Of all types of orchids, dendrobium is the most adapted for home cultivation. The owners of a spectacular flower with a delicate scent strive to get as many pieces as possible in order to enrich their collection.
Its reproduction is not difficult; for a successful result, it is required to observe the technology of each of the methods.
Features of the cultivation of this type of plant
Dendrobiums belong to the sympodial species of orchids, and are propagated vegetatively at home. Using some parts of the mother flower as planting material allows you to get new plants.
Unlike other types of orchids, children are very actively formed on the dendrobium. Amateur flower growers most often choose this method.
Methods and their description
There are three methods of vegetative propagation of dendrobium, and all of them have been tested in practice:
- Division of the bush. When the orchid grows strongly, it is divided into equal parts along the rhizome - the main rhizome. New plants take root easily and quickly, flowering occurs in a few weeks.
- Detonation. In the axils of the leaves, dormant buds with airy shoots are formed, which have their own root system. When separated from the main bush, they immediately begin to develop independently. The survival rate in children is high, flower stalks form already a year after planting.
- Cuttings. For this method, pseudobulb stems are used. They are divided into parts and germinated. The process is quite lengthy and sometimes unsuccessful.
If you want to propagate dendrobium, it makes sense to use each method in order to identify the most suitable for a particular variety.
Dividing the old orchid bush is required to rejuvenate the plant. This is usually done once every 4 years.
How to prepare a plant?
- Before starting work, it is worth making sure that the flower is healthy, there are no yellow leaves, and they do not fall off. If only shoots for grafting or children are separated, then no other manipulations are made with the orchid.
- If you intend to divide the bush, the flower is taken out of the pot, the soil is shaken off, the remains are carefully cleaned with hands.
What time to choose?
The beginning of spring is the most optimal time for dendrobium breeding. The orchid enters a phase of active vegetation, the process of consumption of nutrients is intensified. At this point, the plant is easier to tolerate the stress of transplanting, wounds and cuts heal quickly.
Children also successfully take root in March-April. They initially have a small reserve of water and nutrition, which they begin to assimilate immediately after planting. Following rooting, an intensive set of green mass begins.
How to propagate?
Each breeding method has its own technology, the observance of which will be the key to a positive result.
By dividing the bush
Splitting dendrobium into 2 or more specimens is considered an effective breeding method. The main condition is the presence of at least 6 shoots in the plant.
- the orchid is taken out of the pot, the old substrate is removed;
- straighten roots, cut dry;
- determine the places of division so that for each part there are 2 pseudobulbs and the same number of young shoots;
- wounds are sterilized;
- planted in pre-prepared pots, in dry soil;
- the next day, the flowers are watered and provided with normal growing conditions.
The peculiarity of dendrobium as a sympodial species of orchid is that the growth of the bush goes horizontally. As a result, new shoots are formed, and the old ones lose their leaves and reduce the decorative effect of the flower. But it is they who are suitable for the cuttings method.
Stages of work:
- The shoot is separated at the root with a sterile knife from the uterine bush.
- Cut into 10 cm pieces.
- Wounds are treated with coal, cinnamon, hydrogen peroxide.
- Sphagnum moss is placed in a container and moistened.
- Cuttings are laid out on it, covered with a lid or wrapped in a plastic transparent bag and fixed.
- Keep at a temperature of + 20-25 ° C, ventilate once a day.
- If desired, spray it 1-2 times with Epin's solution.
- After 2-3 weeks, roots will begin to appear. Young plants are transplanted into regular pots.
When using the cuttings method, dendrobium blooms for 2-3 years.
If the germinated cuttings are exposed to a low temperature (from +15 ° C and below), then flower stalks will grow from the buds instead of children. Such plants are not suitable as planting material and are thrown away.
This method is considered the most popular and simplest. To stimulate the development of children, do the following:
- reduce watering;
- increase the temperature to +30 ° С;
- humidity is increased to 70%;
- fertilized with fertilizing containing nitrogen.
A pseudobulb will appear from the awakening bud. When 4-5 leaves appear, 2-3 roots and the length of the process reaches 5-8 cm, the children are ready for planting.
- a sharp knife or blade is disinfected with alcohol;
- cut off the pseudobulb under its base;
- the wounds are treated with activated carbon, cinnamon or brilliant green;
- children are left for 1 day to dry;
- prepare a small pot with a substrate of a fine fraction and plant a shoot there.
When planting, the growth point is not deepened.
The first time is watered for 2-4 days. During denrobium rooting, a humidity of 70-80% is maintained, daylight hours are increased to 14 hours a day. The optimum temperature is + 22-25 ° С.
If children do not have roots, then it makes sense to stimulate their education.
- the seedling glass is filled with moss, watered;
- plant a shoot;
- put in a warm, lighted place, periodically sprayed;
- When 3-4 roots are formed, they are planted in a pot using standard technology.
Children should not be immersed in a glass of water. This will lead to rotting of the plant.

Difficulty with a flower after breeding
Since orchids are rather capricious and delicate plants, the reproduction procedure can expose them to stress.
- growth retardation, roots do not develop;
- there is no flowering for a long time;
- yellowing and discoloration of leaves.
To avoid problems, you should make sure that the mother flower is healthy before work. After propagation, young plants are provided with suitable conditions for rapid adaptation and survival.
If flowering occurs in 2-3 years, then this is considered the norm.
Dendrobiums are propagated by vegetative methods: dividing the bush, kidding and grafting. The beginning of spring is the most suitable time for flower cultivation. Compliance with the rules of each method will provide quality planting material.
