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 plant 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 you water tomatoes 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.
How does Epsom salt help tomato plants?
Early in the season, apply Epsom salt to the soil to help germination, early root and cell development, photosynthesis, plant growth, and to avoid blossom-end rot. Later in the season, use an Epsom salt spray to improve tomato and pepper output and keep plants green and bushy.
Will tomato leaves uncurl?
As soon as the earth begins to dry up a little bit, the leaves should begin to uncurl within a few days.
What curling leaves mean?
When the tips and edges of the leaves curl inward, also known as “cupping,” this indicates that the plant is attempting to conserve moisture. The presence of downward curling in any form is almost always an indication of overwatering or overfeeding.
