Basic principles of care and growing hydrangea in the garden

When choosing a place to place a hydrangea, it should be borne in mind that it will feel best not in direct sunlight, but in partial shade conditions. It is important to never plant the plant in dense shade or in a draft. Hydrangea is not demanding on the composition of the soil, it grows well even on the poorest soils. The optimal composition is a mixture of equal parts:

  • sand
  • peat
  • leaf land
  • turf land

A slightly acidic environment is preferable. For successful cultivation on alkaline soils, it is necessary to water the plant with a solution of iron-containing salts every two weeks to neutralize the alkaline environment.

The landing pit is prepared a few days before the intended landing. Its size depends on the volume of the root system of the future plant and the height of the shoot. Usually, a hole up to 60 cm wide and up to 40-50 cm deep is enough. A pre-prepared mixture is poured onto the bottom of the hole.

Planting material can be:

  • split bush
  • rooted stalk
  • biennial sapling

Place the seedling in the planting hole in such a way that its root collar is not deeply buried in the soil, but is at its level or a couple of centimeters below, the roots of the plant should not be outside. In case of close occurrence of groundwater, the method of planting on a hill is used.

Covering the roots with soil, the trunk circle is well compacted. After abundant watering, it is mulched to avoid crust formation. In the future, the plant will require abundant watering and regular loosening. When loosening, damage to roots close to the surface should be avoided.

For abundant flowering, at least three times during the summer season, it is necessary to apply mineral fertilizers. At the beginning of the season - nitrogen and potash. In the middle and at the end - phosphorus and potash. Throughout the warm season, hydrangea requires abundant watering. Bushes older than three years of age are regularly pruned.

In addition to general principles, there are individual characteristics of growing and care for various types of hydrangeas.

Some secrets of an individual approach to types of hydrangeas

Four main types of hydrangeas are grown outdoors:

  • paniculate
  • tree-like
  • groundcover
  • sargent

Panicle hydrangea reaches a height of up to two meters. Needs annual early spring pruning of all shoots to about half. The species is frost-hardy and hibernates without shelter. Propagated by cuttings in early summer.

Hydrangea sargent is the most thermophilic of all types. Since the plant is exposed to winter freezing, every autumn the bushes are cut into a "stump" 15-20 cm high. It is additionally covered with spruce branches or other covering material. Prefers well-lit places.

Treelike hydrangea - the tops of the shoots can be damaged by frost, are removed during spring pruning twice: before opening and after opening the buds. To prevent freezing, the bush is covered with spruce branches or other material for the winter.

Ground cover hydrangea tolerates winter well and does not require shelter for the winter. Many people know that if you apply watering with sour alum, you can change the color of the inflorescences. But there is a "popular" way to get bright colors: pour a kilogram of young chopped nettle with a liter of boiling water, insist, strain and add water to a bucket. Watering with "green" fertilizers should be started at the budding stage, before the inflorescences open.

Full care and cultivation are impossible without disease prevention and pest control.

Diseases and pests of hydrangea

The main prevention of hydrangea diseases is timely pruning and removal of excess shoots. Hydrangea, although it is a moisture-loving plant, in no case should water stagnation on the soil surface and its waterlogging be allowed.

If preventive measures were not enough and the plant got sick:

  • powdery mildew
  • gray mold
  • septoria

First of all, it is necessary to take measures to drain the plant, remove and destroy damaged parts and treat with fungicidal preparations:

  • topaz
  • jet
  • pure bloom

Hydrangeas are attractive to pests such as:

  • aphid
  • scabbards
  • bedbugs
  • spider mites

If the attack of aphids is insignificant, then it can be washed off with soapy water, in severe cases, treat the plant with drugs:

  • Tanrek
  • Spark
  • Bison

Suitable against bedbugs:

  • green soap
  • karbofos
  • fufanon

The most difficult thing to deal with is scabies. A small number of them can be collected and destroyed by hand. Otherwise, the whole plant will have to be treated with a kerosene emulsion or other mineral oil. You can fight a spider mite in the same way as with aphids.

For indoor hydrangeas, care is the same as for garden forms. Compliance with the rules of care will make dreams of a beautiful blooming hydrangea a reality.
