Garden plants

Treelike hydrangea (lat.Hydrangea arborescens) - a species of plants of the genus Hortensia of the Hortensia family, found in the wild in eastern North America. This is the most unpretentious and widespread species of the genus, which easily withstands severe winter frosts.

Planting and caring for a hydrangea tree

  • Bloom: profuse, from mid-July to October.
  • Landing: in the spring until the buds swell or fall leaves.
  • Lighting: in the morning - bright light, in the afternoon - partial shade or shadow.
  • The soil: moist, rich, light but fertile, well-drained, with a pH of 5.5.
  • Watering: regular and plentiful, especially in dry season: 1-2 times a week with a water consumption of 3-4 buckets for each plant.
  • Top dressing: in the spring, a handful of Kemira flower is scattered along the near-stem circle, and potassium-phosphorus fertilizers are applied during the budding period. Until the end of the season, you can make 2-3 more fertilizing with fertilizer with a low nitrogen content.
  • Cropping: pruning begins in the fifth year: the main procedure is carried out in the fall, and in the spring they do only sanitary cleaning and once every 6-7 years anti-aging pruning.
  • Reproduction: cuttings, layering and dividing the bush.
  • Pests: spider mites and green leaf aphids.
  • Diseases: powdery mildew, downy mildew (re-sporosis) and chlorosis.

Botanical description

Treelike hydrangea is a shrub with a height of 1 to 3 m with a rounded crown and slightly pubescent shoots. Hydrangea leaves are tree-like, elliptical or ovoid, 6 to 20 cm long, with serrated edges and a heart-shaped base, bare on the underside of the plate. The upper side is green, the lower is gray. A few sterile flowers about 2 cm in diameter, together with small fertile flowers, are collected in shields up to 15 centimeters or more in diameter. At the moment of opening, the white flowers have a greenish tint, then the greenness disappears, and by the end of flowering the inflorescences turn pink. The fruit of a tree hydrangea is a box up to 3 mm in size. The plant blooms profusely and for a long time from the first half of July to mid-autumn.

The culture is distinguished by its rapid growth, love of moisture, exactingness to the composition of the soil and winter hardiness. This species is easier than other hydrangeas to tolerate the presence of lime in the soil.

Planting a hydrangea tree in open ground

When to plant

The planting time of hydrangea tree-like is chosen taking into account the climate of the area. In the north, it is better to plant it in early spring, before the start of sap flow, as soon as the soil thaws in the garden, and in areas with a mild, warm climate, you can plant hydrangea both before the buds swell and after leaf fall.

How to choose the right place for the plant? Hydrangeas prefer areas that are well lit in the morning and shade in the afternoon. The hydrangea does not like the tree-like wind: its flowers in places blown through and through quickly fade. The plant needs moistened soil, so do not plant it close to trees and shrubs so that they do not absorb moisture intended for hydrangea from the soil: the distance from a tree hydrangea bush to any other plant should be at least 2 m.

How to plant

The best planting material is three to four year old tree hydrangea seedlings. When buying seedlings with an open root system, pay attention to its condition, but it is better to purchase planting material with closed roots. Before planting, the seedling is abundantly watered, removed from the container and its roots are shortened to 20-25 cm. If rotten or dry roots are found, you need to cut them too.

When planting in poor soil, a hole is dug with a diameter of about 50 and a depth of 65-70 cm, but if the soil on the site is fertile, then the depth may be less - about 50 cm.In general, the size of the hole depends on the size of the root system of the seedling and the amount of land on it ... In the center of the pit, pour a mound of a previously prepared soil mixture of humus, black soil, sand and peat in a ratio of 2: 2: 1: 1 with the addition of 50-60 g of complex mineral fertilizer. Place the seedling on a mound, spread its roots and fill the remaining space with the same nutritious potting soil. Then tamp the surface of the trunk circle and water liberally at the root of the plant.

Hydrangea tree care

Growing conditions

Treelike hydrangea in the open field requires regular and abundant watering, especially during the dry hot period. In addition, you will need to loosen the soil in the trunk circle and remove weeds, apply top dressing to the soil, prune hydrangeas and protect it from diseases and pests.

