Usually, strawberry leaves turn red when autumn begins. In August or September, they turn purple and dry out. This speaks of a natural process. However, if this happened as soon as spring began, or in the summer months, it is worth sounding the alarm. The fact is that a leaf is an indicator of the state of culture. The appearance of the foliage and its color determines the health of the plant. It is important for a gardener to know why the leaves of strawberries turn red, what to do with this process, how to treat the berry, and how else can the foliage change color.

Strawberry treatment rules

Garden strawberries (this is the official name for strawberries) need constant care. A special place in agricultural technology is occupied by the treatment of diseases and the control of pests of the berry bush. Only a culture that is given time has excellent fruiting.

General rules for the treatment of diseases and pest control consist of the following points:

  • As soon as the snow melts and the soil begins to warm up, the gardener waters the garden with water at a temperature of at least 55 degrees. Boiling water helps to get rid of pests and bacteria. It is recommended to prepare a hot manganese solution. So the soil will be better disinfected. Processing with a hot solution of copper sulfate is allowed. The agent in the amount of 10 grams is dissolved in a 10-liter bucket of boiling water. You can do without boiling water. Then the strawberry bed is watered with Bordeaux liquid (3%).

Red leaves on strawberries

  • Dried or damaged leaves are removed throughout the season.
  • Aromatic plants are planted next to the strawberries. Among the popular ones: marigolds, calendula. They will scare away pests.
  • Diseases are treated with different drugs. For example, wilting can be defeated with the biological product Trichoderma verde. Fruit rot will go away if you transplant strawberries away from the area with raspberries, spray before flowering with either ash infusion, or mustard infusion with garlic, or biological fungicide Alirin B.
  • With an invasion of a transparent mite, the culture is treated with high temperatures. Cover the entire strawberry patch on a very hot day with plastic wrap. A thermometer is placed there. As soon as it reaches +60 degrees, the film can be removed. Next, each bush is cut off, leaving only a small petiole. The foliage is burned.

Strawberry leaf diseases

Lack of nutrients

Usually, reddening of the foliage indicates nitrogen starvation. In this case, it is worth feeding the plant with nitroammophos (another name for azofosk), ammonium nitrate.

Azofoska is introduced in spring and summer. The month of June is suitable. It is allowed to embed granules in the soil or dissolve them in water. If the first method is chosen, then 25-35 grams should be scattered per square meter of soil. facilities. After the garden bed is watered.You can dissolve a matchbox of nitroammophoska granules in a 10 liter bucket of water.

A good time for ammonium nitrate is the first half of the season. It is scattered into shallow trenches between the bushes. Dosage - 10 gr. one square meter.

Another reason for the sudden redness of leaves is a lack of phosphorus. In this case, superphosphate is added. They can process the garden bed three times per season. Fertilizer interacts well with organic matter. 35 gr. superphosphate is mixed with a glass of fly ash and a solution of cow dung. A solution of cow dung is prepared from 7 liters of water and 1 liter of manure. Such feeding will not only provide the culture with phosphorus, but also make the fruits much sweeter.

Superphosphate for groundbait

Too acidic soil

The foliage may turn red due to the increased acidity of the soil. The culture normally develops only in the ground, the pH of which is 6-6.5 pH. Such soil is considered slightly acidic, neutral. To lower the acidity of the soil, dolomite flour and ash are embedded in it. About one glass per square meter.

Brown spot

The causative agent of the disease is the fungus Marssonina. Signs of brown spot appear in spring and summer both on leaf blades and on berries. The foliage can become covered with spots, the color of which is red, brick-brown, dark brown. The spots increase in size every day. Brown foci are visible on berries, crop stems. Similar symptoms of brown spot are observed in the cucumber garden. Cucumber often suffers from this disease.

Fungus Marssonina

Strawberry brown spot treatment involves both modern methods and folk.

If there is a suspicion of a fungal infection, strawberries should be treated with a manganese solution, as well as Bordeaux liquid (3%). Instead of these funds, you can take copper oxychloride. The disease is treated with systemic contact fungicides Oxyhom, Skor.

Important! It is not recommended to use chemicals at the time of berry formation and before harvesting, otherwise strawberries cannot be eaten due to the possibility of poisoning.

The popular method of combating brown spot is the preparation of an invigorating cocktail, harmful to the Marssonina mushrooms. Take a 10-liter bucket of warm water. 5 gr is added there. potassium permanganate, 4 teaspoons of soda, 10 ml of iodine, 25 gr. laundry soap. Everything gets mixed up. Each leaf is sprayed with a solution. This remedy is good because it allows you to fight spotting at any time of the growing season.

Strawberries have brown spots

If strawberries develop brown spots at the end of summer, then the plant may have developed angular spotting. Other names for the disease: brown spot, bacterial wilting.

  • Fufanon;
  • Intavir;
  • Karbofos;
  • Rovikurt;
  • Aktara;
  • Confidor, etc.
