Luxurious pastel hydrangea caps are equally impressive on garden bushes and much more modest potted plants. Hydrangea flowering - their main advantage - can be fully appreciated regardless of the form of cultivation. After all, the greenery of hydrangeas, although irresistible in its own way, still does not distinguish this shrub from the total mass of plants. Moreover, hydrangeas lose their leaves for the winter. These moisture-loving beauties with a special "elite" status grow well in the home format. They require very careful selection of temperatures, and in general they are demanding on conditions and care, but they also have few competitors.

What is an indoor hydrangea like?

The beautiful hydrangea, which came to us from the mild subtropical climate of China, has long become a true favorite of gardeners. But hydrangeas are valuable both for floristry and as living bouquets in a potted form. Moreover, in the latter version, they are used not only to decorate the garden, but also as a houseplant. True, only one type of hydrangea can be called indoor - the large-leaved hydrangea.

Large-leaved indoor hydrangeas (Hydrangea macrophylla) are rarely called by their scientific name hydrangea or large-leaved hydrangea, although it is familiar to any gardener. These representatives of the family of the same name (Hydrangeaceae) are large deciduous shrubs, in rooms they are limited to much more modest sizes.

The leaves of hydrangeas are large, light colored, with a muted light green-herbaceous shade. They sit on the shoots in the next order. Their egg-shaped shape with a beautiful pointed tip only emphasizes the subtlety, beautiful matte texture and ability to glow in the sun.

Bushes, with proper care, seem thick, although, of course, there is no feeling of a luxurious mass of foliage from hydrangeas. The size of the leaves ranges from 10 to 15 cm; the large-leaved hydrangea fully justifies its name.

The natural height of indoor hydrangeas is from 1 to 1.5 m. But thanks to treatment with inhibitors in flower centers or proper formation, the plants are kept much more compact.

The inimitable bloom of indoor hydrangeas

Indoor hydrangeas do not bloom at the same time as their garden cousins. Unlike the garden beauties loving the middle of summer, large-leaved indoor hydrangeas begin the parade from February-March and by July they finish their flowering. Plants are amenable to distillation, so blooming hydrangeas can be found on sale at other times. By changing the dormant period, you can also regulate their flowering in a home format.

The shape of the inflorescences in indoor hydrangeas can differ significantly even within the same species. There are varieties with inflorescences that resemble perfect balls, there are hydrangeas with flat caps, and there are also multilevel shields. They differ both in the density of the arrangement of flowers, and in the size of the inflorescences - from 5 cm in miniature varieties to more than 20 cm in classic beauties.

In the inflorescences, large sterile flowers are located at the edges, as if closing over the fruiting ones, but in varietal plants the shields seem to be solid and the difference is not noticeable.

Actually, the flowers of hydrangeas are inconspicuous. They are miniature, like a small bead against a background of much brighter, diamond-shaped petals of flat and brightly colored bracts. Hydrangea flowers with their four petals seem almost papery.

The color palette of indoor hydrangeas is somewhat expanded in comparison with large-leaved garden hydrangeas. The thing is that flower centers use different tactics and enhancements, and color changes by artificial treatments that cause pigmentation. Thanks to them, the bush on the counter can surprise with its bright blue, light green and even yellow color. But such unnatural beauties will not be able to please you for a long time and are unlikely to last for the next year.

The natural range of indoor hydrangeas includes white, pink, purple and blue spectra in the softest, pastel variations.

Varieties of indoor hydrangeas

It is better to choose indoor hydrangeas not by the name of the variety, but by the size of the bushes and the color of the inflorescences. Among them, you can find both the brightest and extravagant monochromatic versions of colors, as well as charming watercolor, unevenly repainted cultivars.

The following varieties have become real classics for room culture:

  • Compacta is a low-growing variety with very bright, densely spaced leaves and ball-like inflorescences that change watercolor shades of pink.
  • Blushing Bride is a beautiful variety with delicate creamy flowers and dark leaves, well-branched and medium-sized.
  • Ramars Mars is a compact, undersized variety with very unusual lilac-blue inflorescences that turn from pale light green to blue and purple, darkening over time.
  • Early Blue is a very beautiful variety in which light green inflorescences gradually turn blue.
  • Nikko Blue is a cultivar with globular inflorescences that, under the right conditions, can acquire an amethyst shade of dark blue color. The bushes are very sprawling, often drooping to one side.
  • Europe is one of the most beautiful bluish-lilac varieties with irregular watercolor flowers and very dark, emerald green, heart-shaped, wrinkled leaves.
  • Madame E. Mouillere is an unusual narrow-leaved cultivar with double flowers from three rows of "petals" with a bluish bloom in the center.
  • Soeur Therese is an elegant white variety with light purple and heavenly tints of ball-like inflorescences.
  • Red Link is a warm pink dwarf cultivar with light yellow centers of freshly opened flowers, which seems more graceful due to the slightly loose structure of the inflorescences.
  • Magenta - bright pink, with a raspberry shade of large 30-centimeter inflorescences hydrangea with an unusual cut edge of the "petals". The bushes are powerful, about 70 cm high.
  • Red Sensation is a burgundy, intense raspberry variety that turns wine and purple when grown in acidic soil. Very bright greenery and smaller foliage create a curly effect.
  • Prime is a charming pink-red hydrangea with original yellow buds. Flat inflorescences, as if a continuous shield, lie on very short stems and a cushion of matte dark green leaves. The maximum height is about 25 cm.

