Feng Shui supports the cultivation of orchids at home, based on it, the plants are female flowers . It is easy to grow dendrobium at home under special conditions and requirements.
Dendrobium is heat-loving, in winter the temperature is 15-20 ° C during the day, 6-12 ° C at night. .
In summer, for the dendrobium orchid, the temperature in the daytime is 18-25 ° C, at night 14–20 ° C.
The temperature during dormancy in winter at night is 15-18 ° C, in the daytime 20-25 ° C.
The east and west sides of the house will fit, darkening will be required on the south window.
In spring and summer, water well during growth, the soil should be moist. In winter, watering the orchid is required less often, the dry content is observed.
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.
Water the Dendrobium after 3-14 days, it depends on the size of the roots and wound healing from damage received during transplantation.
Substrate for dendrobium
Caring for Dendrobium involves the selection of substrate during planting. The main components are:
- medium sized pine bark;
- crushed polystyrene;
- broken brick.
Before use, the substrate is disinfected, spilled with boiling water and dried.
Consequences of improper care
Cause of occurrence The problem is improper care, they will need resuscitation.
Damage to the root system occurs due to improper care:
- excess moisture in the substrate;
- overfeeding with fertilizers;
- caked substrate;
- lack of watering;
- overheating of the plant.
If the orchid is in the pot tightly, the roots are fine, if they are brown in color, hollow, slimy, it is worth tackling the problem. The flower is pulled out of the pot, roots with damage or decay should be trimmed. Then they are sprayed with a solution of phytosporin, the ground part is also subject to processing. Orchid should be planted in a new soil after the moisture has dried.
The trunk rots
The trunk begins to rot from bottom to top. This happens due to the development of root rot. If signs of the disease are detected, phytosporin treatment and transplantation into a new soil are used.
Due to improper care of the orchid, Dendrobium leaves wither and turn yellow, they become lethargic and fall off. The main reasons:
- attack by spider mites;
- the leaves begin to rot due to waterlogging;
- tissues atrophy when there is a lack of moisture;
- root damage often occurs.
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.
Leaves turn yellow
Causes of yellowing:
- flower ages;
- is affected by diseases and pests;
- a chemical burn of fertilizers or growth stimulants appeared on the stem or other parts of the plant;
- stresses: relocation, lack of lighting, humidity, poor air temperature, irrigation errors.
If the leaves of the plant turn yellow, steps are taken to lay it down education and rehabilitation.
Loss of buds and flowers
Reasons for dropping buds:
- habitat change;
- lack of lighting;
- erroneous watering;
Orchid planting should not be next to the fruit, they emit ethylene, affecting the aging of flowers and buds.
Sticky drops can appear on leaves, bulbs and young shoots. The reasons for their occurrence: the attraction of insects, protection against external factors, excess fertilizer, irrigation errors and the presence of pests.
Dendrobium is propagated by children, cuttings and with division of the bush.
Reproduction by children
A baby is a small process with buds of roots.
Separate and put the baby out:
- if the baby has grown to 5 cm, she is cut;
- the roots are nourished with moisture;
- in the half-filled pot is placed by the baby;
- the substrate is added and compacted;
- the growth point remains on top.
The seedling is fixed with a support, the conditions of the greenhouse are not are needed. It is required to spray the top layer of the substrate between irrigations. Closer to autumn, children with roots grow on stems, they should be separated and planted in new pots.
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.
The temperature is maintained at a level of 20-25 ° C, ventilation and watering of the planted are required. After 2-3 weeks, the plant takes root on the cuttings, then they should be planted in pots with a substrate.
Cutting at home
Cuttings are a method of propagation of the dendrobium, while pruning the apical part of the shoot is done or the shoot is divided into parts 10-12 cm long. The cuttings are aged in a root solution for 24 hours, then root in a sterile container, water is added to the bottom of the container. After a few months, the plants will have a developed root system, they are ready for planting.
Reproduction of Dendrobium by cuttings at home is a simple way. It will not be quick to root the cuttings, the process will take about six months, this is the negative side of the propagation method.
Another way to reproduce the plant is to cut the flowering stems of the plant into ground level. After they are laid horizontally on wet sand and kept moist for several months.
Proper care of orchids is of great importance for them, thanks to him the plants
For the treatment of fungal infections, the plant is treated with fungicide Ridomil Gold.
There are infections:
- Phyllosticosis – yellow spots appear, darken, leaves dry and rot.
- Fusarium spotting harms leaves, pseudobulbs, flowers, buds. The causative agent of the disease penetrates into the orchid through damaged leaves, roots. Dendrobium is not completely cured; it is isolated from flowers, sheared and disinfected. In spring or summer, the flower is transplanted into a new soil and pot.
- Gray rot is manifested by small watery spots on the flowers and buds, provoked by a fungus of the genus Botryties.
- 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.
- 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 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.
Bacterial decay appears as brown spots, less often watery with a yellowish color. The plant will be revived by spraying it and around it with a fungicide before and after wet weather. After identifying the disease, the infected area is excised and treated with a fugicide.
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.
Viral diseases develop slowly and cannot be treated. They appear in the form of spots, the leaves deteriorate gradually and die off. There is no way to save the plant, therefore, other plants throw it away and save it, the room is subject to wet cleaning with disinfection.
Pests are dangerous:
- spider mite;
They harm the foliage and flowers of the orchid, the plant dies. Upon detection, it is necessary to begin treatment of the plant.
Insecticides will help to combat pests: Fitoverm, Biotlin, Vermitek, Aktara, Sanmayt and others. The humidity around the plant is also regulated, the leaves are washed every 2 weeks with soap and water.
To prevent and protect orchids from pests, ventilate the premises and prevent drafts.
Dendrobium orchid is distinguished by a variety of species and the ability to propagate it at home. With proper care, you can grow a beautiful plant.
