Cabbage is a plant that requires special care from a person. Quite often, she is exposed to various diseases. The most common are black leg, late blight, powdery mildew, gray and white rot. Also, gardeners often face the problem of leaf curling. To get rid of this problem, you need to figure out why cabbage leaves curl.


Most often, this problem occurs with young seedlings. There are several main reasons why cabbage leaves curl:

  • Lack of nutrients;
  • Some gardeners do not properly prepare the soil for seedlings and because of this, the plant lacks nutrients.

Lack of phosphorus often leads to twisting. This phenomenon can appear immediately after the cabbage is planted in a permanent growing area. Also, the leaves are curly due to a lack of potassium. You can get rid of this with wood ash. It must be placed under the base of the cabbage.

Lack of micronutrients

The sheets can curl due to a lack or excess of zinc, sulfur, copper and boron.

With a lack of boron, the leaves on the cabbage begin to curl and brighten. In some cases, they turn purple-red.

The youngest sheets are the first to feel the lack of copper. They immediately begin to curl up. If you do not timely add preparations that contain copper to the soil, then the cabbage will begin to turn yellow and dry out. It is best to use mixtures containing sulfur with copper, as they increase each other's effectiveness.

A large amount of zinc affects old leaves. They curl and become more fragile. With a lack of calcium, they not only spin, but also turn very white.

Excess mineral fertilizers

During overfeeding with nitrogen-containing fertilizers, the leaves begin to curl into a ring. At the same time, their plate becomes very dark and brittle. Due to the large amount of nitrogen, the intake of phosphorus is blocked. To correct this problem, you need to use phosphorus-potassium fertilizers, which should be applied to the soil during irrigation.


At an air temperature of more than +30 ° C, the leaves begin to curl inward. When it gets a little cooler outside or indoors, they return to their normal shape. In order for the plant to better tolerate high temperatures, it is necessary to spray it with micronutrient fertilizers or a solution of potassium permanganate.

Lack or excess of moisture

Lack of moisture is observed at high temperatures and low air humidity.

Because of this, the leaf falls down and curls into a tube. With an excess of moisture, they become very brittle and rise upward.

Aphid attack

Some people don't immediately understand why cabbage leaves curl. Quite often this happens due to aphids. This insect causes enormous damage to the plant. It sucks out all the cabbage juice from it, which is why the leaves begin to become covered with white spots. Over time, the growth of cabbage slows down and it dies. Therefore, it is necessary to fight aphids immediately after their appearance.

Whitefly attack

This white midge, which looks a lot like a small moth, often attacks cabbage. It lays its larvae on the leaves, which feed on the sap of the plant.

After a while, because of this, the leaves of the cabbage curl. If you do not get rid of the whitefly in time, then the cabbage will dry out.


Many novice gardeners do not know what to do if the leaves are curling. To return them to their previous shape, it is necessary to properly care for the plant during cultivation.


You need to know how to properly water the cabbage so that the leaves do not curl due to a lack or excess of moisture. Watering is recommended only in the evening 1-2 times a week. In summer, cabbage is watered every two days. To preserve moisture on the surface of the soil, a mulching peat layer of 5-7 cm is made.

Top dressing

Proper feeding will help maintain the optimal amount of nutrients and trace elements in the soil. You need to feed the plant 15-20 days after planting. During the growth of cabbage, the procedure is carried out three times:

  • First feeding. To create a mixture, 2 g of nitrate, 5 g of superphosphate and 2 g of potassium fertilizer are mixed with a liter of water. This is enough to fertilize 30-50 bushes.
  • Second feeding. It is carried out one week after the first. During the creation of the solution, a liter of mullein and poultry droppings are mixed with 10 liters of water. No more than one liter of the mixture is consumed per bush.
  • Third feeding. Held in early June or late May. During the preparation of the solution, a tablespoon of potassium sulfate and superphosphate is mixed with 10 liters of water. A square meter of the site should be treated with 3-5 liters of the mixture.


It is possible to protect cabbage from diseases and pests that cause the leaves to roll up with the help of proper processing. Immediately after planting the plant, tobacco dust with ash must be added to the ground. This will protect her from fleas and slugs.

We fight aphids with a solution from tomato tops: add 3 kg of tops to a five-liter pot of water. The mixture is boiled and infused for about three hours. After that, it is filtered and diluted with cold water.

You can also spray the plant with onion peel solution. To prepare it, boiled water is added to a liter jar with husks and insisted for several days. After that, another three liters of water are added to the mixture.

You can fight harmful insects with the help of spicy plants: sage, mint, rosemary, cilantro. They need to be planted near the cabbage.


Leaf curl in cabbage is a fairly common problem and is not that difficult to get rid of. To do this, it is enough to properly care for the plant and know how to process it.
