The herbaceous perennial plant Rhoicissus, also called birch, is a member of the Vine family and is characterized by rapid growth. Its stems can be creeping or rambling, and in natural conditions their length can reach up to 300 cm or even more. This perennial is native to tropical South and Central Africa.
The birch tree is cultivated as an ampel plant at home. It is characterized by its rapid growth.
If left uncut, it can grow to a length of about 150 cm. Quite large leaf plates have a bright green color. The shape of the leaves directly depends on the variety and can be very different, for example: rounded, palmate, grape, etc.
Flowering of such an ampelic plant is observed only in nature, while it is not of particular decorative value. In summer, short peduncles are formed from the leaf axils, on the tops of which a large number of very small pale green flowers are formed, which are gathered in umbrellas.
Brief description of cultivation
- Temperature. During the growing season, about 21 degrees. The plant should overwinter in cooler temperatures - about 15 degrees, but it should not be colder than 10 degrees in the room.
- Humidity of the air. It should be moderate.
Roicissus grows also in low humidity, but only with regular moistening from a sprayer.
- Lightness. Can be grown in shade, but the plant feels best when given plenty of bright, diffused light. Don't forget to shade the shrub from direct sunlight at midday.
Moisten the substrate moderately after the top layer of the soil mixture has dried: in the warm season - once every 3-4 days, and in the winter - 2 or 3 times a month.
- Substrate. You can take a ready-made store substrate, which must be fertile and friable. You can make the soil mixture yourself by combining sod, garden and leaf soil with perlite (sand) in a 2:2:2:1 ratio.
During the growing season once every 15 days with a liquid mineral complex for indoor crops.
- Transplanting. It is carried out when the bush becomes cramped in the pot. Young specimens - 1 or 2 times a year, adults - once a year, and in old ones - transplanting is replaced by annual replacement of the top layer of soil mixture with fresh substrate.
By shoot parts, bush division and cuttings.
- Trimming. Systematic pruning of the upper parts of the stems will make the bush thicker and tidier.
- Care features. The plant should be regularly given a warm shower to wash the dust off the leaves.
In summer, if desired, the shrub can be moved to fresh air (balcony or garden), shading it from direct sunlight at midday.

Home care for Roicissus
In the spring and summer, the bush should be kept warm at 18 to 22 degrees. It should be moved to a cool place to overwinter, with an air temperature of about 15 degrees, but no colder than 10 degrees.
Roicissus grows and develops quite normally in low humidity.
But to keep the leaf tips from drying out and the plates themselves from turning bright green, the shrub should be moistened systematically from a sprayer. This should be done twice a week with well-distilled, non-cold water.
The plant develops and grows normally in slight shade or in bright, diffuse light. It does not need long days of light. A window facing east, west or south is best for the shrub, but should be shaded from the midday sun.
Water abundantly during the growing season, but only moisten the substrate when its top layer has dried to a depth of 10-20mm. For irrigation suitable settling water, the temperature of which should be close to room temperature. In the cold season resort to reducing the frequency of watering, but make sure that the lump of soil in the pot does not dry out. Otherwise, the leaves may fly off.
To plant roicissus, use a roomy and stable pot.
Since it is a fast-growing crop, you will need to replace the container at least once a year with a larger one. Once you have planted the shrub in a pot measuring 30 centimeters across, you can stop replanting, but remember to change the top layer of potting soil with fresh substrate once a year.
Birchberry is undemanding of substrate. It grows very well in any store-bought ready-mixed soil, which must be definitely friable and nutritious. If you want the substrate can be made your own hands.
To do this, mix 2 parts garden, leaf and turf soil each, and add 1 part sand (perlite).
As this plant is a fast-growing plant, it actively draws nutrients from the substrate. Because of this, the shrub needs obligatory systematic fertilizing, which is done with a frequency of 2 times a month. To do this, use a mineral complex for house plants in liquid form. And this ampelous culture also responds well to organic fertilizers.
Because young bushes grow most actively, they should be transplanted at least 1 or 2 times during the year. Mature plants need to be replanted each year, with the old pot being replaced by a new, larger one.
Older Roicissus bushes are extremely difficult to replant because they are very large. You should therefore only change the upper 30mm layer of potting soil to new potting soil once a year.
As the years go by, this indoor plant may become overgrown, resulting in a loss of its decorative appearance.
To avoid this, remember to systematically prune the tops of elongated stems. You should also cut off any shoots which you think are spoiling the appearance of the Roicissus. The cut-off shoots can be used as cuttings if you wish.
Roicissus flowering in indoor conditions is a very rare occurrence. Under natural conditions, the plant usually blooms in early summer.
From the leaf axils appear unattractive small pale green flowers which are part of umbrella-like inflorescences and have short petioles.
This plant needs an obligatory dormant period in winter time. With the onset of the cold season, when the daylight hours become very short, the plant is moved to a cooler room (about 15 degrees). Moisturize the substrate at this time should be moderate and infrequent, otherwise the root system can become rotten. During the winter, the flower is not fed.
Growing from seed
The seed material of Roicissus germinates very poorly. Because of this, this method is rarely used by florists for propagation.
The top parts of the shoots are used to make cuttings. Each one should have 1 live bud and another two or three fully formed leaf plates. In prepared cuttings, the cutting places should be sprinkled with charcoal powder.
For rooting, cuttings are planted in any soil mixture, as long as it is friable. Instead, they can be put in a glass filled with water.
Rooting Roicissus cuttings is quite simple and fast. After the formation of several strong roots the cuttings are potted in a permanent pot of its own.

Raubbing with Stem Parts
Raubbing of Roicissus with Stem Parts is very similar to cuttings.
However, the prepared sections are placed horizontally on the surface of the soil mixture. Above the container must be covered with glass or film. After about 4 weeks young shoots should appear from the leaf axils. When the plants have grown and become stronger, they can be transplanted into permanent pots.
A mature bush can be split into several parts during transplanting.
Each part should have roots and shoots with leaves. Treat the cutting points with charcoal powder and then plant the dividers in separate pots.
The houseplant Roicissus is undemanding in its care and keeping conditions, and is also resistant to disease. However, the following problems can occur if care is not taken properly:
- Brown spots on the foliage. These are burns left by the scorching rays of the sun.
Remember that the shrub needs protection from the sun's rays during the midday hours.
- Furrowing of the leaves and pulling of the stems. The bush is standing in an excessively dark place. Choose a more suitable and lighter place for it.
- Yellowing of the leaf plates.
This can be because the plant feels an acute lack of nutrients. And this problem also occurs with improper watering. Roicissus must be fed regularly and must not forget to water in a timely manner.
- Drying out of the tips of the leaves. The air in the room is very dry.
Provide the bush with timely moistening of the leaves from a sprayer.
- Pests. Most often on such a room culture settle powdery worms, whiteflies, spider mites and aphids. To get rid of the pests, the plant is treated with an insecticide solution.
