Growing hydrangeas in the garden


If you decide to decorate your garden with hydrangeas, keep in mind that there are many types of this beautiful shrub.

And almost every one of them requires individual care.

Most types of hydrangeas love warmth. In the middle lane, only a few species of plants are cultivated, which are distinguished by frost resistance. These include large-leaved hydrangea (garden) and paniculate.

Garden hydrangea

Garden hydrangea is called a large-leaved hydrangea. This is the most common type, although many growers hesitate to grow it in midland gardens. The reasons for this attitude towards garden hydrangea are:

  • low frost resistance;
  • the need to preserve the upper buds of last year's shoots.

In addition, autumn and spring frosts sometimes damage flower buds, and then hydrangeas do not bloom.

It should be noted, though, that most hydrangeas under cover do well in cold winters.

In recent years, frost-resistant varieties have appeared that can withstand temperatures down to -35 degrees.

Large-leaved hydrangea loves acidic soils. Take a closer look at what plants grow on your site with pleasure, and you will determine the degree of acidity of the fertile layer: pine, spruce, horsetail, strawberries, caustic buttercup, sorrel and oxalis will indicate an acidic soil.

Hydrangea paniculata

This plant with luxurious pyramidal inflorescences is the most unpretentious plant among its sisters.

She feels great in open sunny places, but agrees to grow even with a little shade, as long as there is no wind.

It is not particularly demanding on soils: it grows on sandy, well-moistened soils and on clayey (but subject to the organization of high-quality drainage).

Panicle hydrangea is not very demanding on the acidity of the soil. Only overly alkaline inhibits it.

Planting hydrangeas

If you got a seedling in late autumn, then he will have to spend the winter at home:

  • small - on a window with good natural light;
  • large - in a frost-free cellar.

The most suitable time for planting hydrangeas is early spring. The planting hole is prepared 2-3 weeks before planting.

Before proceeding with planting, you must complete the following steps:

  • Shorten roots slightly.
  • Cut off annual shoots, leaving 3-4 pairs of buds.
  • If possible, add one part of peat mixed with rotted coniferous litter and one part of rotted compost to the planting pit. The first mixture will give the soil airiness and acidify it, and thanks to the compost, the plant will receive nutrients.
  • Water the planted plant abundantly.
  • Mulch the soil around the plant with compost. It is advisable to mix coniferous litter, pieces of pine bark, rotted cones to it.

Experienced flower growers assure that with a good organization of watering, hydrangeas grow anywhere. But they bloom longer in partial shade: these wonderful flowers do not like either bright sun or thick shade. In addition, the location of the plants must be protected from the wind: the shoots of hydrangeas are fragile, and the inflorescences are heavy.

Preparing plants for winter

There are many agricultural techniques to help increase the frost resistance of hydrangeas:

  • the soil under the plant should be loose: this contributes to its faster thawing in spring;
  • before wintering, it is necessary to saturate the hydrangea well with water;
  • in the fall, it is imperative to add phosphorus-potassium fertilizers.

Panicle hydrangea does not require winter shelter. And the large-leaved one must be reliably covered for the winter. How it's done?

  • The center of the bush is covered with sawdust and peat.
  • The branches can be pinned to the ground, and the bush can be completely covered with earth.
  • Cover the prepared plant with a box or box on top. You can cover the hydrangea with spruce branches, lukrasil.
  • But never cover it with plastic wrap!

But the most important thing is the right choice of the variety for the area.

Proper care of hydrangeas

The plant is greatly benefited by monthly watering with a weak solution of potassium permanganate: this procedure has a firming effect on the hydrangea.

Watering with slurry will also benefit your pet.

In spring and early summer, acidic fertilizers (potassium sulfate, ammonium sulfate) should be applied under the bush. But at the end of summer and autumn, hydrangeas will need phosphorus-potassium fertilizers (superphosphate). 2-3 buckets of nutrient solution should be added under one adult bush.

Pruning hydrangeas

Many growers believe that large-leaved (garden) hydrangeas do not need to be cut at all. They only remove old, weakened and damaged branches. Moreover, they do it at any time. But to form the crown of this species, you need to do the following:

  • in the first year after planting in the fall, shorten the main growths, leaving one or two strong buds;
  • thoroughly mulch with humus;
  • in October-November, cut off only the weakest or those breaking symmetry, because during the growing season several powerful growths and many side branches are formed on the main shoots;
  • in the second year, after flowering, cut off all generative shoots;
  • in the third year (as well as all subsequent ones), immediately after the hydrangea has faded, remove all faded shoots on healthy growths located below and cut out all weak branches. If the bush is very thickened, it is necessary to cut out a quarter of all old shoots to the base.

Paniculata hydrangea can be pruned in autumn, winter and spring. But you shouldn't do this every year. During pruning, small, weak branches are removed, as well as intersecting or rubbing. Strong branches are shortened to 25 cm.

You can form a plant in the form of a tree on a low trunk. To do this, a two-year-old bush must leave the most powerful shoot, completely cutting out the remaining branches.

The next year, shorten this shoot to the strongest bud.

Leave only 2-3 of the shoots that have grown in a year. The next year, cut off the shoots that have developed on them into 2-3 eyes. It will take you eight to ten years to form a tree.
