When the temperature is high and there is not enough moisture in the air, the margins of the tomato leaves might die back and then twist and curl. The symptom known as physiological leaf roll can also be brought on by hot and dry conditions. This is a self-defense mechanism that causes the leaves and leaflets to curl ever-so-slightly to prevent the plant from losing any more water (Fig.6).
Why are the leaves on my tomato plants curling up?
The leaves on your tomato plant may curl up occasionally; this is quite normal and won’t in any way harm the plant. The inward curling of leaves of this sort is usually always a reaction to some kind of environmental stress. The leaves of your plant will curl up to defend themselves if it is being subjected to an excessive amount of sun, extremely high temperatures, an excessive amount of wind, or a lack of water.
Should tomato plants be watered every day?
It is important to provide adequate water to newly planted tomatoes in order to maintain a wet soil environment that is conducive to plant growth. It is best to water plants first thing in the morning at the beginning of the growth season. It is possible that you may need to water tomato plants twice each day when the temperatures rise.
Does tomato leaf curl go away?
In most cases, if you refrain from overwatering or work to improve drainage, this issue will resolve itself on its own. One thing you may do to reduce the risk of heat and sun damage to your tomatoes is to cover them with a shade cloth and maintain a constant watering schedule, being careful not to saturate the soil with water.
How do you treat curly leaves naturally?
Spraying sulfur or copper on the plant after the leaves have fallen in the autumn and then again in the spring is the most popular approach used to address leaf curl. It is generally accepted that once the leaves have been infected, there is little that can be done to remedy the situation while the season is still active. And so you will have to hold off until the fall.
