Wilting tomato plants — BBC Gardeners' World Magazine


Tomato plants are a popular choice for home gardeners due to their delicious fruits and relatively easy cultivation. However, sometimes these plants can start to wilt, which can be concerning for any gardener. Wilting tomato plants can be caused by a variety of factors, including environmental conditions, diseases, and pests. In this article, we will explore the common causes of wilting tomato plants and provide solutions to help revive your beloved plants.

1. Lack of Water

One of the most common reasons for wilting tomato plants is a lack of water. Tomatoes require consistent moisture to thrive, especially during hot summer months. If the soil is dry and the leaves are droopy, it’s a clear sign that your plants need watering. Water deeply and ensure the soil is evenly moist, but not waterlogged.

2. Overwatering

On the flip side, overwatering can also cause wilting in tomato plants. When the roots are constantly saturated, they can’t absorb oxygen properly, leading to root rot and wilting. Make sure to water your plants only when the top inch of soil feels dry. Water deeply but allow the soil to dry out slightly between watering sessions.

3. Extreme Temperatures

Tomato plants are sensitive to extreme temperatures, both hot and cold. High temperatures can cause the plants to wilt, especially if they are not receiving enough water. Similarly, sudden cold snaps can shock the plants, causing wilting. Provide shade during scorching days and protect your plants from cold weather to prevent wilting.

4. Nutrient Deficiencies

Wilting tomato plants can also be a sign of nutrient deficiencies. Tomatoes require a balanced supply of essential nutrients, including nitrogen, phosphorus, and potassium. Insufficient levels of these nutrients can hinder plant growth and lead to wilting. Consider using organic fertilizers or compost to provide your plants with the necessary nutrients.

5. Diseases

Various diseases can affect tomato plants and cause wilting. One common disease is bacterial wilt, which is caused by the bacterium Ralstonia solanacearum. This disease clogs the plant’s vascular system, preventing water and nutrients from reaching the leaves, resulting in wilting. Remove and destroy infected plants to prevent the spread of the disease.

6. Pests

Pests, such as aphids and spider mites, can also cause wilting in tomato plants. These tiny creatures feed on the sap of the plants, causing dehydration and wilting. Regularly inspect your plants for any signs of pests and use appropriate organic insecticides to control their population.

7. Improper Pruning

Pruning is an essential practice for tomato plants, promoting better air circulation and preventing diseases. However, improper pruning can damage the plants and lead to wilting. Make sure to prune only the necessary branches and avoid excessive pruning, especially during hot weather.

8. Transplant Shock

When transplanting tomato seedlings into the garden, they can experience transplant shock, resulting in wilting. The plants need time to adjust to their new environment and establish their root systems. To minimize transplant shock, water the seedlings thoroughly before transplanting and provide some shade or protection during the first few days.

9. Overcrowding

Lastly, overcrowding can lead to wilting in tomato plants. When the plants are too close together, they compete for resources, including sunlight and nutrients. This can cause stress and wilting. Ensure proper spacing between plants to allow for adequate airflow and growth.


Tomato plants can wilt due to various reasons, including lack of water, overwatering, extreme temperatures, nutrient deficiencies, diseases, pests, improper pruning, transplant shock, and overcrowding. By understanding these common causes and implementing the appropriate solutions, you can revive your wilting tomato plants and ensure a healthy and productive harvest.
