Tomato Leaves Curling Up. If the leaves of your tomato plants bend or curl, the problem may be due to biological, chemical, or physical factors. Sometimes all the leaves curl, sometimes only the young leaves curl. In today’s article, we are going to look at the 5 reasons why leaves curl up on a tomato plant and how to fix it.
Tomato Leaves Curl Up on Tomato Plant Due to Environmental Damage
Tomato Leaves Curl Up on Tomato Plant Due to Environmental Damage. This is one of the main causes of tomato leaves curling up on tomato plants and also one of the most common and easy to treat.
Strong wind and low humidity can damage the leaves of tomato plants. Heat causes them to dry out and subsequently fold and curl.
Hot and dry weather can cause physiological curling which is the plant’s self-defense to prevent further water loss. This physiopathology does not decrease crop yields if it is isolated unless it is severe, in which case it would affect production. Plant health will improve when climatic conditions improve.
Tomato Leaves Curling Up Due To Herbicide Drift Damage
Tomato Leaves Curling Up Due To Herbicide Drift Damage. Many of you do not apply herbicides to your crops because this is a website where everything we use is organic, but herbicide drift can occur. And what is drift? Well, a neighbor or crops next to yours use chemicals to treat weeds or pests and the wind moves them to your garden damaging the tomato and causing tomato leaves to curl up on the tomato plant.
A light wind of 3 mph (5 km/h) can be enough to move the herbicide up to 0.6 mi (1 km) away, causing enormous potential damage.
To know if you have been affected by this, we must observe the plant if it corrects or not the rolled leaves because if they dry and die it may have been caused by the drift.
Tomato Leaves Curling Up on Tomato Plant Due to Herbicide Residues in Mulch and Manure
Tomato Leaves Curling Up on Tomato Plant Due to Herbicide Residues in Mulch and Manure. Even when buying mulch such as straw or hay, we should find out if it has been treated with herbicides during its cultivation, since they remain in the plants for up to 18 months and can cause damage to the vegetables in the garden.
The seller should inform us if the crops have been treated with aminopyralid and if he does not inform us, we should ask. Moreover, the herbicide may even remain in the compost because the animals have ingested the contaminated fertilizer.
A solution to eliminate this herbicide can be to spread the plants or the compost on the ground so that the sun shines on it and to water it so that the process is faster.
