While indoor cypresses are competing for the title of "most indoor" coniferous, flower growers turned their attention to a more compact, hardy and diverse cypress. A plant that is winter-hardy even for a garden moves into rooms no less willingly than cypresses, which are beyond our control. And they adapt to the conditions inside the interior much easier. It would be a big mistake to call cypress plants easy to grow - these are species for experienced and scrupulous growers. But these plants are strikingly impressive, healthy and vibrant.

Indoor format of garden cypress trees

Very similar to cypress trees in appearance, cypress trees are a frost-resistant alternative and the only replacement for subtropical and tropical cypress trees in countries with harsh winters. Despite the fact that low frost resistance for room culture is not an obstacle, more and more often not genuine cypresses appear on the shelves, but much more diverse, affordable and popular garden cypress trees.

Cypress trees are ancient representatives of the Cypress family. They are widespread throughout the northern hemisphere. Indoor culture traditionally features the same plants that are used in local landscaping.

Despite the fact that all cypress trees are quite large plants in nature, indoor cypress trees remain compact and medium-sized evergreen trees. Usually only young, immature cypress trees are grown, whose needles are still soft.

Due to the slow growth (2-5 cm per year) in the room format, cypress trees are left up to 10 years. One-two-year-old seedlings and young seedlings that have begun to form a crown are preferred. The younger the plant, the better it will adapt to indoor growing.

The shoots of cypress trees are thin, densely branching, flexible, often bent at the ends, becoming thicker and stronger over time. The brownish-reddish bark is very beautiful, but under the needles it is almost invisible.

Cypress needles, especially at a young age, pleasantly surprise with their softness. Delicate, pleasant to the touch, not at all rigid, densely located needle-shaped needles of young cypress trees also have a rich palette of shades. Even in the simplest, non-varietal plants, the needles are bluish-bluish.

Genuine "adult" flattened, scaly needles in cypress trees appear after a few years, and on older plants the needles sit even more densely. With age, the colors intensify, the upper side of the needles darkens, and on the lower one you can see white spots.

Purifier, Christmas tree and potential garden decoration

All indoor cypress trees without exception can be considered as effective fungicides and the best plants for air purification. They fight not only with toxins, but also suppress disease-causing microbes, in fact, disinfecting the air.

One of the most popular reasons for growing cypress trees as a houseplant is to replace the Christmas tree. Beautiful and neat, fragrant and elegant, cypress trees look great as an alternative to fir trees. But since a warm wintering is not for them, it is not worth bringing the plants into the premises for decoration and use for longer than 5-7 days.

Lost decorativeness, drying out, elongated, overgrown cypress trees can be planted in the garden and try to preserve, observing the rules for garden species. They should overwinter for the first 2 years with an air-dry shelter.

Cypress or cypress?

Confusion when buying indoor conifers cannot be avoided. Even thuja with junipers are sometimes offered to grow as cypresses, to say nothing of the confusion between cypresses and cypress trees that are so similar not only in name.

Some plants are passed off as others, and for many, cypress or cypress is almost synonymous. But still, the type of coniferous acquired is of considerable importance. After all, it determines the changes in the crown with age, and the temperature of the content, and even the requirements for air humidity.

Cypress trees are generally less whimsical than cypress trees, which, with small deviations from the ideal environment, can very easily lose their decorative effect and begin to dry out. Therefore, if you are looking for a more resilient, fast growing, compact version - check the Latin name by choosing cypress (Chamaecyparis) over cypress (Cupressus).

Usually, the species can be guessed at the price: cypress trees at a young age are much more affordable and more common, the cost of seedlings is lower due to the greater popularity of the plant and easier reproduction.

Types and varieties of indoor cypress trees

In the indoor format, cypress trees cannot boast of a species diversity: only a few species are suitable for this form of cultivation.

Most indoor cypress trees are pea cypress trees (Chamaecyparis pisifera). They are represented by decorative forms and varieties with a conical, but inaccurately diverging dense crown at the top or open bushes. Dense, soft needles and a rich choice of colors are their main advantages.

More and more decorative forms and varieties of Lawson cypress trees (Chamaecyparis lawsoniana), in particular, the series of varieties "Elwoodii", which are especially compact. These are slow-growing coniferous conifers with flexible shoots and bright crown colors - gray, golden, white-green.

Indoor cypress trees can be divided into two types of plants:

  1. Common shrubs and trees;
  2. Bonsai.

The growing conditions and the peculiarities of caring for miniature copies of natural giants are no different from the content of the bushes not formed in the mini-version, with the exception of a slightly more difficult pruning.

In all respects from lighting to watering, the requirements for all cypress trees are the same.

Growing conditions for indoor cypress trees

It is believed that all indoor conifers are similar to each other. But still, each type of plant has its own "zest". Cypress trees love fresh air and in potted form require a special choice of lighting mode. But in general, it is easier to find a suitable place for them than for competitors.

