80 Tips for What Causes Leaves To Curl In Tomatoes | Tomato Plant Leaf Curl Remedy

• 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
• When you see the tomato leaf curl, don’t panic. It’s like when you have a bit of a cold or a belly ache. While it could indicate a more serious problem, it’s usually not a big deal and easily remedied. - Source: Internet
• There are really no home remedies when treating leaf curl. The only home remedy I can think of is when the tomato leaf curl is caused by pests such as aphids. And the home remedy for them include a powerful stream of water to knock them off the plant, organic neem oil, and companion planting. As for other reasons that cause leaf curl such as overwatering, high temperature, excessive fertilizer, etc. you just need to determine the cause and adjust from there. - Source: Internet
• Tomatoes require constant moisture rather than fluctuating periods of wet and dry soil. Leaf curl symptoms are common early in the growing season when weather patterns shift from wet and rainy to hot and dry. During this transition, plants tend to experience water stress, as the rate of water leaving the leaves exceeds uptake by the roots. Plants respond by curling their leaves to reduce sun exposure, which reduces water loss. - Source: Internet
• Yes, of course! The cure for tomato leaf curl is through prevention. Ideally, you’d want to grow only pest and disease-resistant tomato varieties. And if you’re already growing these types of tomatoes but still get leaf curl, you can fix the problem by determining the cause of it and act based on that. - Source: Internet
• To prevent this problem, simply adjust your watering plant’s watering routine. You should know whether you are overwatering or underwatering your plant. If it’s not a serious complication yet due to underwatering or overwatering, the leaves of your tomatoes should return to normal. - Source: Internet
• It depends on the cause of the leaf curling. If you determine that it is due to the intense and scorching sun, then simply put a shade over your plants or if they are potted, relocate them to a shady location. If it’s due to improper watering, simply adjust your watering schedule. Essentially, you need to determine first the cause of the leaf curling before you do anything. But at the same time, you need to act fast before the problem affects your other plants. - Source: Internet
• Tomato Mosaic Virus – a.k.a. tomato leaf curl virus, this one is spread by whiteflies (particularly silverleaf whitefly) who carry the disease as well as other tomato-related plants. It causes leaf curl but also other symptoms such as unusual spotted coloring on the foliage as well as browning of the inside of the tomato fruits. - Source: Internet
• a) Leaf curl due to physiological or environmental reasons. One of the most common is dry blowing wind. Blowing winds means the rate of water loss by the plant will increase. Excessive water loss will lead to curling leaves. - 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
• 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
• 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
• The viruses produce leaf curling and yellowing at severe infection stages. Leaf curling pattern is Some leaves may curl down. Besides tomatoes, other TYLCV plant hosts include peppers and common beans. - 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. Thankfully, tomato leaf curl rarely means that your tomato plants are going to die; you can still expect a harvest this summer! - 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
• 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
• Tomatoes are particularly prone to what are known as physiological disorders: abnormal growth caused by non-infectious factors. This is partly due to the difficulty of controlling the sensitive requirements of tomatoes for temperature, nutrients and light levels. Outdoors, the plant is equally vulnerable to lack of warmth and variable temperatures. - Source: Internet
• You can treat tomato leaf curl depending on the cause. If it’s due to overwatering or underwatering, then water your tomato plant just right. And if it’s due to high temperature and too much direct sunlight, you’d want to cover your plant with some shade, and the list goes on. - 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
• In general, no, tomato leaf curl is not contagious. But if the leaf curl is due to pests or viruses, then yes, tomato leaf curl can spread. Regardless if it’s contagious or not, you should properly monitor your plant and act fast to ensure the problem doesn’t get too serious. - Source: Internet
• • Hormone weedkillers. Tomatoes are very susceptible to hormone weedkillers – even wind-born residues can have a deleterious effect on them. Be very careful to store your weed killers well away from tomato plants, especially during warm weather when even the presence of a bottle of herbicide in the greenhouse could damage your tomatoes. - Source: Internet
• Watch for leaf curl as your plants grow. Then, jump into action as soon as you spot the problem developing. Your quick response will help your plants recover faster, so you can still enjoy a big tomato harvest. - Source: Internet
