Watering and humidity
At the end of summer, plants should be watered abundantly. Irrigate the soil every week, using 30 liters of water per 1 m². This allows the root system to harden and develop in order to easily resist frost. It is also necessary to irrigate the crown of the bush to make it magnificent. Surface spraying is carried out every 3 days.
Important! Before watering, loosen the topsoil to normalize the moisture level. Such actions will also help prevent rotting of the root system.
Feeding and mulching
In August, the last summer feeding is carried out. For this, potassium nitrate and superphosphate must be used. Mineral fertilizers will help not only to extend the flowering period, but also to normalize the development of rhizomes. Superphosphate will help make the crown lush. It is necessary to make 40 g of the substance for each bush. For the root system to function properly, use 50 g of potassium nitrate per plant.
After the soil is moistened and saturated with nutrients, it is necessary to mulch the top layer of the earth. To do this, it is recommended to use spruce branches or fallen leaves. Thanks to such actions, the optimum moisture level will be preserved inside the soil, and you can also protect the root system from hypothermia.
For reliable protection of plants from diseases and frosts, it is recommended to use a complex of organic fertilizers. Agromax, which has a long-lasting effect, has proven itself best. Under each bush make at least 60 g of the drug. You can also use peat or compost, using 30 g of fertilizer per 1 plant.
Important! Before fertilizing, you must also loosen the topsoil and remove weeds. Thus, nutrients penetrate the soil better.
In late July or early August, trimming should be minimal. It is recommended to remove only dry and damaged branches that take too much nutrients. In addition, branches growing inside the bush should be removed to thin out the crown. Mass trimming of hydrangea is not recommended.
Care in the fall, wintering
In the fall, every gardener should make every effort to prepare the plant for winter. First of all, you need to cut the damaged branches again to enhance the immune system of the bush.
The preparation of panicled hydrangea for winter consists in hilling. Despite the high frost resistance (up to -30 ° С), sheltering the root system will allow preserving hydrangea blooms in spring. The best materials for hilling are peat and rotted manure. The height of the shelter should be 15 cm.
Diseases, pests and their control
Hydrangea can periodically be affected by various diseases and pests, which spoil not only the appearance of the bush, but also provoke the death of the plant. If untimely to fight them, then you can not save the flower, and the flowerbed will lose its attractiveness.
Treatment for diseases and pest control consists in spraying shrubs with insecticides and other chemicals. The main condition is to observe the time interval so that bacteria and fungi do not have time to develop.
The disease develops due to a lack of iron or an excess of lime in the soil. Chlorosis is manifested in the form of yellowness and dry leaves, while the color of the veins is preserved.
The disease can affect only part of the leaf plate or capture it in its entirety.
If the cause of the disease is an increase in lime in the soil, then the treatment is as follows:
- Add peat or aluminum sulfate (3 kg per 1 m²).
- Water the plants with rainwater.
- Reduce the amount of mineral fertilizer used.
If chlorosis has arisen due to a lack of iron, then you need to irrigate with a solution of iron sulfate (2 g per 10 liters of water). In addition, water should be softened with citric acid. For 10 l use 4 g of powder.

If you do not start treatment at the right time, then the affected areas become thinner and dry.

Symptoms of the disease (gray coating on the leaves or soft tissues) are manifested due to excessive waterlogging of the soil. The reason may also be the density of the crown.
Treatment takes place in several stages:
- Remove the affected parts of the bush.
- Spray the plant with manganese solution (1 tsp. In 5 l of water).
Alternatively, you can treat with a solution of Fundazole (40 g per 5 l of water). If the disease affects most of the bush, it is necessary to eradicate it until the symptoms have spread to neighboring plants.
Leaf spotting appears as ring-shaped spots. After some time, the leaves become deformed and fall off. It is impossible to get rid of leaf spot by chemical or folk remedies.
It is necessary to completely destroy the plant, so it is better to direct all efforts to the prevention of the disease. It consists in the treatment of bushes with a solution of Bordeaux liquid (10 g per 10 liters of water).
The main reasons why powdery mildew develops are an increased level of nitrogenous substances and a lack of watering. The symptomatology of the disease manifests itself in the form of yellow-green spots on the surface of the leaves.
