White hydrangea prefers well-lit areas with light afternoon shade and protection from strong winds. The best place for planting shrubs is an area next to any building or tall trees.

Soils for common white hydrangea are best neutral or slightly acidic, fertile and loosened. You should not plant a shrub on strongly acidic or calcareous soils, in both cases the culture will develop worse and, moreover, may change the color of the flowers.

Shortly before planting the shrub, the soil in the selected area must be dug up and humus, peat and sand must be added to it. If the soil is highly acidic, you can add a little dolomite flour to it to bring the pH closer to neutrality, but you need to observe the measure.

It is recommended to plant shrubs on neutral soil.

How to plant a white hydrangea

It is recommended to plant shrubs in the ground in May, after the return frosts have passed and the ground has warmed up. Over the summer, the white hydrangea will have time to take root well and will calmly endure the winter. In autumn, the plant is planted only in southern regions, where winter temperatures remain warm enough.

Algorithm:

  1. A planting hole for a white hydrangea is dug in advance, about a month before planting. The hole should be about 50 cm in width and depth.
  2. The hole is half filled with specially prepared soil, usually coniferous soil is mixed with humus and peat and a little sand is added for greater looseness.
  3. Complex fertilizers are applied to the hole - nitrogen, potassium and superphosphate, which will help the white hydrangea to take root faster.
  4. Immediately before planting, the seedling is soaked in water for a couple of hours and its annual shoots are shortened by several buds.

After that, the seedling is placed in the center of the dug hole, the roots are straightened inside it and sprinkled with the remnants of the soil mixture, leaving the root collar above the ground. The soil is lightly tamped, then watered abundantly with 2 buckets of water and the trunk circle is mulched with tree bark or sawdust.

The plant loves nutritious soil with the addition of humus and peat

Advice! When planting several white hydrangeas, leave 80 cm of space between the bushes.

Watering and feeding

White hydrangea loves moisture, so it needs additional watering. In dry weather, it is necessary to pour 20 liters of water under the bush weekly, and the moisture should be clean and slightly warm, the plant does not like cold water. If the summer is rainy, then the shrubs are moistened 1-2 times a month, but at the same time they make sure that the soil at the roots does not dry out.

It is recommended to feed the shrub three times a year:

  • in early spring - nitrogenous fertilizers and organic matter;
  • before flowering - superphosphate;
  • at the end of summer - potassium sulfate or chicken droppings.

It is recommended to carry out top dressing from 3 years of age, since at first the white hydrangea has enough fertilizers applied during planting.

It is not recommended to fertilize white hydrangea in the garden with wood ash. But you can add a little potassium permanganate to the water, such a solution will protect the culture from fungal ailments and increase the frost resistance of the shrub.

You need to water the shrub often - every week

Pruning

Since the white hydrangea grows quickly, it must be pruned every spring. The procedure is carried out in early spring, before the beginning of the growing season - diseased and old shoots are removed, and young branches are shortened by 5 buds.

In the first 2 years in the spring, when pruning, it is advised to remove small buds from the shrub. This will allow the plant to devote all resources to building roots and green mass, so it can subsequently bloom more abundantly.

Important! For old bushes of white hydrangea, cardinal pruning is used, simply remove all the stems at the root and wait for the plant to release new young shoots.

How to prepare a white hydrangea for winter

The winter hardiness of the white hydrangea is average, although some varieties successfully tolerate severe cold and can grow even in Siberia. But in any case, it is customary to cover the plant for the winter, and they do it as follows:

  • with the onset of autumn, the faded inflorescences are removed, and the branches of the bush are bent to the ground and tied;
  • the shrub is covered with agromaterial, burlap or spruce branches;
  • the trunk circle is mulched with peat or compost.

Before winter, wilted inflorescences are removed from the plant

Small bushes can be surrounded by a special frame of the same height as the plant itself, and completely covered with fallen leaves inside it. The procedure is especially recommended for young bushes that are vulnerable to winter frosts.

It is not recommended to cover hydrangea bushes with a film - moisture accumulates under it, which leads to the development of fungal ailments. They remove the winter shelter from the white hydrangea in March or April, after the warm weather has finally established.

How to propagate a white hydrangea

There are several ways to propagate a hydrangea on a site:

  1. Layers. This method is very simple - it is enough to bend to the ground and fix a strong lower shoot in the soil at the beginning of summer, so that by autumn it will take root well. In the next season, the cuttings can be transplanted to a separate place.
  2. By dividing the bush. The method is suitable for adult plants with a developed root system, in the spring the white hydrangea is dug up and divided into 2-3 parts, and then planted according to the standard algorithm in different areas.
  3. Cuttings. In early spring, you need to cut several young shoots from a hydrangea bush, keep them in water for 2 days, and then root them in a sandy-peat mixture at home. The seedlings are transplanted into the ground in the second year, when they get a little stronger.

The easiest way is to propagate the plant by layering and dividing the bush.

If you wish, you can propagate the white hydrangea using seeds purchased from the store. Planting material is embedded in nutrient soil in pots at the end of winter and before the beginning of summer, seedlings are grown at home, and then planted outside. But seed reproduction is used infrequently, it takes a long time, and may not be crowned with success.

Diseases and pests

The immunity of the white hydrangea is average, but with improper care, the plant can suffer from fungal diseases and garden pests. Most often, the shrub is affected by:

  • chlorosis, the disease develops on calcareous soils and with a lack of iron in the soil, hydrangea leaves begin to turn yellow and fall off prematurely;

    With chlorosis, the leaves become stained and begin to turn yellow rapidly.

  • powdery mildew - with excessive moisture, the plant can suffer from a fungus, in which the leaves become covered with a whitish bloom and begin to wither;

    Powdery mildew is characterized by a whitish fluffy bloom.

  • gray rot - in conditions of waterlogging, the leaves become covered with a gray bloom, and then dry out.

To combat fungi, you must, first of all, remove all affected areas of the shrub, and then treat the plant with copper sulfate or chemical agents, for example, Fundazol.

Of the pests, the danger to the plant is mainly:

  • green aphid, small pests can greatly devour a decorative bush;

    The aphids merge with the green foliage of the white hydrangea, but upon closer inspection, it is not difficult to notice it.

  • nematodes - worms infect all parts of the hydrangea and prevent it from developing;

    It is very difficult to fight nematodes, usually the diseased hydrangea is simply destroyed

  • spider mite - the insect feeds on the leaves and juices of the stem, because of which the plant begins to wilt;

    The spider mite prevents the development of the bush and feeds on the green mass of the plant

  • slugs - garden pests eat up leaves and can cause serious damage to ornamental shrubs.

    You need to fight slugs so as not to lose the entire hydrangea bush.

If, during the next inspection, pests or their larvae are found on the leaves, the shrub is treated with soapy water, garlic infusion or insecticidal preparations.

Conclusion

White hydrangea is a very beautiful shrub that is popular with gardeners. On fertile soil and with good moisture, hydrangea develops quickly and, until the beginning of autumn, pleases the eye with snow-white flowering.
