While indoor Chamaecyparis (False Cypress) vies for the title of “most indoor” conifer, flower growers have turned their attention to the more compact, hardy, and versatile Chamaecyparis. even as a winter hardy plant in the garden, it is willing to move into a room, no less than the “dream plant” we can’t control Chamaecyparis. and they adapt more easily to indoor conditions. It would be a big mistake to call Chamaecyparis easy to grow – they are a species for experienced and meticulous growers. But they are amazingly imposing, useful, and colorful. You will learn how to grow and care for Chamaecyparis in the ThumbGarden article.


HOUSEPLANTS – CHAMAECYPARIS

Very similar in appearance to Cupressus, Chamaecyparis is a hardy alternative and the only substitute for subtropical and tropical Chamaecyparis in countries with harsh winters. Although there is no barrier to the low hardiness of indoor cultivation, it is not the true Chamaecyparis that is increasingly appearing on the shelves, but the more diverse, less expensive, and more popular garden Chamaecyparis.

Chamaecyparis is an ancient member of the Chamaecyparis family. They are widely distributed throughout the Northern Hemisphere. Plants that traditionally represent indoor culture are also used in local landscaping.

Although all Chamaecyparis are quite large plants in nature, indoor Chamaecyparis remain compact, medium-sized evergreen species. Usually only young, immature Chamaecyparis with soft needles are planted.
Because of its slow growth – 1-2 inches (2-5 cm) per year – Chamaecyparis is placed in indoor forms for up to 10 years. One to two-year-old cuttings and young seedlings that have begun to form a canopy is preferred. The younger the plant, the better it will adapt to indoor growth.

The shoots of Chamaecyparis are thin, densely branched, flexible, and often bent at the ends, becoming thicker and stronger over time. The brownish-red bark is very beautiful, but you can barely see it under the needles.

The conifers of Chamaecyparis, especially when young, surprised with their softness. Tender, pleasant to the touch, and not at all stiff, the dense needle-like arrangement of young Chamaecyparis has a rich color palette. Even the simplest, non-variegated plants have bluish needles.

The true “adult” flattened, scaly needles of Chamaecyparis appear after a few years, and on older plants, the needles are even denser. As it ages, the color deepens, the upper side of the needles becomes darker, and white spots can be seen on the underside.

All indoor Chamaecyparis plants can be considered effective fungicides and the best plants for purifying the air, without exception. They not only fight against toxins but also inhibit pathogenic bacteria and effectively disinfect the air.

One of the most popular reasons for growing Chamaecyparis as a houseplant is to replace Christmas trees. Chamaecyparis is beautiful and neat, fragrant and gorgeous, and looks great as a replacement for spruce. However, since the warm overwintering period is not suitable for them, you should not bring them indoors for decoration and use for more than 5-7 days.

Chamaecyparis that have become ornamental, wilted, elongated, or overgrown can be planted in the garden and tried to be preserved, observing the rules for garden species. Overwinter with air-dried mulch for the first 2 years.


CHAMAECYPARIS OR CUPRESSUS?

Confusion when buying indoor conifers is unavoidable. Even juniper and bristlecone cypress are sometimes suggested as Chamaecyparis, not to mention confusing Chamaecyparis with Cupressus because they are similar not only in name.

Some plants are treated as other plants, and for many, Chamaecyparis or Cupressus are almost synonymous. Still, the type of conifer to be purchased is quite important. It determines how the canopy varies with age, temperature, and even humidity requirements.

Chamaecyparis is generally not as whimsical as Cupressus and can very easily lose its ornamental qualities and start to dry out if there is a slight deviation from the ideal environment. So if you’re looking for a sturdier, fast-growing, compact version – check the Latin name and choose Chamaecyparis over Cupressus.

You can usually guess the species from the price: Chamaecyparis is more affordable and common when young, and because the plant is more popular and easier to propagate, saplings cost less.


TYPES AND SPECIES OF INDOOR CHAMAECYPARIS

In its indoor form, Chamaecyparis cannot boast a diversity of species: only a few species are suitable for this form of cultivation.
Most indoor Chamaecyparis are pea-like Chamaecyparis pisifera. they are represented by ornamental forms and varieties with a conical but sloppily forked dense crown at the top or spreading shrubs. Its dense, soft needles and wide range of colors are its main strengths.

Increasingly common are the ornamental forms and varieties of Chamaecyparis lawsoniana, especially the “Elwoodii” series, which are particularly compact. These are slow-growing, cone-shaped conifers with flexible shoots and striking canopy colors – blue, gold, white-green.

Indoor Chamaecyparis can be divided into two types of plants

  1. the usual shrubs and trees.
  2. Bonsai.

Growing conditions and care of miniature replicas of natural giants do not differ from unformed miniature versions, only pruning is somewhat more complicated.

For everything from lighting to watering, all Chamaecyparis have the same requirements.