Watering hydrangea tree-like is carried out 1-2 times a week with water at a temperature of 20-25 ºC, pouring at least 3-4 buckets of water under each plant. If the plant lacks moisture, its leaves droop and begin to turn yellow, the flowers dry out, and the hydrangea loses its decorative effect. Therefore, make sure that the soil in the trunk circle does not dry out. After watering or rain, the surface is carefully loosened, trying not to damage the root system located at a shallow depth, while removing weeds. To protect the soil from the rapid loss of moisture, you need to mulch the surface around the plant with a layer of peat or humus, in this case you will have to water and loosen the soil, and you will have to weed much less often - about once every 10 days.

In order for the hydrangea to be attractive throughout the growing season, it is necessary to feed it with both mineral and organic fertilizers. In early spring, a handful of Kemira flower is scattered in the trunk circle, which contains not only nitrogen, phosphorus and potassium necessary for each plant, but also a group of important microelements. The second dressing, consisting of 30 g of potassium sulfate and 50 g of superphosphate for each plant, is applied during the budding period. In the future, you can apply fertilizer 2-3 more times, but be careful with nitrogen, as its excess leads to the appearance of a stable green tint in the flowers of the hydrangea. In addition, plants overfed with nitrogen do not overwinter well.

2-3 times in the spring, watering the soil is carried out in the near-trunk circle and the crown is sprayed with a weak solution of potassium permanganate. This is done to enhance the strength of the treelike hydrangea shoots, which may not withstand the weight of a large number of large inflorescences. You can, of course, tie the branches to the support, but this will not add attractiveness to the plant.

Of all the species of the genus, the hydrangea tree is the most unpretentious and cold-resistant, however, new plant varieties brought from nurseries in warm regions require dry hilling and light shelter before wintering. Hydrangea bushes less than four years old are covered with foliage or spruce branches. It is advisable to tie the branches of the bush together for the winter so that they do not break under the weight of the snow. But even if the plant suffers from frost, the tree hydrangea recovers quite quickly in the spring.

Pruning

Treelike hydrangea forms inflorescences on the shoots of the current year. The first four years after planting, the plant is not pruned, but later pruning is carried out twice a year, in spring and autumn. The main one is autumn pruning, during which all wilted inflorescences are removed.

If the hydrangea is not cut, the bush becomes too thick and looks sloppy, neglected. In the spring, before the start of sap flow, they do sanitary cleaning of the bush, removing weak, thin, frozen, dried, damaged and thickening bush, that is, growing towards the center, small or weakened zero shoots incapable of flowering. One-year-old shoots are shortened to 3-5 buds, of which new shoots with large inflorescences will appear this year.

Once every 5-7 years, a rejuvenating pruning of hydrangea tree-like should be carried out: in early spring, all shoots older than five years are pruned at a height of 10 cm from the ground. However, the rejuvenation of very old plants takes three years, otherwise they may die.

Pests and diseases

Treelike hydrangea can be damaged by spider mites and green leaf aphids - sucking insects that feed on the cell sap of leaves and young shoots of the plant. It makes no sense to waste time trying to destroy hydrangea pests with folk remedies, it is better to immediately start treating the shrub with an acaricide solution. They cope well with sucking pests Aktellik, Fitoverm, Aktara, Sunmayt.

Of the diseases, hydrangea tree-like can suffer from powdery mildew, downy mildew (oversporosis) and chlorosis. Fungal diseases are treated with fungicides. For example, when a whitish bloom of powdery mildew appears on the leaves, the hydrangea should be treated as soon as possible with a solution of Bayleton, Quadris, Topaz, Fundazol or another drug of a similar action. For peronosporosis, the plant is treated with biofungicides Gamair, Alirin-B or Fitosporin. The solutions are prepared in accordance with the instructions of the manufacturer of the chemical preparation, strictly observing the dosage and the interval between treatments.

As for chlorosis, which manifests itself as discolored spots on the leaves, it usually arises from an excess of humus in the soil or a lack of iron in it.

Reproduction of hydrangea tree

Treelike hydrangea propagates by cuttings, dividing the bush and layering. Professionals also use grafting and the generative method for this purpose, but for amateurs they are too laborious, expensive and unreliable.

Dividing the bush

It is possible to divide a hydrangea tree bush both in spring and in autumn: the bush is dug up and disassembled in such a way that on each division there are necessarily renewal buds. Parts of the bush are planted in pre-prepared pits. If you carry out the procedure in the spring, by the fall, parts of the bush will already take root in new places.