• Tomatoes are very sensitive to herbicides. This means that if certain weed killers are applied nearby and some drifts onto the leaves of your tomatoes they may sustain herbicide damage. In this case the leaves will often roll downwards. - Source: Internet
• It’s rather alarming, when you check your tomatoes, to find the leaves of your prize vines curled and twisted. As long as the plant is otherwise healthy, there’s no reason to despair. By modifying the growing environment, it’s perfectly possible to undo the damage and achieve great harvests. - Source: Internet
• Leaf curl is a common problem affecting tomato plants, but often the cause is physiological rather than infectious or pest-related. Tomatoes are easy to grow but they’re more delicate than some gardeners realise. Inadequate watering, over-watering, unstable temperatures, and hormone weed killers are among the main causes of leaf curl. - Source: Internet
• You can easily fix this problem in a few approaches. You can add fresh compost around your tomatoes. Or you can use Azomite, a clay compound packed with micronutrients. And lastly, you can use an all-purpose plant feed applied around your tomato plants to amend the soil and get your tomatoes back on track. - 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
• Environmental issues are probably the most common reasons why your tomato plant leaves are curling up. This means your tomato plants are exposed to scorching temperatures or facing too much bright direct sunlight. Environmental issues can also include too much wind, which stresses your tomatoes. - Source: Internet
• Certain herbicides are applied in a tomato plantation to control weeds. If there is direct leaf contact with the spray, the plant responds in various ways. For instance, the leaves may yellow, discolor or bleach; twist, curl or roll down and wither. Petioles can exhibit drooping while stems could bend. The stem may also develop a twisted growth, crack or develop bumps with lesions. - Source: Internet
• Tomatoes might not be the most difficult plants to grow, but they’re definitely one of the trickiest. They’re prone to a variety of common problems, and often it seems like no sooner have you got them up and running than they fall apart. If you have noticed your tomato leaves curling there’s still hope! Read on for solutions to common tomato plant problems and how to fix them. - Source: Internet
• In early summer, the nights can be cold and the days very warm. This fluctuation of temperatures is the main cause of what can sometimes be a very alarming degree of leaf curling. The plant is unable to cope with the accumulation of carbohydrates that occurs if nights are too cold for plant physiological functions to occur normally. Fortunately this does not seem to be a serious cause of loss of crop and usually disappears of its own accord as the nights begin to get warmer in late summer. - Source: Internet
• The treatment for leaf curl on tomato plants depends on the cause. Too much heat? Add a shade cloth or water more often. Not enough water? Increase your watering frequency and/or amount. - 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
• Leaf veins, petioles, and parts of the leaves turn light-green or appear light-colored. Leaflets may wrinkle. Leaves often display curling down pattern. The have deformed shapes and reduced leaf sizes. - Source: Internet
• • Windy weather. Tomatoes don’t like the wind, particularly when the weather’s dry. Blustery conditions can damage the outer edges of leaves, causing them to curl. If your plants are adversely affected by the wind, consider erecting a screen – willow hurdles are a good temporary solution. - Source: Internet
• There are many consequences of tomato leaves curling. These include slow growth, weak plants, small numbers of fruits, and worse, the entire plant dying. So, diagnose your tomato plant if you see leaf curling to prevent the problem from getting bigger. - Source: Internet
• Their activity causes the leaves to curl upward. Also, tubercles may appear on the leaves where the aphids are most dense. Ants are a huge contributor to the spread of aphids. - Source: Internet
• The best strategy for preventing curled leaves in the future is to amend your soil before planting tomatoes. For soil that’s lacking in nutrients, add compost. You can either use the compost you make at home or purchase organic compost. - Source: Internet
• • Dry weather/under-watering. During hot, dry weather, tomato leaves may curl as the plants strive to conserve water. Regular irrigation can solve this problem, and for greenhouse tomatoes, judicious use of blinds or white window paint can prevent the sun scorching your tomatoes. - Source: Internet
• • Mineral deficiency. A good tomato fertiliser should mean that your plants get all the nutrients they need, but if there is a deficiency, it could manifest in the form of curled or mottled leaves. Mottling usually denotes a magnesium deficiency, but if it’s only affecting the old leaves, this isn’t a cause for concern. - Source: Internet
• The yellow leaf curl virus of the tomato is caused by begomoviruses. It is a popular tomato disease transmitted by the whiteflies species (Bemisia tabaci). The virus can also be transmitted via infected seeds. - Source: Internet
