One of the most picturesque and colorful Oriental shrubs in indoor culture – Nandina Domestica. This is a single plant with very spectacular leaves and curly crown, the beauty of which can not take your eyes. A unique charm of the foliage acquires in the cold season when its colors change as if by the whim of the artist-watercolorist.
Even the love of coolness does not prevent this plant from becoming more and more popular. It rightly ranked among the elite species of houseplants. This capricious miracle is not for everyone, and it loves attention and care.
Nandina domestica and its spectacular change of colors
Among houseplants have Nandina just no competition. In the ranks of evergreen crops spectacular watercolor colors with such carved foliage – a rarity. Unique, luxurious, capricious, rare, exclusive – how her is not called, all the epithets are justified. Here, and in the West, is very fond of calling sacred bamboo. Also, it is a beautiful name that captures a unique beauty in every sense of luxury of a Bush.
However, it also causes much confusion: neither the characteristic features nor the origin of the plant to bamboo have nothing to do and got this nickname presumably for the tendency to release the root shoots, for their thin stems and a similar form of a variegated leaf. This charming shrub in nature is found only in Japan and China. Belongs Nandina domestica of the Barberry family.
Nandina domestica – evergreen shrubs
Rarely – dense trees, even in nature limited to a maximum height of 4-5 m, and in indoor culture rarely grow to one meter (on sale mainly dwarf varieties). It is distinguished by its virtually non-branching, straight, thin shoots and compact, surface root system. Crown air, graphic, stunningly elegant. However, this does not prevent the plant from actively releasing many root shoots. Even nandina’s bark is very picturesque.
Changing color from lilac-beige to grayish-brown, flaunting longitudinal grooves, it conquers with its muted matte. Sacred bamboo is grown in the form of potted shrubs with thick foliage of the picturesque or in the way of bonsai.
The plant from afar is perceived as a small-leaved culture, but the share of feathery leaves in length grow to 10 cm elegance emphasizes the long petiole of leaves (up to 15 cm) and reaching 3 cm in length petioles feathery lobes that give the crown airiness.
The color scheme of the foliage
Watercolor show in plants is fully manifested in the cold season, but some “preview” can be seen all year round. Young leaves with their muted red, brick-brown tone gradually change color to dark green, as if red with time slowly eroded base color. Despite the status of an evergreen plant, nandina varies colors depending on the season.
Autumn begins the watercolor show, during which the leaves are gradually and unevenly repainted in dazzling red and ruby tones, and transitional shades look extremely attractive. In winter, it looks like a bright crimson miracle slowly and unevenly begins to boil and turn yellow. However, the change to brown does not indicate that soon the plant will lose its leaves:
- the closer to spring,
- the stronger the green color appears,
- and the sheets are repainted,
- then against their background glittered reddish young leaves.
So luxurious-colorful Sacred bamboo there are numerous varieties with bright, intensely red, purple, multicolor color.
However, the miracle of the colored crown is not the only talent of the plant with the right winter and blooms. Begins Lacy flowering in June and lasts only a few weeks. Small flowers fantastic original: white sepals rejected ago, highlighting the massive six stamens around the pistol.
Despite the small size, the flowers are gorgeous.
However, even more, surprising is the size of the inflorescences: unusual flowers are collected in long and translucent openwork panicles of inflorescences, the length of which can exceed 30 cm. After flowering, tied large dazzling berries, gradually acquiring scarlet-ruby color. Fruits with a pointed tip up to 1 cm in diameter on this plant look like luxurious beads.
The conditions of the growing
The beauty of this plant is unmatched. However, good it deserves the title of an exclusive sissy. Nandina – is not for everyone:
- it is ultra-demanding to humidity,
- consistently intense lighting and temperatures,
- even in the warm season.
Moreover, it can be recommended only to experienced gardeners who are looking for an exclusive decoration of their collection. The demands to the conditions do not change regardless of the form of cultivation, and it is typical for Bush, and bonsai.
Lighting and placement
It needs to choose the place very carefully. Direct sunlight, except for the soft morning and evening, this beauty is contraindicated, the lighting should be bright, but scattered. In autumn and winter necessarily more light for maintaining normal plant modes of maintenance and on artificial lighting responding well.
The flower feels excellent on the Western and Eastern window sills, at the showcase Windows and glass walls, and bright halls will suit her. However, nandina feels best in winter gardens with controlled conditions.
Temperature conditions and ventilation
Regardless of the time of year and stage of development, the flower remains a fan of coolness. Of course, in summer it does not contain unusual room conditions, but the temperature to rise above 20 degrees to allow not worth it. At temperatures from 18 to 20 degrees, the plant retains a high decorative and always only pleases.
