Tomato plants are known for their delicious fruit and healthy benefits. They require proper care and attention to bear quality fruits. However, sometimes tomato plant leaves start curling up, which can be a sign of stress or damage. If you're experiencing this issue with your tomato plants, read on to understand what causes it and how to fix it.

Causes of tomato plant leaves curling up

There are several reasons why tomato plant leaves start curling up. We've listed a few below:

1. Environmental stress

Tomatoes are sensitive plants that can be affected by various environmental factors. For instance, high temperatures or intense sunlight direct on the plant can cause stress to the roots and trigger leaf curling. Similarly, lack of water, excess water, or insufficient nutrients can result in leaf curling.

2. Pests and diseases

Pests and diseases are another leading cause of leaf curling in tomato plants. Common culprits include spider mites, aphids, thrips, whiteflies, and fungi. These pests can suck out the sap from the leaves or transmit viruses, which lead to curling leaves.

3. Herbicides

If you recently applied herbicides near your tomato plants, they might be the cause of the curling leaves. Some herbicides can cause the leaves to curl as a result of exposure.

How to fix tomato plant leaves curling up

Now that you know some of the reasons why your tomato plant leaves are curling up, let's dive into how to fix the issue:

1. Environment

Provide the tomato plants with enough water and nutrients to keep them healthy. Avoid exposing the plants to extreme temperatures and keep them in shaded areas if possible. Mulching around the tomato plant can also help retain moisture and regulate soil temperature.

2. Pests and diseases

Regularly inspect your tomato plants for pests and diseases, and use appropriate control measures to manage them. You can use natural predators, insecticides, or fungicides depending on the pest or disease type. Ensure you follow the recommended application rate and timing to avoid any harm to the plant.

3. Herbicides

If herbicides are the culprit, discontinue using the product and follow up with postemergence care. You can remove the affected leaves or trim affected branches to foster new growth. If the herbicide exposure is severe, consider transplanting the tomato plants elsewhere.