• The good news is that, as alarming as physiological leaf curl might appear to be, the disorder appears to have little detrimental effect on yield. Nonetheless, gardeners and commercial growers alike tend to become concerned when the symptoms first appear. Reducing the environmental stress that causes physiological leaf curl may help to prevent other production problems. - Source: Internet
• The most effective treatments for tomato leaf curl include correcting your watering routine, applying the right type of plant feed, and not exposing your plant to high temperature and herbicide. There are different effective treatments for tomato leaf curl depending on the cause of it. But in general, just follow all the solutions I mentioned above and you’re good to go! - 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
• Tomatoes don’t like the wind, particularly when the weather’s dry. Blustery conditions can damage the outer edges of leaves, causing them to curl. If your plants are adversely affected by the wind, consider erecting a screen – willow hurdles are a good temporary solution. - Source: Internet
• Curly top virus is the only exception. You cannot save plants affected by the virus. Instead, you need to replant your tomatoes under a row cover. Plants placed in an open garden will just get the virus again once the pests return. - 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
• 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
• Whenever tomatoes are transplanted to a new location, there’s always a risk of root damage. Keep in mind that tomato roots are quite delicate. Even a little bit of root disruption can stress the plant. - Source: Internet
• Tomatoes grown in pots are the most commonly affected by thirst. In the summertime, the soil in a pot that is placed in a sunny spot can dry out within a day. If you don’t water in the evening, the leaves can curl down the next day. - Source: Internet
• Gardeners tend to be a worrisome group, showing great concern over anything unusual about their plants. This especially is true for their tomato crop, which tends to be the pride and joy of nearly every serious gardener. It comes with little surprise, therefore, that many gardeners at this time of the year ask, with utmost concern, “Why are the leaves of my tomato plants curling?” - Source: Internet
• Plants with nutrient deficiencies may need agricultural lime or a balanced fertilizer. Leaf curling caused by excessive nitrogen requires you to hold back on the fertilizer until fruit sets, however. Curly top virus is the main exception. You cannot save plants affected by this virus. - 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
• 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
• 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
• Most gardeners are aware that tomatoes are very sensitive to herbicides. Off target drift of herbicides such as 2,4-D or dicamba, or contaminated compost containing long-lived pasture herbicides such as picloram, clopyralid, or aminopyralid are frequent offenders. Leaf curl is a frequent symptom of herbicide damage. Although symptoms vary somewhat according to herbicide, downward bending of the petioles and cupping of the leaf segments (leaflets) are quite common. Again, new growth usually is affected first. - Source: Internet
• Another cause of tomato leaves curling is the tomato mosaic virus. Because there are various strains of viruses that cause ToMV, symptoms might differ. Even though, mosaic viruses that attack tomatoes produce many similar symptoms at any stage of growth. - Source: Internet
• The best way to control tomato leaf curl is via prevention. First, you need to choose disease and pest-resistant tomato species to plant and grow. Then properly grow them by providing bright indirect sunlight, correct watering routine, correct type of fertilizer and application of it at the right time, and so on. Basically, just take care of your tomato plants well by doing research before growing them. - Source: Internet
• Herbicide damage makes the tomato leaves curl downwards and twist around the stem. New growth normally shows these signs first. Sadly, you can’t save leaves that are damaged in this way. If the damage is not that serious, new growth may develop unaffected. However, the yield of the plant will surely be impacted. - Source: Internet
• Curling tomato leaves are certainly alarming, but sometimes the cause is rather simple. Environmental stress is the most common cause of leaf curling in tomatoes, commonly referred to as rolling or physiological leaf curl. The symptoms of physiological leaf curl vary slightly from other causes. Affected leaves tend to curl upwards and inwards, with damage generally beginning on the lower, older leaves. Environmental stressors can include insufficient water, high temperatures, excessive moisture and/or nitrogen, severe pruning, or root damage. - Source: Internet
• It’s usually possible to resolve tomato leaf curl, especially if you catch the problem early. You must find the underlying cause first though. Leaves curling due to high temperatures may need a shade cloth. Alternatively, your plants might just need more water. - Source: Internet
• Tomatoes are very sensitive to herbicides. Dicamba or 2, 4-D are the typical suspects. But there are a few others that can also cause curling leaves if they come into contact with your plants. - Source: Internet
