The reasons

What could have caused the situation when the berries turned brown, acquired a brown-yellow color, became leathery, mummified and bitter in taste? Most often, the fruits are hard and harden when the plant is weakened and influenced by environmental factors. Consider the most common causes of drying.
Fungal diseases of strawberries
Often the plant is attacked by spotting, gray rot, powdery mildew, black rot of fruits, late blight. The appearance of strawberry rot is the result of an insufficient amount of light and heat, poor care, the spread of fungus from an infected bush to a healthy one. These diseases are extremely dangerous, as they quickly spread not only to the berries, causing them to become unusable, but also to the plant as a whole.
Ignoring the treatment of infection is the reason why many gardeners lose their harvests.
Improper watering and lack of normal ventilation
First of all, after the discovery of the situation that the fruit on the strawberry ripens and immediately dries out, you need to check whether the plant receives enough moisture. A large amount of liquid culture requires not only at the time when its fruits are poured, but also throughout the entire period of fruiting. The lack of moisture can be seen by assessing the appearance of the plant. In such a strawberry will be dry and small fruits, as well as foliage. The need for watering is indicated by cracks in the soil and its dryness.
Presence of pests
The reason why the strawberry is brown and does not blush can be hidden in the attack of the parasite. The most common pests include the following insects.
- Stem nematode. During the attack of the pest there is a lag in growth, thickening of the foliage, its wilting and twisting, death of flowers and deformation of the ovaries. Those berries that have been formed stop growing and dry out.
- Earthen mite This pest begins to activate in early spring, when the plant is still weak. As a result, the culture becomes ill, and the fruits are small and dry.
- Raspberry-strawberry weevil.
Lack of trace elements and minerals
You can determine this cause by yellowed and dried berries.
How to fix the problem?
If a fungal infection is found on a strawberry bush, it should be immediately destroyed. using effective drugs and methods:
- gray rot - “Switch” or “Horus”;
- black root rot - digging out a plant with a root system and treating the soil with a disinfectant;
- black rot it is impossible to cure the fruits with preparations; for its liquidation, the diseased berries are broken and burned;
- late blight - proper preventive measures;
- powdery mildew - spraying the foliage with mineral fertilizers, as well as treatment with "Topaz" during flowering.
Pests that destroy the plant, sucking all the juice out of it - this is the reason that should be quickly eliminated, so that the berries do not dry and do not darken. If the parasite was found in the springtime, then it is necessary to spray the plant with Malophos and colloidal sulfur. Insecticides, in particular “Inta-vir”, help from weevils. A one-time chemical treatment may not destroy all insect pests, so re-spraying is advisable.
Do not forget about watering strawberries in hot and dry summers. The important point is that excessive moisture should not be tolerated either, since excessive moisture contributes to the activation of various bacteria. Many of these microorganisms provoke the development of diseases, during which the berries become hard and unsuitable for consumption.
Emergency top dressing of strawberries is what needs to be done if the soil is poor and has not been fertilized for a long time, and the crop does not bring the desired result. Nitrogen and magnesium fertilizers will help to save the situation, magnesium sulphide gives a good result.
To feed the soil you need to start only when you know for sure that the plantation is not infected with a fungal infection. If the plants are diseased, then fertilizer can aggravate their situation.
