidentally removed. As long as there are other growing points remaining, the plant can recover, and the leaf curling will only be a temporary observation. - Source: Internet

This occurs because tomato roots are somewhat delicate and relocating a plant to a new spot in the garden causes them stress. Shock can also occur if seedlings are planted outside before soil temperatures are consistently warm. Transplant shock is perfectly normal and should resolve in a matter of days. - Source: Internet
- First of all, this can happen in extreme heat. Tomatoes are heat-loving plants, but temperatures above 90°F (32°C) can cause stress and cause the leaves to curl up. This happens because the roots are unable to put enough water into the leaves even if the ground is moist. By curling (folding) the leaves, the tomato reduces the area of moisture evaporation, thereby avoiding the desiccation of the leaves. - Source: Internet
- Another cause of environmental stress is a windy situation. This causes the water to evaporate from the leaves. And the leaves curl up to protect themselves. - Source: Internet

Minimally infested plants can possibly be saved, remove the damaged leaves and spray your plant with organic insecticidal soap. - Source: Internet
- Heat Heat can cause tomato leaves to curl up as a way of reducing the surface area exposed to the sun, which helps to minimise the amount of moisture lost through the foliage. While watering may seem like the obvious fix to a plant that has had too much sun, it could actually do more harm than good. According to Next Level Gardening, this is because leaf curl is generally not caused by a lack of water in the soil, but by the plant losing more water through the leaves than it can absorb from the roots. Once a heatwave passes, the problem should fix itself so there is no need to water your tomatoes more excessively. However, in prolonged periods of hot weather, it is best to use shade cloth to help keep the plant from dropping its flowers and stop the leaves from curling. - Source: Internet

To avoid this, leave the soil on the root ball when you transplant. sun exposure of roots – it is common to take tomato transplants out of their tray and leave them in the sun while digging holes for them. On a hot, dry day, this will soon cause root damage. Instead, leave each transplant in the tray until it is time to transplant it. - Source: Internet
- If the number of damaged leaves is not high, the plant will resume after a while. However, I would not recommend eating the fruits of such a tomato. The curled leaves will shrivel up and fall off. - Source: Internet
- Tomato mosaic virus, as well as cucumber mosaic virus and tobacco mosaic virus, can negatively impact tomato crops. Younger plants will be stunted, and their leaves will curl upwards. In addition, leaves will be mottled and wilting. The fruit will look puckered and brown inside. - Source: Internet
- The first thing to note here is the excessive amount of nitrogen in the soil. This often happens when using fertilizers with a high proportion of nitrogen about other micronutrients. As a result, the leaves start to grow more intensively and curl down. - Source: Internet
- The most common causes of upward leaf curl are environmental stressors. Leaves act as solar panels to collect energy for the plant. When conditions are too dry, too hot, or too windy, the leaves will curl upwards to reduce their surface area. This is sometimes referred to as physiological leaf roll. - Source: Internet
- Another common cause of tomato leaf curl is herbicides. Perhaps you wanted to get rid of weeds in your beds and accidentally sprayed the tomato. This can happen if there are a lot of tomatoes and you can’t always be careful enough with herbicides. - Source: Internet