GROWTH CONDITIONS OF INDOOR CHAMAECYPARIS

All indoor conifers are considered to be similar. However, each species has its own “twist”. Chamaecyparis prefers fresh air and, when potted, requires a specific light regime. However, it is generally easier to find a suitable location for them than for their competitors.

Lighting and placement

Many indoor conifers need only bright light, but Chamaecyparis is a pleasant exception. Even in the living room, it retains partial shade tolerance, but varieties with original coloration prefer light to the pure green Chamaecyparis.

Direct sunlight can be very dangerous for them, even if only for a few hours in the evening or early morning. The degree of the shade should be chosen individually. Depending on humidity and aeration levels, the same plant in different rooms can be both more light-dependent and more shade tolerant.

In finding the right light regime, it is best to be guided primarily by the color of the needles. In shady locations, Chamaecyparis will lose its color intensity, but is comfortable, diffuse light-shade locations – it will increase. However, Chamaecyparis does not usually show signs of needle loss or partial loss of ornamental quality due to light, except in direct sun or intense shade.

Compensating for the lack of light in winter is a -very important point in plant care. Chamaecyparis should be moved to a brighter location where its light level remains constant. If grown indoors, it is best to place the plants as close to a window as possible during the winter.

These plants can be placed in the penumbra of any room by moving them from the window sill. Chamaecyparis is one of the best plants for decorating northern rooms and they will do well on a window sill. In rooms with windows in other directions, you should choose a spot away from the window to create a lighting regime similar to that of a northern room.

When choosing a location for Chamaecyparis, it is worth considering ventilation. Plants feel better near a log cabin or balcony, where windows are often opened regularly to provide fresh air.


Temperature control and ventilation

Overwintering is a key factor in growing any indoor conifers. But unlike many of their relatives, Chamaecyparis can remain ornamental if not kept in cold conditions. 50-59 °F (10-15°C) temperatures are considered sufficient for successful overwintering.

This conifer is not afraid of cold temperatures and can overwinter fairly well at 41-50 °F (5-10°C). But temperatures of 59 °F (15°C) are unacceptable for a long time. The warm temperatures can only be partially compensated by increasing air humidity.

During the active growth period from spring to mid-autumn, Chamaecyparis will feel better at lower temperatures. stable values of 68-77 °F (20-25 °C) are ideal. Maximum temperatures are best limited to 77 °F (25°C), and if exceeded, take immediate steps to increase humidity and exposure to fresh air.

Chamaecyparis plants love fresh air so intensely that they cannot grow without ventilation, even in the cold winter months. Any opportunity to bring the plants into the fresh air by placing them on the balcony or in the garden, even if only for a few hours, is worth taking advantage of. Indoor Chamaecyparis plants will only benefit from this air bath.

In the warmer months, when nighttime temperatures do not fall below 59 °F (15°C), these conifers prefer to spend their time outdoors. When bringing them outdoors, it is worth remembering to gradually accustom the plants and moderate the change in conditions.

But the main secret to keeping Chamaecyparis ornamental in the fresh air to and from is the correct choice of lighting. In the garden or on the terrace, Chamaecyparis are placed in the shade; even light-colored shade is too bright for them.

The quality of care determines not only the health of the plant but also how many years Chamaecyparis will keep its owners happy. Chamaecyparis do not like extremes, preferring consistency. They grow well with moderate watering and require very specific fertilization. And if you grow bonsai, you should also be careful to shape them regularly.

Watering and air humidity

The magnificent Chamaecyparis does not like to be watered irregularly. Any misjudgment of the watering can lead to considerable loss of ornamental interest, and if moisture problems become a regular problem, the plant will most likely die.

Chamaecyparis does not tolerate either complete dryness of the soil or standing water. Even in summer, plants should be watered in such a way as to maintain a slightly constant moisture level. The frequency of watering should be adjusted by allowing the first third of the substrate in the pot to dry out.

Various types of humidity indicators are very good for the task of constant humidity control. Even if you manage to set a certain watering frequency (the standard is twice a week in summer), it is still worth checking the soil condition regularly.

Watering Chamaecyparis is done slightly differently during the stationary period. At this time of year, any overwatering is very dangerous. The soil can only be kept moist and the plants are watered infrequently, with only a small amount of water to remain viable, but with much lower soil moisture compared to summer.

When watering indoor Chamaecyparis, it is best to use small amounts of water, avoid overwatering the soil, and divide the watering routine into several stages to ensure even high-quality watering. When it is necessary to increase watering, do not make it richer, but simply shorten the pause between waterings.

Watering water should be soft. Chamaecyparis prefers melting water, uses snow or ice chips around plants when kept in high temperatures.

Chamaecyparis needs moderate or slightly increased air humidity – 50 to 70% to keep its canopy attractive. In a room, even with frequent aeration, only this measure will allow the plant to maintain its ornamental needles.

