Yellow leaves - what to do?
Yellowing of leaves is itselfa common problem in orchids. And first, let's look at the causes of this trouble. Yellowing of the leaf is due to insufficient nutrition. That is, to him practically do not receive the necessary substances for normal growth. There are several reasons for this. First, it can be a natural process - some types of orchids dump old leaves in the dry season. Secondly, the cause of the disease can be fungal infections, which in turn arise because of an excess of moisture. Very often we buy an already infected plant and wonder why it disappears with time. After all, the orchid looked quite healthy in the store. The answer is simple: it means - it was not properly taken care of and too much watered. At the first signs of infection, it is necessary to immediately start treatment. The sooner you do this, the faster the plant will get its original look. The main thing to remember is that the treatment will be needed not only for the leaves, but for the roots of the plant. It is from them that the whole flower becomes infected. If you just delete the missing piece of paper - this will not help. Over time, the plant will lose the second, third ... And it will be impossible to revive it. So, we begin to act. First of all, it is necessary to dry the flower well. All - and the roots, and the stem. This will slow the growth of infection. Remove the flower from the pot and leave it for a day in a dry place. Get an antifungal drug (fungicide) and process the orchid, following the instructions in the instructions. Once the roots are completely dry, place the flower in a new soil and try to closely monitor the moisture. Do not fill the plant! In order to avoid the above problem, follow some tips:
- Orchid loves well-lit places, so make sure that there is enough sunlight;
- Never put the plant in a pot. Otherwise there will be a stagnation of water, then diseases can not be avoided;
- Do not allow the pot of the orchid to stand in the water. After watering, check the pan and, if necessary, drain the water from it.
How to heal the roots of an orchid?
First, I want to give a little advice: When buying, always pay attention to the roots of the plant. It will not be difficult to do, because orchids are usually sold in transparent pots. If all the roots are dark brown, flabby in appearance - do not get a flower! Most likely, he is already infected - such roots can not be cured. The flower is doomed to destruction. Healthy roots - dense, have a greenish or silver hue. If you can not avoid root problems, do the following:
- Spread a piece of polyethylene or newspaper on the table;
- Carefully remove the flower from the pot. It is not difficult to do this: take it by the stem and start rocking, holding the pot with the other hand;
- After pulling out the plant, shake off the roots well from the ground;
- Find the infected areas: in these places the roots will be sluggish, when pressed from them, liquid may pour out;
- Carefully remove the missing roots by cutting them with scissors up to the living tissue;
- Treat the plant with an antifungal agent;
- Take a new pot, previously disinfected with soap and fresh soil (buy ready in the store);
- Pour a layer of soil on the bottom of the pot, place the roots of the plant on top;
- Holding the plant with one hand, the second fill the gaps between the horses' soil.
It should be remembered - an orchid does not like too muchfrequent transplants. Experts recommend that this procedure should be conducted no more than once in two years. If any problems with the health of the flower is not observed, you can transplant the plant and every three years.

Then it is necessary to spray with the same phytoverm;
Live in the ground. And the purchased land can be contaminated by them. If the time is not taken, all the plants in the house will suffer from this parasite.