During the winter, is moved to more comfortable rooms. Comfortable for this plant is the temperature from 7 to 13 degrees Celsius, allowed short-term cooling.
It loves the fresh air, frequent airing and will happily spend the summer in the garden in sheltered places. From drafts is better to protect. Nandina can be grown as a garden tub.
Care From Nandina domestica at home
It needs care and constant attention. Periodic inspections of the plants, verification of conditions and status of the leaves and substrate, moisture characteristics will allow avoiding mistakes and time to correct the program of care.
Irrigation and humidity
The correct schedule of watering is easy to choose. The plant is watered so that between the procedures the upper layer of the substrate dries in containers. Summer watering should be abundant, but not frequent. In winter, they are reduced, focusing on how the soil dries. Complete drying of the earthen coma should not be allowed.
The initial condition under which you can grow in living rooms and even in winter gardens – high humidity. At the same time, it is not necessary to use individual devices: a pallet or a second container filled with wet decorative stones, moss or expanded clay is enough. Do not allow water to contact the bottom of the pot with the plant and stagnant water at the bottom of the containers.
Installation of the humidifier in the spring and summer is better to Supplement regular spraying. When the content of the fresh spraying is carried out carefully, only soft, distilled or purified, warm water and fine spray can be used for the plant.
Fertilizing and fertilizer composition
Nandina domestica is fed with standard frequency. Fertilizers for this plant are made only from March to September. The optimal rate is one time in 2 weeks. In the autumn-winter period fed and shrub, and nandina domestica bonsai, guided by the instructions received when buying or reducing the dosage and frequency of fertilizers twice.
It is desirable to select a compound, universal fertilizer. This culture prefers liquid fertilizing and does not like long-acting fertilizers.
Pruning and shaping
This houseplant, except for growing in the form of bonsai, is not needed. The lack of thick branching, thin, straight and graceful shoots will not thicken the crown and pinching, and with targeted pruning. The release of a large number of young shoots stimulate shortening by a third of the oldest branches, and their cutting with a frequency of 1 every 3-4 years control the size and rejuvenate the Bush.
The formation of bonsai is most often reduced to exposing the lower part of the shoots, limiting the size of the plant by removing the shoots and part of the trunks. Nandina easier to buy already formed, rather than give it style and form of then.
The only necessary measure is the regular removal of old drying leaves, which the plant does not always drop from the bottom.
Transplant and substrate
To change capacity for plants need only then when fully mastered previous pot. Young Sacred bamboo is transplanted each year, but adults need a transplant one time to 3 or even four years. In years when the operation is not carried out, be sure to replace the top layer of the substrate to fresh.
It was usually grown in large pots with equal aspect ratio, increasing capacity by a few centimeters.
For cultivation select universal, loose and comfortable ground mix. The perfect substrate for decorative-deciduous plants. If you mix the soil yourself, you can use a substrate of equal parts sand, turf and leaf soil. To the reaction of the soil culture undemanding, feels useful in the ground with a pH of 4 to 6.5, but weakly acidic soil for it is still preferable.
Transplantation is carried out without exposing the roots, with minimal contact and removal of the upper layer of the contaminated substrate. At the bottom of the tanks be sure to lay the high drainage layer with a thickness of at least 6 cm for classic pots and about 1/3 the height of the containers for bonsai. The root neck of the plant cannot be buried in the soil. If necessary, you can limit the volume of the root system, cutting it to a more compact size.
Diseases and pests
Sacred bamboo reasonably stable, but if not properly maintained can suffer from spider mites or aphids. It is better to fight pests with insecticides.
Among these plants is widespread mosaic spotting, which is easy to see on the specific yellow spots on the leaves. Most often plants are infected before buying. To deal with this problem better systemic fungicide.
Common problems in growing:
- dropping leaves when the temperature is above 20 degrees;
- partial or total loss of leaves in dry air;
- spots on leaves in contact with sunlight;
- yellowing of leaves when watering with hard water, lack of iron or magnesium;
- pale leaves in low light and in the absence of fertilizing;
- elongation of shoots and the growth of weak twigs in low light.
Slow rooting of cuttings does not mean that you can not grow your plant from twigs. The main thing – to use semi-woody shoots, to withstand cuts in the growth stimulant and planted in a light substrate under the cap. You have rooted cuttings at a temperature of 20 to 25 degrees. Usually, the process takes at least one month.
Nandina seeds – a rarity, despite the abundant fruiting plants in winter gardens. Sowing is desirable to carry out immediately after ripening and harvesting, but although low, germination seeds retain up to 3 years. Seeds are sown to a depth of 1-1.5 cm, in loose and light soil. Under glass, they are also kept in tropical temperatures (23 to 25 degrees) and bright light.