Reproduction by layering

This is also a fairly easy-to-use breeding method that gives good results. In the spring, annual shoots are bent to the ground, placed in pre-made grooves up to 10 cm deep so that the apical section about 20 cm long remains above the surface. The layering is fixed in this position, and the groove is covered with fertile soil. Throughout the season, the cuttings are watered and fed along with the mother plant, and in the fall or next spring it is separated from the bush and planted in a new place.

Propagation by spring and summer cuttings

This method of propagation of tree hydrangea is used most often. Spring cuttings are cut in early June so that they have a heel at their base - a small part of last year's shoot. Summer cuttings are harvested in July from the apical, non-lignified part of the shoot. The cuttings should have 1-2 internodes. The upper leaves on them are shortened by half, the lower ones are removed. For successful rooting in conditions of high humidity, an installation that produces fog will be required, and a soil mixture of two parts of peat and one part of sand is used as a substrate, although cuttings can also be rooted in leafy ground covered with a layer of sand 3-4 cm thick. Planting is carried out at an angle of 45º, from above the greenhouse is covered with a transparent cap. Rooted cuttings spend the first winter in a cold greenhouse or basement, and in the spring they are planted in the ground. Next winter, the cuttings are well covered with spruce branches, and after a year they can already winter without shelter.

Treelike hydrangea varieties

Not many varieties of tree hydrangea are grown in garden plots. The best ones are:

  • hydrangea treelike Grandiflora - shrub 1.5-2 m high with a crown up to 3 m in diameter. The leaves of the plant are light green, up to 16 cm long. Creamy white flowers up to 2 cm in diameter are collected in corymbose inflorescences up to 20 cm in diameter. Abundant flowering lasts from June to September;
  • Annabelle - treelike white hydrangea up to 1.5 m high, with a crown up to 3 cm in diameter and with inflorescences up to 25 cm in diameter. This variety blooms at the same time as Grandiflora. Annabelle's annual growth is 20 cm;
  • hydrangea tree Pink Annabelle - the shape of the Annabelle variety with dark pink inflorescences that gradually turn bright pink;
  • Sterilis - a variety with flowers, collected in dense hemispherical inflorescences, from the severity of which branches bend. At the moment of opening, the flowers are greenish-white, then the green tint disappears, and the inflorescences remain white until the very end, without acquiring a pink tint;
  • Hayes Starburst - one of the new varieties with narrower leaves than other hydrangeas and with spherical inflorescences up to 25 cm in diameter, consisting of white double flowers;
  • White Dome - bush up to 130 cm high with a beautiful oval crown. The inflorescences consist of small creamy white fertile and snow-white sterile flowers. The variety is winter hardiness, its shoots perfectly withstand the severity of the inflorescences and do not bend;
  • Incredibol - a vigorous, hardy variety, similar to Annabelle, but with even larger globular creamy white inflorescences with a barely noticeable lime-yellow tint;
  • Invincibelle - the very first variety of hydrangea tree-like with colored inflorescences: dark pink flowers open on the plant, and until the end of flowering, only the intensity of their color changes.

Hydrangea tree in landscape design

Treelike hydrangea looks great both in single and in group plantings. It harmonizes wonderfully with clematis, lilies and roses. The plant is used to create woody-shrub compositions in combination with coniferous species of plants, as well as a hedge that does not require formative pruning. No matter how you decide to use a tree hydrangea, it will undoubtedly decorate your site.

Hydrangea: planting and care in the open field (PHOTOS)

We have a summer cottage in the suburbs. Previously, there was a forest rustling, but now it is a shaded forest area with acidic soil. There is little sun, mostly shadow and partial shade. In general, like most, the zone of risky farming. But the thought of making my site beautiful does not leave me. We planted weigela, David's budley, action, but after the first winter the bushes died.

Hydrangea is rightfully called the queen of the garden, just like the rose.

Forsythia, which is in any garden in Germany, and is considered unpretentious, I have a stunted bush and does not bloom.

I thought that we couldn't do anything with hydrangea either. In the spring they planted a tiny bush, and in the first summer it bloomed. How we were delighted with three branches, crowned with snow-white caps. Now the hydrangea, which turned out to be a tree hydrangea, is a huge lush bush with at least a hundred caps. She obviously liked the place and our children's delight in her beauty. We propagated the bush and planted it in other parts of the garden, but there it is much smaller.

