Why do leaves turn yellow from the orchid ?

Orchids - the largest family of monocots.It is also one of the oldest in the world, there was presumably Late Cretaceous.These flowers primarily known as a very beautiful ornamental plants, which are more likely to be seen in the greenhouses.The most popular types: Phalaenopsis, Dendrobium and Cattleya.

Currently, orchids are common on all continents except Antarctica.Most species grow in tropical latitudes, as these plants like quite a lot of rainfall.In the temperate latitudes of the flowers look much poorer, also here, there are far fewer of their species (up to 900).In Russia and the former Soviet Union found a little more than 400 species.

It is worth noting that many orchids are currently under strong pressure of human.Those Phalaenopsis, are very popular, including in our country, are on the verge of extinction (or rather, some of their species).This is due to the fact that in the places of their growth continued destruction of tropical forests in order to turn them into farmland.Also, the

problem lies in the fact that the collection of these plants to meet the global market demand is too great.But even worse is that the way the planet has already lost several orchid species, which are known to us only through the descriptions from old books.Not so long ago, it was adopted rules governing the trade in flowers, but experts claim that this does not help, because the main problem lies in the destruction of the natural environment of flowers grown.

Causes yellowing leaves

Oddly enough, but the problem, which we will begin to discuss with you right now, is facing a huge number of growers, and very experienced.Even in these plants the leaves shrivel and become yellowish.Let's find out whether it is possible to rid the plant of the disease and, if so, how?

  • Very often it happens that the leaves begin to turn yellow from the ground up, and after a while simply fall off.What is the cause of this phenomenon?Experts believe that it is likely in low-light conditions.In addition, do not ignore the problem, since not only the dry leaf and its base, but also part of the stem, which can lead to other difficulties with orchid.all remnants of damaged leaves, and if beneath the stem not the usual green color, and black or brown, it is desirable to cut the entire top of the plant should be cut.Only in this manner can stop the spread of damage to other tissues of the plant.Yes, it's hard to decide on, but the other way exit.However, it all depends on the specific situatsii.Stoit noted that the restoration of the plant after such a "surgical" intervention on your part will depend entirely on how much healthy tissue is left in the flower.Remember, the more you will have the top of the length, the faster orchid restored.
  • Another cause yellowing leaves - the natural life cycle.Not everyone knows that the orchid develops like any other plant, so drop-leaf - the process is quite natural.They can fall away at different times: some - in a year, while others - in three, and the last - after five years.
  • What else?Another is to pay attention to the availability of fertilizers.It is possible that your flower is simply not enough potassium - that happens often, because potassium tends to be redistributed from the old to the new tissue, so start with the leaves of the problem.Solve this dressing with a high content of potassium.
  • Often, a similar problem arises in the lack of iron.However, in this case, the solution may be a few others - transplanting the plant in fresh substrate, as well as iron-dressing fertilizer.
  • And pay attention to the air - if it is too dry, you may need to install a humidifier that will be useful not only orchids, but also your health