Lighting and placement

Many indoor conifers require only bright lighting, but cypress is a pleasant exception. It retains part of its shade tolerance even in living rooms, but varietal plants with original colors are more photophilous than simple green cypress trees.

Direct sun is very dangerous for them, even if it is a matter of several hours in the evening or early in the morning. The degree of shading should be selected individually. Depending on the level of humidity and ventilation, the same plants in different rooms can show both great light dependence and shade tolerance.

It is better to navigate when searching for the correct lighting mode, first of all, by the color of the needles. In the shading of cypress trees, the brightness of the colors is muted, but in a comfortable scattered place in a light penumbra it is enhanced. At the same time, signs of loss of needles or partial loss of decorativeness due to lighting, if we are not talking about direct sun or strong shade, usually do not appear in cypress trees.

Compensating for low light in winter is a very important point in a plant care program. Cypress trees need to be moved to a more lighted place so that the level of illumination for them remains the same. When grown indoors, it is best to place plants as close to windows as possible in winter.

Plants can be placed within the penumbra in any room, moving them from the windowsills into the interior. Cypress trees are one of the best plants for decorating northern rooms, where they thrive on windowsills. In rooms with windows of a different orientation, it is worth choosing places at some distance from the window in order to create a lighting mode similar to the northern rooms.

When choosing a place for a cypress tree, you should think about ventilation. Plants feel better near a loggia or balcony, where the windows are often and regularly opened, providing fresh air.

Temperature regime and ventilation

Wintering is a key factor in growing any indoor conifer. But unlike many relatives, cypress trees can retain their decorative effect even if they are not kept in the cold. For them, temperatures from 12 to 15 degrees are considered sufficient for successful wintering.

This conifer is not afraid of lower temperatures, hibernating quite well at 5-10 degrees of heat. But an excess of 16 degrees is unacceptable for a long period. The warmer temperature can only be partially compensated for by increasing air humidity.

During the period of active growth, from spring to mid-autumn, cypress trees will feel better, the cooler the temperatures in which they are kept. Stable readings from 18 to 23 degrees Celsius are ideal. It is better to limit the maximum indicators to 25 degrees, at any excess, immediately taking measures to increase air humidity and access to fresh air.

The love of fresh air in cypress trees is so strongly expressed that without ventilation, the plants will not be able to grow even in the cold in winter. Any opportunity to take plants out into the fresh air, place them on a balcony or in a garden, even for a few hours, should be used. Such air baths will only benefit indoor cypress trees.

In the warm season, when at night the temperature does not drop below 15 degrees of heat, these conifers prefer to spend outside the premises. When taking out into the open air, it is worth remembering the need to gradually train the plants and mitigate the difference in conditions.

But the main secret of preserving the decorativeness of cypress trees when moving to fresh air and back is the correct choice of lighting. In the garden or on the balcony, cypress trees are placed in the shade, even a light partial shade will be too bright for them.

Cypress care at home

Not only the health of plants depends on the quality of care, but also how many years cypress trees will be able to delight their owners. Cypress trees do not like extremes, preferring constancy. They grow superbly with moderate watering and require very special feeding. And if bonsai are grown, then you also have to take care of their regular formation.

Watering and air humidity

Gorgeous cypress trees do not like irregular watering. Any miscalculations with watering result in a significant loss of decorative effect, and if problems with moisture become regular, then the plant most often dies.

Cypress trees do not tolerate either complete drying out of the soil or stagnant water. Even in summer, plants are watered to maintain light, constant moisture. The frequency of the procedures should be selected, allowing the upper third of the potting substrate to dry out.

Different types of indicators cope with the task of constant humidity control. Even if it is possible to establish a certain frequency of watering (the standard is 2 times a week in summer), it is still worth checking the condition of the soil regularly.

For a dormant period, watering for cypress trees is somewhat changed. At this time, any waterlogging is very dangerous. The soil should only remain moist, the plants are rarely watered, with a small amount of water, maintaining vitality, but greatly reducing the moisture content of the soil compared to the summer period.

Indoor cypress trees should always be watered with a small amount of water, avoiding waterlogging of the soil and dividing this procedure into several passes for uniform and high-quality moisture. When watering needs to be increased, they are not made more abundant, but only pauses between waterings are shortened.

Water for irrigation should be soft. Cypress loves melt water; when kept in the heat, they use the spreading of snow or ice crumbs around the plant.

To maintain the attractiveness of the crown, cypress trees need an average or slightly increased air humidity - from 50 to 70%. In rooms, even with frequent airing, only this measure will allow the plant to maintain the decorative effect of the needles.

For cypress trees, you can install the simplest humidifiers in the form of bowls and pallets with wet stones or pebbles, or you can limit yourself to spraying. The smaller the spray tip, the better. It is better to avoid getting too wet, as well as the accumulation of water droplets in the needles, but a light wet fog refreshes the plant and stimulates its development.

