Do you love the taste of fresh tomatoes in the summertime but can’t seem to keep your tomato plants from wilting? You’re not alone! Wilting tomato plants are an all too common problem for gardeners, but luckily, there are some helpful solutions. This article will look at the causes and solutions for wilting tomato plants so you can revive your crops and enjoy your delicious tomatoes. Let’s dig in!

Causes of Wilting Tomato Plants

Several factors can cause wilting tomato plants, and it’s essential to identify the causes to take the appropriate corrective action. Typically, wilting tomato plants can be attributed to a lack of water, nutrient deficiency, pest or disease, or extreme temperatures. Inconsistent irrigation practices can cause a lack of water, or the soil may contain too much clay or other substances that can impede water absorption. Nutrient deficiency can be caused by inadequate soil fertility or pH, while pests and diseases can cause the plant to become weak and eventually wilt. Extreme temperatures can occur when the temperature rises too high, resulting in the plant not receiving enough water and nutrients to survive.

Lack of Water

One of the most common causes of tomato plant wilting is lack of water. Tomato plants require at least one inch of water per week, and more during dry periods, to remain healthy and thriving. If your tomato plants are wilting, check for signs of dehydration, such as brown and dry leaves, before doing anything else. Water your tomato plants deeply and regularly, and if possible, invest in a soaker hose to ensure your tomatoes are getting enough water to keep them from wilting.

Insufficient Sunlight

One common cause of wilting in tomato plants is insufficient sunlight. When a tomato plant is not getting enough sun, it may start to wilt and eventually die. To combat this, ensure your tomato plants get at least six hours of sunlight daily. If you live in a place with short days, you may need to supplement your tomato plants with artificial lighting. Additionally, be sure to rotate your tomato plants regularly so that all sides of the plant get the same amount of light. Finally, trim your plants regularly to allow for better air circulation and sunlight penetration. By following these steps, you can ensure your tomato plants have the light they need to thrive.

Disease or Pests

Tomato plants can suffer from disease or pest infestations that may cause leaves to wilt. A common culprit is the tomato hornworm, a large, green caterpillar with a distinctive horn-like tail. It can quickly devour a tomato plant, and its larvae can wipe out an entire garden. To prevent wilting from hornworm infestation, regularly inspect your plants for signs of damage, and take action to get rid of the hornworms as soon as possible. Other causes of wilting may include bacterial and fungal infections and nutrient deficiencies. To reduce the risk of wilting, ensure that your tomato plants have the right amount of sunlight, water, and nutrients, and regularly inspect them for signs of disease or pests. These steps can help ensure that your tomato plants are healthy and vigorous.

Poor Soil Quality

One of the leading causes of wilting tomato plants is poor soil quality. If your soil doesn’t have enough nutrients, it will be hard for your plants to get the nutrients and water they need to thrive. Tomato plants need lots of nitrogen, phosphorus, and potassium to grow healthy and strong. You can test your soil’s nutrient levels to determine if it needs any amendments. Additionally, soil that is too dense or too acidic can cause tomato plants to wilt. You can use soil amendments like compost, lime, and gypsum to help improve your soil’s texture and nutrient levels.

Solutions for Wilting Tomato Plants

Fortunately, there are several solutions to help revive your wilting tomato plants. One of the most straightforward solutions is to provide adequate water. Before watering your tomato plants, ensure they are planted in well-draining soil. If the soil has poor drainage or your tomato plants are in a container, water them more often. Increase the frequency of watering if your soil is particularly dry. Additionally, mulching can help retain moisture in the soil and reduce water loss.

To support healthy growth, you should also fertilize your plants regularly, following the instructions on the package for the best results. If you notice your tomato plant is wilting despite being adequately watered, the plant may have a nutrient deficiency. In this case, you should consider purchasing a fertilizer designed for tomatoes. Finally, ensure your tomato plants are not exposed to excessive sunlight, which can cause wilting. Provide enough shade to protect your plants from extreme heat.

Increase Watering Schedule

One of the most common causes of wilting tomato plants is a lack of water. To combat this, you should increase your watering schedule and make sure your plants receive enough hydration. When watering, check the soil and not just water the leaves. Also, ensure to water the base of the plant, not just the top of the soil. Finally, keep an eye on the weather. Your tomato plants might need a little extra water if it’s hot and dry.

Provide Adequate Sunlight

If you’re trying to keep a healthy tomato plant, one of the most important things to keep in mind is ensuring it’s getting enough sunlight. Depending on the variety of tomato plants, it usually requires 6-8 hours of sunlight per day, so be sure to put your plants in a sunny spot in your garden. If your tomato plants are showing signs of wilting, they might not be getting enough sunlight, or it could be a sign of over-watering. If your tomato plant is wilting, try increasing the exposure to sunlight and see if that helps.

Identify and Treat Pest or Disease Problems

If your tomato plant is wilting, it may be caused by a pest or disease. It often helps to inspect the plant and look for signs of pests or diseases. If you notice any signs of pest or disease, it is essential to treat the issue as soon as possible. Common pests and diseases that may cause tomato plants to wilt include tomato hornworms, aphids, blight, and root-knot nematodes. Depending on the type of pest or disease, the treatment may involve applying pesticides, fungicides, or plant-based remedies. It’s also essential to ensure your tomato plant gets the proper water and nutrients to help it remain healthy and not succumb to pests or diseases.

Improve Soil Quality

Improving soil quality is essential for your tomato plants to thrive. Improving your soil’s composition will help it hold onto moisture, allowing plants to take in the nutrients they need. The ideal soil composition should be roughly equal parts organic matter, sand, loam, and clay. You can add compost, mulch, and other organic materials to your soil. The soil should also be tested to ensure it has the optimal pH levels and nutrient availability to encourage your tomato plants to flourish. Poor soil quality can cause tomato plants to wilt, so pay attention to this critical factor when caring for your plants.


Wilting tomato plants can be a cause for concern, especially for those that rely on their crop for income or sustenance. As we have seen, many factors can cause wilting tomato plants, ranging from inadequate watering and insufficient sunlight to pests and diseases. Fortunately, various solutions can be implemented to help prevent wilting tomato plants and promote better health and growth. You can prevent wilting and enjoy a fruitful harvest by taking the time to care for your plants properly.
