What Causes Leaf Curl On Tomato Plants?
Tomato leaves curl mainly due to malnutrition, which maybe brought about by lack of fertiliser, poor watering and planting in poor soil. Exposure to more than the required eight hours of sunlight will dry the leaves up causing them to roll. Infestation by such insects as spider mites and aphids will drain the leaves of nutrients causing them to curl and die.