• Tomatoes are susceptible to many viruses, such as tomato yellow leaf curl virus, that cause leaves to twist and curl. Initial symptoms resemble herbicide damage, commonly affecting newer younger foliage, but viral diseases tend to progress and additional symptoms aid in identifying infection. Symptoms such as stunting, discolored foliage, leaf vein discoloration, and irregular growth commonly occur along with leaf curling. - Source: Internet
• Growing tomatoes only to see the leaves begin to curl can be very frustrating. However, understanding the problem is the first step toward correcting it. Take the time to identify the cause of your tomato curling leaves. Here are the top reasons your tomato has curling leaves. - Source: Internet
• There is a legion of insect pests of tomatoes, but the most common cause of leaf curl is aphids. They are small sucking insects that are gray or greenish in color. They are usually located at the bottom of the leaf. - Source: Internet
• Tomatoes need a lot of water for normal fruiting. But in a summer drought, there may not be enough water in the ground, causing the leaves to curl for the same purpose as in the previous case. Curled leaves evaporate less water in hot weather. - Source: Internet
• d) Break Fungal Cycle & Disease Development: First, remove lower suckers and older leaves. Second, properly space tomatoes acording to the variety you have planted. Spacing can help stop the disease from developing further. - Source: Internet
• During the summer season, when the climate starts to heat up and the sun becomes harsher, tomato plants may struggle to adapt. Tomato plants indeed love the sun. However, when the temperatures stay more than 85 degrees Fahrenheit for an extended period, tomatoes undergo heat stress. - Source: Internet
• Also, sometimes the curling of the leaves is due to cold weather or cold winds. Once the cold weather is gone, the plant will continue to grow normally. But if you want everything to be perfect, cover the tomato if the weather forecasters pass a cold snap. Or move it to a sheltered location if it’s growing in a container. - Source: Internet
• If your tomatoes are in the process of recovering from too many pruning sessions, just leave it be for now. Any unnecessary move with your plant can cause more stress while it is still vulnerable. Just let your plant rest for a while. - Source: Internet
• Physiological leaf roll or curling is not caused by a disease. Instead, it is a way in which plants respond to the changes in conditions around them. These changes are often called stress factors. - Source: Internet
• Leaf curling in tomato plants can be a worrying symptom for any gardener. This symptom can translate into a big concern for anyone doing tomato production in fields. Learn more about leaf curl patterns (up, down or rolling) in tomatoes, their causes, how to control, stop or prevent the problem where possible. - Source: Internet
• Septoria leaf spot spores are spread mainly by splashes of rainwater, insects, and equipment and through workers’ hands. The spores germinate upon landing on your tomatoes at room temperatures. Infection occurs via leaf stomata. - Source: Internet
• Overdoing your watering can have a similar effect to underwatering. You may also find your plants produce an excess of foliage but few tomatoes. Leaves might yellow and wither, or they could curl. Tomatoes like humid conditions, but they don’t like being soaked. Check for signs of oedema – lumps and nodules on leaves and stems – a sure sign you’re over-watering, and reduce as necessary. - Source: Internet
• Healthy tomato plants lead to fresh home-grown fresh summer tomatoes. So, if your tomato leaves are curling, you may be worried that you won’t get to enjoy those tasty fruits for long. But there’s good news! Curling tomato leaves doesn’t mean your plants are doomed. Leaf curling can be caused by a variety of factors, all of which can be treated and prevented. - Source: Internet
• There is no solution to this problem. The tomato will either survive or die, depending on the extent of the damage. In the future, be extra vigilant when working with herbicides near tomatoes and other plants. - Source: Internet
• Obviously, yes! Tomato leaves curling can sometimes have yellowing (a.k.a. tomato yellow leaf curl), but tomato leaves that turn yellow don’t necessarily curl. Their causes are almost the same, mainly environmental reasons such as too much sunlight, overwatering, underwatering, excessive fertilizer, pests like mites, and so on. - 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
• 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
• • Too cold. Tomatoes don’t like it when temperatures dip below 12C. If that’s the case, the plants can’t process the carbohydrates they’ve produced during the day, and the leaves may curl. While temperature variation is often a problem during the warm days and chilly evenings we experience during the spring, conditions improve as we move into the summer. If the weather is extreme, you could cover your plants with fleece during the night time, but otherwise, this is a problem which normally resolves without permanently affecting leaves or harvests. - Source: Internet
