Orchid - today the most popular plant for lovers of indoor floriculture. And this is understandable, because her flowers combine both tenderness and proud splendor.
If you notice the first signs of the disease, thenthe main thing is to determine why the leaf turns yellow at the orchid. One of the reasons is insufficient lighting. In this case, the sheet begins to turn yellow at the very base and subsequently disappears. I must say that such damage is dangerous for the plant. After all, the base of the leaf dries and part of the stem under it. It is necessary to cut the entire damaged leaf and examine the stem itself. It should be green. If it is brown or black, then all the same it is necessary to cut off the whole top of the plant. Only this will stop the damage to the rest of the flower of the flower. Restoring it will depend on the amount of healthy tissue left. The more it remains, the faster the orchid will recover.
Fungal disease is another reason why the leaf turns yellow in an orchid. This is due to improper irrigation, or rather, due to stagnation of water in the roots of the plant.
If the leaves turn yellow at phalaenopsis orchids, then,perhaps its roots are "clogged" in the pots. It will be enough to remove the pots, replace the substrate and plant the plant in a plastic pot with large holes on the bottom. It is desirable that the pot was transparent, then it is very clearly visible, in what condition are the roots of the orchid.
At home, most often grownphalaenopsis orchid. Why the leaves turn yellow, and how to avoid it, is probably already understandable. Do not allow water to reach the base of the sheet. These orchids are watered by immersion in water. Do this enough once a week. From time to time, change the substrate. And do not forget that the plant should be in a bright room, but not under the direct rays of the sun.