But the panicle hydrangea, planted in full shade, immediately died with us. Over the years, I planted several different varieties of panicle hydrangeas. They fascinate us and surprise with their inimitability.Walking this summer with my grandchildren on the territory of our partnership, I saw a lot of hydrangeas with white, pink, red and blue caps of inflorescences on one site.

There is never too much of this amazing flower. Many varieties will surprise us with their diversity. This shrub is rightfully considered the most beautiful and amazing. Its endless bloom will delight us all summer, from the second half of June to the end of September. And in winter, a beautiful hydrangea is magnificent in bouquets. Beauty requires sacrifice, and with a little effort, you can turn your site into a garden of paradise.


Features of the

Pink hydrangea attracts attention with its lush inflorescences. That is why this tree-like bush is so often used both in parks and squares, and in the landscape design of personal plots. This deciduous shrub reaches 1 m in height. The leaves are elongated, emerald green, do not fall until late autumn.

The description of the hydrangea should include a detailed story about its inflorescences. Any species of this plant has a very interesting flowering. Small flowers are located in the middle of the inflorescence, surrounded by larger flowers. This feature gives particular visual interest to both pink hydrangea and other species. Flowering will delight from mid-summer to mid-autumn.

Important! It is the varieties of pink hydrangea that have an amazing feature: its flowers can change color thanks to a special substance - anthocyanin.

If the soil is alkaline, the flowers remain pink. Acidified soil will cause color changes to sky blue.


Hydrangea tree care

A luxurious plant for lush and long flowering needs attention and care from the gardener.

Watering and feeding

Hydrangea is a moisture-loving plant with a shallow root system, which, due to its proximity to the soil surface, often suffers from heat.

In order to prevent the oppression of the culture by drought, watering should be carried out 2 - 3 times during the week.

To strengthen immunity and ensure the formation of lush bushes with spectacular inflorescences, it is necessary to carry out 4 dressings during the growing season:

  1. The first application of complex mineral fertilizers with a high nitrogen content is carried out after the start of shoot growth.
  2. In the budding phase, the bushes are fed with phosphorus-potassium agrochemicals that stimulate long flowering.
  3. The next two dressings are carried out until September, which allows the hydrangea to leave stronger in winter.

Mulching and loosening the soil

After precipitation or moistening, it is recommended to loosen the soil so that an airtight crust does not form. Mulching will reduce the frequency of loosening and will also reduce the rate of moisture evaporation. As a mulch, you can use a layer of sawdust or peat 5 - 8 cm thick.

Attention! When covering the soil with a mulch layer, it is important to ensure that it does not come into close contact with the shoots.

Pruning features

Formative pruning of hydrangea in spring is carried out in March before the first feeding, when the shoots are significantly shortened - strong branches up to 3 buds, and weaker ones - up to 5 pieces. In autumn, all dried inflorescences, as well as broken and diseased branches are removed. In order for the plant to retain its decorative effect over the years, attention should be paid to the haircut and not allowed to thicken.

Important! Hydrangea should not be cut before the crop reaches four years of age and the onset of the first flowering.

How to care for hydrangea in autumn, winter

For the plant to successfully overwinter, it must be properly "preserved" by watering abundantly with warm water 10 days before the onset of frost. Also in the northern regions, despite the frost resistance of the culture, the bushes should be covered with spruce branches, having previously tied the shoots to a wooden stake driven into the trunk circle.

Transfer

When choosing a place for culture, one should take into account the hydrangea's dislike for transplanting, which, if urgently needed, can be carried out in spring or autumn.


Care features

The content of Limelight differs little from other Panicle hydrangeas. It is important not to run the bush, to do everything on time.

Watering

Irrigation should be so frequent that the soil under the hydrangea does not dry out even for a short time. Pour under each bush:

  • 2 buckets of water when short pruning in spring, or Limelight hydrangea grown on a stem
  • if the plant is a multi-stemmed tall shrub - 20 liters for every 1 m of growth.

To preserve moisture, the trunk circle is mulched.

At least once a month, under the Limelight hydrangea, you need to acidify the soil. Use:

  • fermented milk products - 2 liters per bucket
  • wine vinegar - 100 g for the same amount of liquid
  • citric acid - from 1 teaspoon to 2 tablespoons, depending on the pH level of the substrate and whether the owners perform the operation regularly or periodically.

