Inadequate Watering and Nutrients

Tomatoes are heavy feeders and require proper watering to ensure they receive essential nutrients. If your tomato plants are not receiving enough water and nutrients, the leaves may curl as a defense mechanism, to reduce water loss by minimizing their surface area.

To avoid inadequate watering and nutrients, ensure that you water your tomato plants deeply and evenly once a week, and use a high-quality fertilizer that is rich in nitrogen, phosphorus, and potassium. You may also consider using compost or organic matter to improve soil quality and nutrient content.

Temperature Fluctuation

Another common reason why tomato plant leaves curl is temperature fluctuation. Tomatoes are warm-season plants that perform best between 60 to 90°F. If temperatures rise above or drop below this range, the leaves may curl inward as a way of protecting themselves from heat or cold stress.

To avoid temperature fluctuation, plant your tomatoes in an area that receives plenty of sunlight but is sheltered from intense heat or cold winds. You may also use row covers or parasols to regulate temperature and protect your plants from severe weather conditions.

Pests and Diseases

In addition to inadequate watering, nutrients, and temperature fluctuation, pests and diseases are another common reason why tomato plant leaves curl. There are several pests and diseases that attack tomato plants, including aphids, spider mites, whiteflies, and blight.

To prevent and treat pest and disease infestations, ensure that you inspect your tomato plants regularly and keep them clean and healthy. You may also use natural or organic pesticides and fungicides, or consult with a professional gardener or extension agent to identify and address any pest and disease issues.
