Demand for soil
In hydrangeas, the requirement for soil is quite specific - almost all varieties like acid soil, while water-absorbing and air-permeable. To achieve this, it is necessary to introduce peat and humus into the soil. In no case can not add lime, which "extinguishes" acidity. From this, the decorative nature of the plant will suffer.
In addition, on neutral soil, the plant can get chlorosis - yellowing of the leaves. This is due to low absorption of iron under similar conditions. Also, asking the question - what to fertilize the hydrangea hydrangea, it is necessary to assimilate that it is impossible to add nitrogen to the fertilizer during the winter, as this will worsen the winter hardiness of the plant.

Earlier varieties are fed since August. They finish their growth by this month, so that watering is reduced and reduced to "no" so that they can mature on new buds for the next year. During the maturation of the kidneys, in early September, early varieties of hydrangeas are given preplant fertilizing in order to accelerate the flowering period. After pruning, fertilizer is not produced until new shoots appear.
What to fertilize hydrangeas in the fall?
