It's no secret that very often you can find orchids at a flower shop at a markdown. This means (not always, but often) that the plant has spent more than a month in the flower shop in the most difficult conditions of overflow, hypothermia and lack of sunlight. The result is an almost complete absence of roots.
So I could not resist, and bought a cymbidium at a markdown. The plant became very sorry. When I pulled it out of the pot, it was like this.
The roots below were healthy.
But the top turned out to be rotten.
The roots of cymbidiums are very fragile and break easily, rot forms in the places of the floors, so if the root is broken, it must be cut off at the place of break and wiped with alcohol or sprinkled with coal.
Rotten roots should be trimmed back to healthy tissue at the root. Healthy roots are yellow, firm, hard, rotten - hollow, black, soft.
For transplanting, I took a translucent bucket (or a pot for orchids) and made holes there for better air access.
Either it can be planted in clean bark or with the addition of moss and peat.
After buying the cymbidiums, it is necessary to transplant, since very often insects and snails are present in the ground, the roots are often rotten, and the substrate is too moisture-consuming.
Since the cymbidium is a terrestrial orchid, it also needs light earth for terrestrial orchids. I bought at OBI.
To get to the middle and remove the rot, I had to divide the plant (very carefully).
Here are two neat little bushes that turned out in the end. It is necessary to let the wounds dry for about 10 minutes, and if the roots were damp - several hours.
After that, it is imperative to pour a sufficient layer of drainage into the bottom. And place the delenki with directed new growths in the middle of the pot, so that the plant has room to develop before the next transplant.
After that, it is necessary to cover it with a substrate so that the bulbs are on the surface. Do not water for the first 4 days.
Here is the end result. If you are not sure that you can water properly, make holes not only in the bottom, but also in the sides of the pot.
