Why do strawberries turn yellow?

v

Most gardeners plant strawberries in their summer cottages. At the same time, this fruit plant often suffers from various diseases and parasites. Today we will talk about why strawberries turn yellow and what to do about it.

The reasons

Strawberries can turn yellow for a variety of reasons. Let's consider the main ones.

Sun exposure

Ultraviolet rays can severely burn strawberry leaves. This will cause them to turn yellow. After a while, the leaf blades dry out completely, and the plant dies.

Most often, young, not yet strong fruit bushes suffer from an excess amount of sunlight. So that the seedlings do not suffer from this, they should be planted in a place where during the day they can stay both in the shade and in the sun. Also, in too hot weather, you can build special shelters for strawberry or strawberry bushes from other plants or a special garden film. They will allow you to create a shaded place above the plants.

In addition, in such weather, the abundance of watering and its frequency should be increased. After all, the earth will dry out too quickly, which will have a bad effect on the plant.

Acute mineral deficiency

Often strawberries turn yellow due to an acute lack of magnesium. Most often, plants lack this particular element. To cure Victoria in this case, you need to make special dressings.

Sometimes seedlings do not have enough nitrogen.As a rule, such a problem occurs in early spring, because it is difficult for the root system to get this element from the still poorly warmed earth. With a lack of nitrogen compounds, the leaf blades begin to turn slightly yellow. But in the final stages, they acquire a bright lemon color. In such a situation, ammonium nitrate must be added.

Boron deficiency can also cause Victoria to turn yellow. In addition, berries and flowers grow much less. In this case, it is necessary to make top dressing with boric acid.

Often strawberries are damaged due to a lack of iron. This leads to the fact that young leaves between the veins begin to turn yellow. Then you should immediately treat the plants with chemicals. The most effective remedy is a solution of copper sulfate (two tablespoons of copper sulfate per 10 liters of water).

lack of moisture

If Victoria bushes do not receive enough moisture, then they will not be able to properly absorb all the necessary nutrients. But at the same time, it is impossible to water the strawberry beds too often, because this can lead to fungal diseases. Strawberries are recommended to be watered only in the early morning, so that the moist earth can dry out a little before the temperature drops in the evening.

When watering, up to 10-13 liters per square meter of land should be consumed.

In summer, in hot weather, you can slightly increase the amount of watering.

Diseases

Most often, the leaves on strawberries turn yellow due to xanthosis (strawberry jaundice). And at first they begin to change their natural color only at the edges. But then the leaf plates are completely painted yellow.

At the final stages, the leaves become smaller, strongly deformed, and the petioles are significantly shortened.There are too few fruits. They lose their taste.

This disease spreads along with planting material. Aphids are the main carrier of xanthosis. It is almost impossible to cure this disease.

In addition, strawberry leaves may turn yellow in the initial stages of gray rot, verticillium wilt, late blight, and powdery mildew.

From these diseases, seedlings can be cured with effective, fast-acting chemical agents.

Pest activity

Often, Victoria leaves turn yellow due to the appearance of weevil, spider mites, May beetle or aphids. Most gardeners claim that only effective chemicals can help in the fight against such parasites. Moreover, the first treatment with the agent should be carried out even during flowering.

What to do?

If you notice yellow spots on your strawberries, then you should carry out several procedures.

  • First, apply special dressings. As them, compositions with iodine, potassium permanganate or whey are most often used.
  • It is also recommended to apply fertilizers with humus to the soil around strawberries. In early spring, it is better to use only nitrogen compounds. But remember that you should be careful with this element. After all, its excess can lead to an excessive increase in the green mass of plants.
  • Dolomite flour will also be useful. It is most commonly used for magnesium deficiency. Many gardeners advise periodically treating plants with soapy water, infusion of bitter red pepper, and decoction with chopped garlic.
  • If you find pests on strawberry bushes, then it is better to immediately treat them with chemicals. The most effective of them are Fitoverm, Iskra.Often, gardeners alternate the use of folk and chemical methods.
  • If the strawberry was affected by a strong virus, then all the bushes are removed from the site. They must be burned immediately so that they cannot infect other crops.

Prevention

To prevent yellow spots on victoria leaves, it is necessary to carry out some preventive procedures in a timely manner.

  • So, do not forget about watering, because Victoria has poorly developed roots, so a moisture deficit will immediately be felt. Poor watering can lead not only to the fact that the leaves begin to turn yellow, but also to the fact that the strawberry will become too weak and will soon begin to wither.
  • Do not forget to regularly cultivate the land to destroy all the harmful bacteria that have settled in it. To do this, heat treatment with boiling water should be carried out. They will kill many parasites.

Recommendations

      • Before planting strawberry seedlings, each gardener needs to choose the most suitable place for this. Remember that you should not plant this plant in areas where tomatoes, peppers, eggplants or potatoes were previously grown. Old pests left after these crops can subsequently damage Victoria.
      • Also, do not forget, the older the plant, the more diseases and parasites it has. Therefore, it is recommended to make periodic transplants. This procedure should be carried out every two years.
      • Remember to remove all weeds around the strawberries in a timely manner. And they can not be used for compost. It is better to put such harmful plants in a separate place. After all, they can become a favorable zone for the development of harmful bacteria and parasites.
      • You need to grow only pure varieties and absolutely healthy strawberry seedlings in your summer cottages.If the planting material was initially infected and had pests, then you should not wait for a full-fledged harvest.
      • If you want to breed several different varieties of strawberries in your summer cottage at once, then they should be planted at a certain distance from each other so that they do not pollinate, and they have no opportunity to intertwine with their whiskers.
      • Many experienced gardeners advise on the ground for future strawberry bushes to first plant garlic or mustard. These crops repel most of the pests that are dangerous to Victoria.
