Despite careful care of zucchini, every gardener has more than once encountered the problem of vegetable rotting. Vegetables can rot for various reasons. In order to eliminate the problem, it is necessary to carefully review the methods of caring for the plant.
Among the most common reasons that lead to rotting of zucchini, several main ones should be highlighted.
Frequent rains
Zucchini prefers humid weather conditions. However, with frequent watering and regular rains, the fruit begins to rot. In order to prevent this problem, it is necessary to reduce the amount of watering.
Failure to maintain distance between bushes
One of the common mistakes is incorrect placement of bushes in the garden bed. A distance of at least 50 cm must be maintained between plants. Since the crop develops quickly and can prevent the fruits from ripening with its leaves. Lack of sun and oxygen often causes fruits to rot.
In order to eliminate the problem, it is recommended to remove some of the leaves. In advanced cases, bushes that grow too close to each other are removed.
Incorrectly selected fertilizer
Often, zucchini begins to rot due to a lack of nutrients in the soil. The rotting process begins if the fertilizer does not contain elements such as boron and iodine. In order to prevent such a problem, it is recommended to use complex minerals.You can also spray the bush with a solution of boric acid. To do this, 2 grams of granulated powder are dissolved in 10 liters.
Diseases
Zucchini ovaries can rot as a result of diseases. These include:
- powdery mildew - manifests itself in the form of plaque on leaves and shoots. Not only the shoots are damaged, but also the fruits. The tip of a young squash begins to turn yellow and rot;
- gray rot - the disease manifests itself as darkening of the ovaries;
- blossom end rot - the disease manifests itself in the form of darkening of the leaves. Black spots are visible on the fruits.
When the first symptoms of the disease appear, it is necessary to treat the bushes with drugs such as Topaz, Fitosporin. Traditional methods of treatment can also be used, which include wood ash, garlic tincture or a light solution of manganese.
Low temperature at night
Zucchini grows actively at night. However, cold nights most often lead to rot. Also, low temperatures can lead to a lack of new ovaries.
Proper care is the key to a large harvest. In order for zucchini to grow evenly, without signs of rot, it is necessary to water the plant with warm water and regularly fertilize it. Maintaining the distance between bushes is also of great importance. Thickened plantings can negatively affect the condition of vegetables and reduce the speed of their ripening.