For Chamaecyparis, you can install a simple humidifier in the form of a pot and a tray of wet stones or pebbles, or you can limit yourself to spraying. The finer the nozzle, the better. It is best to avoid getting too wet and to prevent water droplets from accumulating in the needles, but a gentle moist mist will refresh the plant and stimulate its development.

Spraying can be done in the summer to compensate for high temperatures, but never when the air temperature is below 68 °F (20 °C).


Fertilizer and fertilizer ingredients

This conifer is very sensitive to over-fertilization and will not tolerate over-fertilization or the wrong fertilizer composition. Chamaecyparis is sensitive to both too little and too many nutrients. You should only fertilize this indoor conifer in the spring and summer.

Fertilization for the year after transplanting can be done once a month or the standard 2 times a month, but the monthly treatment should be halved to the standard treatment of 4 times a month. In years when transplanting is not performed, fertilization is applied once a month with the standard dose, halved every 2 weeks.

For indoor Chamaecyparis fertilization, it is best to choose a fertilizer specific for conifers. If suitable compounds are not available, bonsai fertilizers (including shrub fertilizers) can also be used.


Pruning and shaping Chamaecyparis

These procedures are carried out only on bonsai for hygienic cleaning. The rules for shaping bonsai are standard; plants should be pruned and directed 2 times – in spring and in autumn. Pruning should be started as early as possible, both roots and shoots should be pruned. Shortening long branches and pinching is acceptable in order to maintain a compact shape.


Transplanting, containers, and substrates

Silk Chamaecyparis do not handle transplanting well. They need special care to keep the root ball intact during this process. Any contact with the roots is undesirable.

Transplanting should be done irregularly when the roots of the plant are almost close to the wall and Chamaecyparis is fully developed. Do not wait for the roots to emerge in the drainage holes; focus primarily on crown growth. The best transplanting frequency for young plants is once every two years; for older plants, less frequent transplanting is preferable.

In years when transplanting is not done, be sure to remove contaminated soil layers from the top to avoid contact with the roots and replenish them with fresh substrate.

A coarse, permeable, and nutritious substrate should be chosen for indoor Chamaecyparis. Acidity is very important: Chamaecyparis grows only in acidic soils and, unlike other indoor conifers, is not well adapted even in neutral soils. It is best to look for a conifer-specific soil mix, but a rhododendron mix will also work.

Homemade mixtures are not advisable (unless a good quality composition with controlled characteristics is available, allowing you to mix turf soil, sand, and leaf soil in a 4:1:2 ratio).

Chamaecyparis do not like their roots to completely fill the substrate; they need pots that are deep enough, but not too large. For common shrubs and woody forms, containers should be chosen according to the size of the root system; for bonsai, the deepest pots should be chosen to give the roots enough room to grow freely.

The height of the container should be slightly greater than the width, and the diameter should be increased by 2 inches (5 cm) per transplant. Chamaecyparis are very picky about their materials. They grow well in breathing containers made of wood, unglazed ceramic, terracotta, stone, and concrete.

A high drainage layer is placed at the bottom of the container. When growing indoor Chamaecyparis, it is very important to keep the root neck at the same level: it should not sink into the soil and the position should be just above the upper starting line.

After transplanting, place the plant in a cool place, keep the humidity high, reduce watering and treat it several times with a rooting agent solution. 1 month will pass before it starts to fertilize.


Loosening the soil for Chamaecyparis

If there are signs of soil compaction, a light loosening or aeration is worthwhile for Chamaecyparis but should be done with extreme caution, using special tools for houseplants. Regular loosening procedures will help to maintain the permeability and texture of the soil at all times.


Pests, diseases, and problems in the growth of Chamaecyparis

Yellowing needles and plant shrinkage are the most common symptoms of problems with Chamaecyparis in the room. They cannot tolerate dry air, direct sunlight, excessive temperatures, or dry substrates. But insufficient nutrition and depleted substrates can lead to the same symptoms. Careful analysis of conditions and care and immediate action to change them – the only remedy.

Indoor Chamaecyparis is rarely affected by pests and diseases. Only aphids and spider mites occur on neglected shrubs.


PROPAGATION OF CHAMAECYPARIS PLANTS

For indoor cultivation, Chamaecyparis is best grown from seed, although half-tree cuttings are quite suitable for rooting, despite the low rooting rate.

Cuttings of Chamaecyparis are taken from the apical or lateral part of the shoot. The cutting is made from the branch that is just beginning to lignify at the bottom, just below the “stripe” transition to about 1 inch (2.5 cm) of green tissue, or by tearing off the entire branchlet with the heel.

Cuttings are treated with a growth stimulant and can be rooted in the ground or under mulch in a greenhouse or in the low heat of a regular mini-greenhouse. Horticultural Chamaecyparis can be rooted by transplanting to separate into chamber cultures.

Seeds are stratified for 4-5 months and treated with growth promoters in light-colored containers before sowing. They can only germinate if the soil is very light, consistently moist, and in bright light with low heat. Young plants need careful care.