Growing conditions for indoor hydrangeas

The key to maintaining hydrangeas and blooming for a long time is the right lighting and temperatures. They do not adapt well to a new place and prefer a stable environment.

Lighting and placement

Even in rooms, hydrangea can grow not only in a brightly lit place, but also in partial shade. Of course, hydrangeas cannot stand strong shading, but diffused light is quite comfortable for them.

Most hydrangeas that do not form into dwarfs do not fit well on windowsills over time. They can be placed both on furniture and outdoor near the window. Bushes cannot stand direct sunlight, they very quickly lead to a loss of decorativeness of inflorescences and foliage.

During flowering, it is better to make sure that the lighting remains soft and unchanged, and the hydrangeas do not change their orientation in relation to the window: turning, moving can be perceived by the plant as stress and cause accelerated flowering.

Lighting during the dormant period for hydrangeas is important, but not in the sense that it is for ordinary indoor plants: hydrangeas should be placed in a dark place or put on caps on bushes, protecting them from light. True, only after dropping the leaves. "Naked" hydrangeas are returned to light only after the beginning of the swelling of the buds.

Indoor hydrangeas are plants that overwhelm their neighbors. They are so massive and attractive that few houseplants are capable of not losing their charm next to them.

But a negative influence is not uncommon: hydrangeas next to crops with glossy leathery leaves, impeccable forms can seem more sloppy and lose some of their aristocratic charm. Therefore, it is better to expose them as living bouquets of soloists, beautiful single decorations. Except, of course, for the company of other hydrangeas.

Temperature regime and ventilation

Moving to closed living quarters, hydrangeas become less resistant to temperatures. They need mild conditions and stable cool temperatures, reminiscent of a cozy garden partial shade under the trees.

Hydrangeas look, develop and bloom best of all, which from March to October stay in moderate room temperatures no higher than 20 degrees. A range of 18 to 20 degrees is fine for them. The higher the temperature, the faster the hydrangeas will bloom and the less they will reveal the beauty of their leaves.

The dormant period for hydrangeas should be cool. The maximum permissible temperature for wintering a plant is plus 10 degrees. Optimal - about 5 degrees Celsius. Only after wintering in the coolness can hydrangeas bloom, and the quality of their flowering directly depends on comfortable and stable temperatures.

You can find a suitable place for indoor hydrangeas during wintering both in cellars, basements, cold greenhouses, and between frames or in a cold foyer.

Hydrangeas, as true garden plants, will not refuse to move under the open sky for the summer. Placing them on balconies or in the garden is optional, but highly desirable.

If you decide to leave the beauties in the room to admire their inflorescences, then they should not suffer from a lack of fresh air. Airing should be neat, and with constantly ajar doors, it is worth taking measures to protect the bushes from drafts.

If hydrangeas are planned to be transferred into the soil or there is a large collection, they can also winter in the soil - dug in, under an air-dry shelter, or together with garden tubs.

Hydrangea care at home

Indoor hydrangeas are among the most difficult to care for. Without experience, you cannot cope with them, the bushes are unlikely to be preserved, and the flowering can be extended to six months. There are no unimportant points in caring for hydrangeas.

Watering and air humidity

The substrate in pots with indoor hydrangeas should never completely dry out - even during the winter. In accordance with the decrease in temperature, watering is reduced, maintaining very light soil moisture with small portions of water.

During the period of active growth, indoor hydrangeas require rather active watering, between which only 2-3 upper centimeters of the substrate would dry out. In this case, it is important to avoid dampness, but to maintain an average, uniform humidity.

In the spring, when hydrangeas build up their leaf mass, they consume an astonishing amount of water, so watering is usually done more abundantly just during active growth.

Water quality for indoor hydrangeas must be monitored. It should warm up to the same temperature as the air in the room. Only soft water is suitable for these shrubs. If in doubt about its quality, it is better to slightly acidify the water to prevent alkalization. Hydrangeas grow well when watered with melt water.

Hydrangeas cannot stand heat and love medium humidity. If temperatures exceed a comfortable range, in order to maintain the beauty of the leaves in the crown, it is better to take care of humidifying the air and maintaining humidity indicators at least within 55-60%. Hydrangeas can be sprayed with a foggy method, they will not give up all types and artisanal moisturizers.

Top dressing and composition of fertilizers

Indoor hydrangeas are fed only from March, when the duration of daylight hours begins to increase, and continue to be carried out not only until the end of flowering, but also until the end of October to lay high-quality buds. The classical frequency of 1 every 2 weeks requires a halving of the fertilizer dosage.

If you use the full dose, then it is better to apply fertilizing every 3-4 weeks. It is worth starting feeding in early spring and finishing in mid-autumn gradually.

