Florists often ask themselves: why hydrangea does not bloom in the garden. This culture is picky about growing conditions. A small oversight in leaving can provoke wilting and dropping of buds, or even their absence at all.

To ensure long and generous flowering of young and mature bushes, you need to know what circumstances affect their flowering. Knowing why the hydrangea does not bloom, but gives only foliage, you can effectively eliminate the problem when it occurs.

Hydrangea did not bloom

Hydrangeas thrive in moist but well-drained soil in a cool, semi-shady part of the garden. Avoid places where cold winds can damage the growth of young plants, and avoid dry, sunny areas.

Perhaps the plant is still very young. How many years does hydrangea bloom? Some varieties - only in the third or fourth year after planting. It happens even later. Usually, novice growers make gross mistakes in plant care.

Common mistakes:

  • improper preparation for winter;
  • incorrect pruning in the fall;
  • improper watering;
  • the acidity of the soil is not taken into account;
  • violation of the feeding regime;
  • insufficient lighting.

Important! Sometimes pathologies of growth or development of rhizomes are observed, most often in new plants. This entails a deterioration in the development of the bush and an inability to bloom.

How to make bloom

Hydrangia of all kinds and varieties love moisture. Mature shrubs are the most demanding for lighting and tolerate cold much easier than young ones. They are strict in nutritional value and soil composition. Sandy and calcareous soils are unacceptable for them. All this must be taken into account when choosing a landing site. Hydrangea feels good, grows quickly on clay soils. It forms much worse on red earth.

The following techniques will help the culture gain strength and reveal its beauty.

Pruning

Why and when do you need to prune: in spring or autumn? It depends on the species of the plant. According to the type of flowering, Hydrangia are divided into two groups. The first group includes large-leaved varieties, the second includes paniculate and tree-like.

On the shoots of the current season, the bushes of the first group bloom, and on last year's - the second.

Pruning

On large-leaved hydrangia in the fall, you need to partially cut out old branches at the root. Then, next season, powerful replacement shoots will form, they will give good flowering. The task of the autumn cut is plant reorganization and its rejuvenation.

On the treelike hydrangia, inflorescences form on the shoots of the current season. Therefore, they cut it in early spring. In mature and strong plants, 3/4 of the shoot is cut off, keeping up to 5 buds. All frozen and weak shoots are removed at the same time. In the fall, remove all wilted buds and damaged branches so that in winter the snow does not break the shrub.

On a note! The paniculate view can be arranged as a small tree on a low trunk.

Pruning is carried out in the spring: all branches that are frozen, weakened and growing towards the middle of the bush are cut off. Young growth is pruned, leaving up to 10 buds. All inflorescences are removed in autumn.

Preparing for winter

In colder regions, when a cold snap hits, many gardeners take steps to protect hydrangeas in winter.

Treelike is the most frost-resistant species, therefore, shelter is needed only for young seedlings that came from warm regions. In the fall, add several compost buckets under each plant. This will protect the roots from freezing.

Preparing for winter

Large-leaved - not particularly resistant to frost, so it needs to be helped to hide from them. The shoots are laid on boards or coniferous paws and are attached to the ground with metal studs. Then they are covered with crumbling leaves or spruce branches. In the spring, when the threat of frost passes, the shelter can be removed. In order to protect the plant from sunburn, it is better to remove the cover in the evening.

Panicle hydrangea overwinters easily without insulation. You just need to mulch each bush with humus. The plant can bloom for over 50 years. The rejuvenation of the shrub is ensured by its complete cutting under the stump.

Watering

All hydrangias need systematic, generous watering and soil mulching. This is especially important when planting in sunny places or sandy soils. The most drought-tolerant large-leaved hydrangea. Large panicle hydrangeas can easily tolerate a fairly long drought.

Soil acidity

For a garden hydrangea, the most suitable pH level is 5-6. It is strictly forbidden to lime the ground. The acidity level of the soil will gradually decrease during the absorption of nutrients.

Soil acidity

Organic and mineral groundbaits oxidize the soil. If necessary, you can acidify the soil by mixing 10 grams in ten liters of water. food acid.

Often, the desired shade is obtained by artificially altering the soil pH by watering the plant with alkaline or acidic solutions.

Top dressing

Fertilizers are needed for development and lush flowering. There are special hydrangea dressings. Fertilizers enrich the soil not only before planting plants, but also during their intensive growth in order to accelerate it.

Feeding the hydrangeas is definitely part of the puzzle, but if you add too much hydrangea fertilizer, you run the risk of increased leaf growth and very few flowers.

The first feeding should be done in late May or early summer. Then the plants are fed every two weeks. So that the plants can have time to turn numb before winter, from the second half of summer all feeding is stopped.

Tips

  • When laying a hedge, a strip is dug up, 1 m wide. Between the plants there should be 0.7-1 m, after a few years they thin out.
  • In areas with a cold climate, it is advisable to plant hydrangia in early spring. Where there are no frosty winters, you can plant bushes in the fall.
  • Before planting, the roots of the seedling are slightly trimmed.
