Transplantation is one of the main points in the cultivation of Dendrobium orchids. The substrate, which is still quite attractive, over time, loses properties such as breathability, normal acidity, balance salts. The soil is compacted from frequent watering and fertilizer: to the roots of the plant receives less and less air. In addition, from watering with tap water ph rises gradually. As a result, the plant ceases to absorb from the environment the necessary elements. The roots often suffer from the accumulation of potassium and phosphorus salts.
Considering all the above, Dendrobium re-pot every 2-3 years, and in some cases even more often. If we are talking about the newly purchased plant, transplant it immediately after flowering or in the first year from the date of purchase. High probability that the flower is purchased in the substrate from birth.
Spring time is the best for the transplant of Dendrobium. Beginning a period of new growth of the plant. In the course of which often appear new shoots and roots. Before you pull the Orchid from the pot, a little remember its walls with his hands. The substrate will be better to give in. Of course, provided that the walls of the pot is made of plastic. Now try to pull the flower. If attempts do not lead to success, no matter how beautiful the pot, break it or cut it. If the root system of plants developed very strongly, to get the substrate really difficult. Because the roots are intertwined. Weakened Dendrobium extract from the pot is much simpler: simply pull it up.
Now remove the bark from rhizomes of Dendrobium. To do this, pour into a basin of warm water, and put the Orchid in 15-20 minutes (maximum an hour). When the substrate is melted, try to stir and untangle the roots with your fingers. This should be done in the water. The risk of damage is minimized. The dirty water in the basin change in time. If necessary, use a shower with little pressure. The stream of water should wash substrate from roots, but not to damage them. Do not try to clean off all the bark: pieces that are firmly ingrained in the roots, you can leave.
After washing again carefully examine the root system: remove all rotten and dry. Also remove the damaged areas: healthy root tissue is white or green. Note that the normal root system is solid and durable to the touch, and the patient has voids. To plant has not penetrated the bacterial or fungal infection, cutting items be sure to disinfect with alcohol or calcined over a fire. Place slices sprinkle with charcoal, activated charcoal or cinnamon.
Now dry the roots of Dendrobium within two hours. The room temperature at this time should be warm. A very good option is to wash the roots of the plants in the evening and leave overnight to dry. In the morning you can proceed directly to transplant. If you are preparing a substrate alone, before transplanting it to disinfect: boil on the fire for 3-4 minutes or pour boiling water for 10 minutes. After that, the water drain, and the substrate dry. Especially this procedure is recommended if the mixture emits a smell of forest mushroom. However, the easiest way is to buy ready - made substrate in the store. Now pick the right pot for a Dendrobium. Focus on the size of the root system: lower roots in the pot, the sides should remain 2 cm free space. This option is the best. On the bottom of the pot, place a layer of drainage pebbles, expanded clay, foam.
Correctly place the Dendrobium in a pot: it needs to be in the center. After you pour the roots of the plant substrate, but pseudobulb leave on the surface. For stability stick to the substrate, wooden sticks and bind them to the plant. As soon as Dendrobium tightly strengthened, it will have new roots, shoring can be removed. When transplanting in the dry substrate pour the flower in the process of this procedure. So, the soil gets compacted naturally. If you dried roots of Dendrobium not more than 2 hours, then pour it only in 2-4 days after transplantation. Provide for transplanted plants a comfortable environment: medium lighting and humidity. The temperature should be 20-22 °C.
Never obesity cuts or wounds of plants are brilliant green, iodine, alcohol. Contained in these liquids of a substance rises by capillary action up and dry up the healthy tissue.
Don't put just transplanted Dendrobium at the bright sun. Under the action of the rays of the plant was very hot and receive heavy stress.
