Why do orchid flowers fall off?

We are not going to fool ourselves: the most beautiful thing about orchids are their flowers. For this reason, they are grown and marketed in many parts of the world, and for this reason there are many of us who have ever had a specimen, and / or who currently have one in the bathroom or in the garden for example.

But Why do orchid flowers fall off? Sometimes, we can be convinced that we provide them with all the care they need until one day, for no apparent reason, they run out of them. What to do to make them bloom again? Let’s see it in detail.

What are the causes?

Orchids can stop blooming at any time

There are several possible reasons why orchid flowers drop, and they are as follows:

  • The flowers have reached the end of their life: this is a cause that should not worry us at all. All parts of a plant have their own lifespan, and the flowers are one of those that last the shortest compared to the length of the leaves. In fact, the normal thing is that after one to three months they wither.
  • Very low temperatures or, on the contrary, very high: Orchids are plants that, in general, are native to humid tropical forests, where temperatures remain stable around 18-28ºC. If exposed to values ​​lower or higher than those, the flowers will drop prematurely.
  • Low ambient humidity: as they are plants of humid tropical forests, when they are cultivated in very dry environments they have problems to bloom normally.
  • Excess or lack of irrigation: when more water is added and more frequently than necessary, or if irrigation is neglected instead, the flowers will not be able to receive the amount of water they require.
  • Excess fertilizer or inadequate fertilizer: whether you fertilize more than what is indicated on the packaging or if you use a fertilizer that is not suitable for orchids, they will have a hard time.
  • Inadequate irrigation water: if you use hard water, with a lot of lime, the flowers will fall.
  • They are sick: some fungi, bacteria and / or viruses can affect orchids, such as phytophthora for example, which damages the roots. If they manage to infect the plants, they will abort their flowers.

How to prevent my orchid from dropping the flowers?

Orchids are sensitive to cold

To prevent orchids from dropping their flowers before the end of the season, it is very important to care for them properly.

Thanks to this, you can see when they need water, since you will only have to look at their roots: if they are white, then you will have to water.

Do not forget to use rainwater as clean and pure as possible. If you can’t get it, use the one from the tap but first let it sit overnight so that the heavy metals remain at the bottom.