Spraying can be carried out not only in summer, they can compensate for high temperatures, but in no case should spraying be carried out when the air temperature is below 18 degrees Celsius.

Top dressing and composition of fertilizers

This conifer is very sensitive to excess fertilizers and does not tolerate excessive fertilizing or their wrong composition. Cypress trees react painfully to both lack and excess of trace elements. It is worth feeding for this indoor conifer only during the period of active growth, in spring and summer.

Top dressing per year after transplantation can be carried out once a month or, as a standard, 2 times a month, but the dosage should be halved for monthly procedures and 4 times for standard procedures. In the years when the transplant is not carried out, fertilizers are applied in a standard amount during procedures 1 time per month and a halved dose of 1 time per 2 weeks.

For feeding indoor cypress, it is better to choose special fertilizers - for conifers. If a suitable formulation is not available, you can also use bonsai fertilizers (including bush plants).

Trimming and shaping a cypress

These procedures are carried out only for bonsai and for sanitary cleaning. The rules for the formation of bonsai are standard; plants should be cut and guided 2 times - in spring and autumn. Formation should be started as early as possible, both roots and shoots are pruned. Shortening of long shoots and pinching is acceptable to maintain a compact shape.

Transplant, containers and substrate

Cypress trees do not tolerate transplantation very well. They require extreme care when carrying out this procedure, preserving the whole earthy coma. Any contact with the roots is undesirable.

Transhipment of plants is carried out infrequently, when the roots are almost close to the walls and the cypress trees are sufficiently developed. It is not worth waiting for the appearance of roots in the drainage holes, focusing primarily on the growth of the crown. The optimal frequency of transplantation for young plants is once every 2 years, for adults it is better to carry out these procedures altogether less often.

In years when transplanting is not carried out, it is imperative to remove the contaminated soil layer from above, without contacting the roots, and adding fresh substrate.

For indoor cypress trees, it is worth choosing a rough, permeable and nutritious substrate. Acidity is very important: cypress trees grow only in acidic soils and, unlike other indoor conifers, do not adapt well even to neutral ones. It is best to look for special soil mixtures for conifers, but they are suitable for cypress trees and soil mixtures for rhododendrons.

Self-formulated mixes are undesirable (except for access to quality, controlled ingredients that mix turf, sand and leafy soil in a 4: 1: 2 ratio).

Cypress trees do not like it when the roots completely fill the substrate, they need deep enough, but not too large pots. For ordinary bush and tree forms, containers are selected according to the size of the root system, for bonsai - the deepest of the bowls, providing enough space for free root growth.

The height of the containers should slightly exceed the width, while with each transplant, the diameter is increased by 3-4 cm. Cypress trees are very demanding on materials. They thrive in breathable containers - wood, unglazed ceramics, terracotta, stone and concrete containers.

A high drainage layer is laid at the bottom of the tanks. When planting indoor cypress trees, it is very important to maintain the same level of deepening of the root collar: it should not sink into the soil and should be located just above the upper starting line.

After transplanting, the plants are kept in the shade with high air humidity, reduced watering and several treatments with solutions of rooting stimulants. Top dressing begins only after 1 month.

Loosening the soil for cypress

If there are signs of soil compaction, it is worthwhile for cypress trees to lightly loosen or aerate, but you need to act very carefully, using special tools for indoor plants. Regular loosening procedures will keep soil breathability and texture constant.

Diseases, pests and problems in the cultivation of cypress

Yellowing of the needles, drying out of the plant are the most common symptoms of problems in the development of cypress trees in the room. They do not tolerate dry air, direct sun, high temperatures, or drying of the substrate. But insufficient feeding with an exhausted substrate can lead to the same symptoms. A careful analysis of conditions and care with immediate measures to change them is the only remedy.

Indoor cypress trees are rarely affected by pests or diseases. Aphids and spider mites are found only on neglected bushes.

Cypress propagation

For indoor cultivation, it is better to grow cypress trees from seeds, although rooting of semi-lignified cuttings, albeit with a low percentage of rooting, is also quite suitable.

Cuttings from cypress trees are taken from the apical or lateral parts of the shoots. The cut is carried out on twigs, which are just beginning to lignify at the base, exactly 1-2 cm under the "strip" of transition into green tissue or by tearing off small branches entirely with the heel.

The cuttings are treated with growth stimulants, you can root them in the ground or in a greenhouse under a hood, or it is possible with lower heating in ordinary mini-greenhouses. In garden cypress trees, layers can be rooted for separation into indoor culture.

Sowing seeds is carried out after stratification for 4–5 months and treatment with growth stimulants in shallow containers. They can only germinate with very light and constant soil moisture and bottom heating in bright light. Young plants require careful maintenance.
