The other part showed no curl at all. This part was removed because it was too close to the ground. The plant will recover if the other parts are removed, but it will not recover as quickly as the first part.

What are the signs of over watering tomato plants?
Overwatered plants may have wilted or yellowed stems and leaves, or the leaves might develop bumps and blisters or fall off entirely if plants continue to get too much water. Once the case is severe enough, it is a good idea to look at the soil around the plant.
If you notice that your plant is wilting, you may need to water it more often than usual. This is especially true if you have a large number of plants in a small pot. It’s also a good idea to check your plants regularly to make sure that they’re getting enough water and nutrients.
Can overwatering cause tomato leaves to curl?
As overwatered tomato plants mature and begin to set fruit, the topmost leaves curl inward and upward. The leaves are either firm or brittle. The symptoms are not indicative of the sudden death of the plant. Instead, it’s a sign that the plants are in good health and are ready to harvest.
How do you treat leaf curls?
It is possible to control leaf curl with a spray of a registered fungicide at any time of the year. When the buds are swelling, spraying is the most effective way of controlling them. The fungus can’t be controlled once it’s entered the bud. Fungicides are available from many sources.
The most common are pyrethroid insecticides, such as pyrethroids, which have been used for many years for control of fungal diseases. Pyrethrins are also effective against many other insects, including mites, aphids and thrips. They can also be used in combination with other fungicides to produce a broad-spectrum insecticide that can be applied to a wide range of plant species.
However, they are not suitable for use on trees, shrubs and vines, as they can cause damage to the roots of these plants. In addition, the high toxicity of some of their active ingredients makes them unsuitable for the use of many people, especially those with weak immune systems. For this reason, many growers prefer to use a combination of insecticidal and fungicidal sprays to achieve the best results.
What causes leaf curl?
One of the most common disease problems in peach orchards is peach leaf curl, which affects the blossoms, fruit, leaves, and shoots of peaches. Peach leaves curl in the spring and early summer when the temperature is warm and the humidity is high. The disease is most severe in warm, dry climates, but it can occur in hot, humid climates as well.
It can also occur on peach trees that have been damaged by other diseases, such as peach blossom spot, peach blight, or peach leaf spot. Symptoms of peach curl vary depending on the type of tree and how it has been treated with fungicides and insecticides.
If you suspect that your peach tree is infected, contact your county Extension office or your local peach grower for more information on how to control the disease. Peach curl can be controlled by applying a fungicide or insecticide to the affected area.
What does it mean when leaves curl up?
Heat stress causes rapid evaporation, so plants curl up to conserve moisture. If you must water, do so only when the soil is dry and the plants are dormant.
Should I cut off curled tomato leaves?
When tomato leaf curling is due to a viral infection, the disease can be controlled by the use of an anti-viral agent. In this study, we investigated the effect of a single oral dose of the anti-viral drug, acyclovir (ACV), on the growth and yield of tomato plants grown in the field.
The results showed that ACV treatment significantly reduced the number of infected tomato leaves (P < 0.05) and the length of time the leaves remained infected (Fig. 1A). The treatment also significantly decreased the amount of virus-infected leaf tissue, as indicated by a significant decrease in total leaf viral load (Table 1).

What do Overwatered tomato leaves look like?
A tomato plant that is overwatered will look dull and depressed. On top of this, it might have yellowing leaves that’ll eventually turn brown around the edges. The fruit of a tomato that has been overwatered will be smaller than normal. If you notice that your tomatoes are wilting, you can check the soil around your plants to see if it’s getting wetter. If it is, then you should consider replanting the plants.
What does an Underwatered tomato plant look like?
Tomato plants that are temporarily water-stressed will have wilted leaves that are still green. Tomato plants that are regularly or chronically water stressed conserve water in their roots and stems while allowing leaves to yellow, usually starting with the lower leaves.
Watering tomato plants with fertilizers will not increase the amount of nitrogen in the soil, but it will improve the quality of the plant’s root system. If you fertilize your tomato plant with a high-nitrogen fertilizer, you may need to water it more often.
What are the symptoms of leaf curl?
Symptoms of leaf curl appear in the spring. Developing leaves become severely distorted (thickened and puckered), and have a reddish or purple cast. The leaves become gray in color as the spores form on the surface. The leaves turn brown or yellow after this.