All hydrangeas, without exception, prefer special fertilizers for rhododendrons. For indoor beauties, you should not experiment with the composition of fertilizers, because even preparations for flowering shrubs are not suitable for them. By reducing the dose, you can use a special fertilizer for garden hydrangeas. Organic fertilizers for indoor plants are not applied.

The luxurious blue colors in indoor hydrangeas can only be preserved in the same ways as in garden hydrangeas - by maintaining the correct acidity of the soil. Special fertilizers for blue hydrangeas, containing aluminum or simple alum, which are added instead of the usual dressing, will help to enhance the much desired heavenly colors.

They are used according to the manufacturer's instructions, strictly observing both the dosage and the frequency of these procedures. But it is worth remembering that blue colors can only be achieved with "colored" hydrangeas - purple or pink, and whites never change to blue.

Another trace element, the lack of which indoor hydrangeas are very sensitive to, is iron. When studying the composition of dressings, you should make sure that it is present in the list of elements.

Pruning and shaping hydrangeas

The rapid growth rates often come as a surprise to those who buy indoor hydrangeas without studying their features. These shrubs develop and grow at an astonishing rate even on windowsills. But hydrangeas need pruning not for compactness, but for flowering - without it, these beauties will not bloom.

Pruning on room-sized hydrangeas should be done immediately after flowering. With late pruning, hydrangeas will bloom much poorer, or they may not bloom at all. Standard pruning is done at 1/3 of the branch height. If hydrangeas stretch out in spring, the young twigs grow too quickly, they are re-pruned to contain and compact.

Sanitary cleaning on hydrangeas should be done regularly. Removing dry leaves, damaged parts, weak shoots, cutting off inflorescences as they wilt are needed not only to maintain a neat appearance, but also to maintain health and reduce the risk of damage to the bushes.

All indoor hydrangeas, as a rule, have much more stable shoots and do not fall apart under the weight of the inflorescences. But if there are signs of sagging of the branches and their poor stability, it is better to tie the bushes to the support.

Transplant, containers and substrate

Unlike many indoor plants, hydrangeas should not be transplanted in early spring when they start to grow. The best time to transplant these beauties is after flowering and pruning. If you postpone the transplant until February-March, during the most important period for the preparation of flowering, the hydrangea will have to face new conditions and move on to adaptation, because of which it may not bloom at all.

But the requirement to transplant after the plant fills the old pot with roots is better for hydrangeas to break. They are transplanted annually, growing in sufficiently compact containers that allow them to develop throughout the year. Hydrangeas prefer wide and shallow pots.

Hydrangeas are one of the indoor plants that are extremely sensitive to the reaction of the soil and its quality. Even the slightest differences from the preferred pH values or unusual deviations in the new substrate are manifested primarily in the colors of the plant: hydrangeas bloom differently in different conditions.

To fully appreciate the characteristics of the variety and the color gamut of the plant, it is worth growing hydrangeas only in a special substrate for rhododendrons. This is especially true for hydrangeas with a cold palette of colors - blue, purple, blue-violet shades. Any hydrangeas feel uncomfortable in the soil, the pH values of which go beyond 4-5.

Hydrangeas are handled very carefully, without contacting the roots and without destroying the earthen coma. After planting hydrangeas, abundant watering is carried out. It is better to keep the plant in high air humidity, very “mild” temperatures and light until growth resumes and adaptation is complete. Drainage at the bottom of the tank is required.

Indoor hydrangeas prefer mulching the substrate - both clean peat and decorative mulch (which does not obstruct air access to the roots) are suitable.

Diseases, pests and problems in growing hydrangea

Indoor hydrangeas suffer only in the wrong conditions of maintenance and with insufficient care. Spider mites and aphids usually affect bushes that suffer from insufficient moisture, but rot - when the substrate is damp. Any deviation in temperatures, feeding, watering, lighting leads to a change in leaves and a slowdown in growth.

When taken out to the balcony and into the garden, the plant may be affected by powdery mildew. It is better to deal with problems by combining correction of conditions and treatment with insecticides or fungicides.

Reproduction of hydrangeas

Indoor hydrangea bushes are rarely propagated, most often preferring to use garden plants as a "material". Meanwhile, only special indoor varieties retain their compactness, branchiness and are much better adapted to not being kept outdoors. If possible, then it is better to propagate initially indoor hydrangeas.

The only breeding method that is used for indoor hydrangeas is by cuttings. To do this, use apical cuttings from young twigs, which grow actively in spring. Green cuttings root better than semi-lignified ones.

You can start grafting hydrangeas from January-February, the deadline is April. For indoor hydrangeas, the standard is a cutting with a length of 8 to 10 cm. Rooting is carried out in a peat-sandy substrate, with constant soil moisture and under a hood. Plants are planted in individual containers.

Separation of bushes, as well as separation of offspring on indoor bushes, is permissible, but only parts with at least 3-4 shoots can be separated. Plants do not tolerate contacts with their roots well and then adapt for a long time.

Garden bushes can also be propagated by layering to produce offspring that could be used in rooms.

Hydrangeas are rarely grown from seeds. Sowing is carried out superficially, under the film, with thinning and diving at the stage of the third leaf into individual containers.
