Studying the rules of transplanting, choosing a pot, substrate, watering will help you figure out how to properly care for the Dendrobium orchid.


Transplantation of Dendrobium orchids is carried out every 3 years, provided:

  • compaction or decomposition of the substrate;
  • the container is filled with roots;
  • acidification or salinization of the substrate from irrigation;
  • rotting of the roots;
  • after buying the orchid is transplanted.

It is worth replanting the plants to transplant This is because the roots of the orchids are fragile.

Pot for transplanting

For transplanting, opaque pots are selected. It will be possible to transplant the orchid subject to the following rules:

  • the orchid is aged in succinic acid solution for 10-15 minutes (the tablet is dissolved in 1 liter of warm water);
  • the roots are filled with moisture and change greenish-milk color;
  • after they are dried for 30 minutes and placed on a substrate in a pot;
  • pseudobulbs are placed closer to the edge;
  • the root remains on top neck;
  • if the roots are evenly spaced, the gaps are covered with bark.

If the orchid leaves become soft and like a rag, they are cut and treated with fungicide, and watering is stopped until the soil dries to 2/3 of the capacity.


Cracks begin to appear in the following cases:

  • if the plant fell, the leaf is bent, mechanical damage begins to appear;
  • excess full-time amount of nitrogen – to save the roots taken out of the substrate, you need new land for transplantation, are fed with potash and phosphorus fertilizers for 3 months, restoration will last a year;
  • temperature difference, hypothermia after watering;
  • Irregularities in watering lead to leaf damage.

  • lack of lighting;
  • overheating;
  • erroneous watering;

  • in the half-filled pot is placed by the baby;
  • the substrate is added and compacted;
  • the growth point remains on top.

Propagation by seeds

Propagation by seeds has its own characteristics. Seeds are sown on a nutrient medium in special flasks, grown under laboratory conditions.

Division of the bush

How to divide the bush:

  • pseudobulbs are separated from parent plant;
  • cuts are made into cuttings with 2-3 knots, 10 cm long;
  • planting is carried out on a moist sphagnum, in an area closed in a zip bag or in a greenhouse.

  3. Gray rot is manifested by small watery spots on the flowers and buds, provoked by a fungus of the genus Botryties.
  4. Cercospore infection occurs from a yellow spot on the leaf below , after spreading to its upper part. Spots cover the entire leaf, as a result, it falls off the plant.
  5. Botritis – gray spots appear on the leaves and pseudobulbs. The disease occurs due to increased humidity, poor ventilation, excess nitrogen, and poor lighting. The diseased orchid is removed from the plants and treated with fungicide.

Bacterial rot

Bacterial rot is treated with copper-based fungicide, copper sulfate is suitable for treatments . Parts with damage are cut off and removed, the remaining parts must be treated with fungicide 2-3 times with a frequency of 10 days.

Pseudomonase will be treated by destroying bacteria and eliminating their localization in the environment, where they can be preserved and infect the plant. The infection on the leaves is treated with hydrogen peroxide.

The surfaces must be treated with chlorine, it is important to treat plants in the neighborhood, as the disease develops quickly.