It is recommended to defend hard water or tap water before watering hydrangea.

Top dressing

Limelight is fertilized four times per season:

  • in spring - with nitrogen
  • twice - in the summer, with a full mineral complex with trace elements, during the extension of the buds and during the opening of the corollas
  • in the fall - potassium and phosphorus without nitrogen.

In summer, it is recommended to use specialized fertilizers for hydrangeas and rhododendrons. There, all the nutrients are given in a balanced form. You can give the culture a top dressing for conifers marked "summer".

Before the buds open, Hydrangea Limelight is recommended to be alternately treated along the crown with a solution of mineral fertilizers or chelates every 14 days. This will make the flowering more lush, and the bush healthier - trace elements are better absorbed through the leaves. After the opening of the corollas, the processing is stopped so as not to reduce the decorative effect.

Pruning

In the fall, only peduncles are removed. In the spring, before the start of sap flow, a short pruning is done, leaving 3-4 internodes on strong shoots. Weak or thickening bush is removed completely.

If only sanitary measures are carried out and the tips of the frozen twigs are cut off, the hydrangea will be large, dotted with small inflorescences.

Hydrangea Limelight on a stem is formed as follows:

  1. One strong shoot is left and tied to a peg, the rest are cut out at the root.
  2. When it grows to the desired height, the lateral processes are removed. 3-5 strong branches are left on the crown, from which the crown is formed.
  3. The stem is kept clean, plucking out the awakened buds throughout the season.

Preparing for winter

The first 1-2 years after planting with the onset of frost, young bushes are tied with spruce branches, or tilted to the ground, covered with leaves or needles, and non-woven material is fixed on top.

When the Limelight hydrangea takes root, they only mulch the trunk circle - they fall asleep like a rose bush, but not with earth, but with sour peat or coniferous litter. If the branches freeze, it's not scary - in the spring they will still have a short pruning.


Hydrangea pink large-leaved: features of the species and tips for breeding

For a very long time I did not dare to plant a large-leaved hydrangea in the garden after several unsuccessful attempts. But one day I came across an article about new remontant varieties that I became interested in. I sat down to study the experience of gardeners, I have collected a whole selection of recommendations that I share.

In large-leaved hydrangea, faded inflorescences are not cut off for the winter.

Hydrangea pink large-leaved

Plant in spring or fall

Large-leaved pink hydrangea:

  1. Landing. To plant a large-leaved hydrangea, you will need to prepare a planting soil consisting of peat, sand, humus and garden soil in equal proportions. Despite the fact that the plant is moisture-loving, it does not tolerate stagnant water. Therefore, crushed stone or pebbles are laid at the bottom of the planting pit, then a layer of prepared soil. By transferring a seedling from the pot, a seedling is planted and sprinkled with the rest of the earth.
  2. Watering. After planting, the plant should be well watered with water with the addition of potassium permanganate or a growth stimulant. It is also good to add phytosporin to the water. This measure will protect the plant from many viral diseases. From above, the root circle should be well mulched with needles or sawdust. The plant should be planted no closer than 5 m from deciduous trees.
  3. Care. In subsequent watering, citric acid or vinegar can be added, thus, the necessary acidity will be maintained in the ground. The plant also needs fertilizing, organic fertilizers are best suited. It is not necessary to cut off faded inflorescences, since flower buds of future inflorescences are formed at the ends of the shoots.

Suitable for lawns and flower beds

Discoloration of inflorescences

Hydrangea inflorescences of large-leaved, paniculate and ground cover cream and pinkish color, if desired, can be changed to blue, pale purple or blue. The fact is that the color of hydrangea flowers depends on the acidity of the soil. Pink and crimson flowers are with a slightly alkaline reaction, and they turn blue on acidic soil, while it must be borne in mind that white inflorescences practically do not change their color.

In an alkaline environment, hydrangeas are not able to use iron from the soil, on which the color of flowers depends (this nutrient is absorbed in an acidic environment). To get blue inflorescences on alkaline soils, plants are watered with a solution of iron salts. To enhance the blue color, iron shavings or small iron objects are buried under the bushes. The brighter the initial color of the inflorescences was, the more intense the blue or purple color will be. In some cases, both blue and pink inflorescences can appear on the bush at the same time. The inflorescences can turn blue if the plants were planted in peat soil, but the blue color can become dirty.
