Rolled leaves on plants: why and what to do

When it comes to growing plants, the most important thing is always to learn to recognize the state of these. Since plants use very different forms of communication than animals, recognizing their signals is a laborious job of patience and trial and, unfortunately, error. One of the symptoms that something is not right with your plants is that you find twisted leaves or coiled on their stems. Sometimes it is only a few leaves, in others it affects a large part of them. In any case, it is always a sign that something is wrong and that your plant needs attention before the damage is greater.

If you want to know why plant leaves curl and how to prevent or treat the problem, join us in this EcologíaVerde article about why there are curled leaves on plants and what to do.

physiological stress

This is one of the four main causes that causes the leaf curl in plants and also one of the most common and easy to treat.

Plants, like all living beings, are susceptible to climatic conditions, such as wind, extreme temperatures or dehydration, only that, as they do not have locomotion capacity, they are even more exposed to the elements. All of these things can wear down the plant, which rolls and folds its leaves as a form of defense before a very dry or hot environment: by offering less surface susceptible to sunlight, they also minimize water loss through evaporation. Grasses are particularly prone to this method of survival, the state of their leaves being a clear indicator of the plant’s level of hydration.

To deal with this problem, you simply have to protect the plant from the element that is stressing it or, if it is something specific and not very serious, simply wait for it to pass: the plant will recover as soon as its conditions improve again. Thus, it will suffice to protect it from the too intense sun, increase the frequency of irrigation or protect it from the wind. For example, here you can learn more about when to water the plants.

herbicides

If you use herbicides in your crop or garden, which we never recommend in favor of organic and sustainable farming, your plants can be damaged by these products, causing the well-known monkey hands or lace threadswhich particularly affect the tomato plants.

In fact, you don’t have to be the one who applied the herbicide products, because the drift, that is, the wind or the elements, can drag the products to your orchard or garden if a neighbor has used them. A light wind of 5 km/h can be enough to carry the herbicide up to 1 km away, potentially causing enormous damage.

If your plant has bent leaves from herbicide damageUnfortunately there is very little you can do. Make sure that the soil you plant in does not have residual deposits of any of these products and do what you can to ensure that people close to you avoid these very destructive chemicals. It is also important, if you buy padding or manure, to check that it does not contain residues of these substances, which can remain in the product for up to 18 months.

pests

There are many insect and mite pests that attack plants by feeding on their sap, especially in the leaves, where it is easier to obtain it. One of the most common pests that causes wrinkled and rolled leaves is the white mite, particularly voracious with Solanaceae. This small mite bites the leaves to suck the sap out of them, causing them to curl up from the toxins they transmit.

The white mite hides on the underside of the leaves and, although it is difficult to see, its small oval eggs can be identified. doWhat to do if plant leaves curl because of this mite? Once located, it is easy to treat with sulfur or any ecological acaricide.

Virus

There are also many viruses that can cause this symptom in our plants, hundreds of them, in fact. stand out the geminiviruseswhich thrive especially among tomatoes and some other plants, to which they always arrive propagated by the white fly. The affected plant is unable to provide sufficient nutrients to the leaves of the bud, which turn yellow and remain shrunken and curved. On the other hand, in the potato or potato it is also usual the PLRVwhich can take a long time to show clearly and ends up causing the plant to curl up and become dwarfed, with some leaves turning purple or blackening at the margins.

Unfortunately, most of the time there is no treatment, so the only solution is to uproot the plant, being very careful not to transmit the virus to any other, put it in a well-sealed bag and dispose of it safely.

Here we tell you how to eliminate and prevent the whitefly to avoid the problems it causes directly and indirectly, such as these viruses.
