How to Fertilize Orchids – Secrets, and Tips

In this article, we will explain how to fertilize orchids correctly. Most people believe that fertilizer is some kind of miracle product with the ability to save and revive the worst orchid we can find. The reality is different. If the orchid is in a very bad condition, compost or fertilizer will not be the solution. Fertilizer is an aid for an orchid in good condition, which will give it a plus of vitality and health.

Why Do Orchids Need Fertilizer?

When an orchid leaves its natural habitat, we are taking away the orchid fertilizer it collects from nature. Substrates such as spruce bark, moss, cork, gravel, or other products with which orchids are grown commercially, lack many essential nutrients for these plants.

Because of this, regular fertilization is desirable and necessary to provide the essential nutrients needed by the orchid to maintain good health and bloom.

Which Orchid Fertilizer to Use?

In the stores, we can find an infinity of fertilizers for our orchids. If you are looking for orchid fertilizer, choosing one can be a difficult task. You will probably hear a lot of opinions about fertilizers.

Fortunately, choosing a good orchid fertilizer is not as complicated as it may seem. You will indeed find many manufacturers, but the important thing is to pay attention to the indications of each one of them.

Here are some tips for choosing a good fertilizer for orchids:

  1. Look carefully at the package directions, and choose a fertilizer that contains nitrate nitrogen. Recent research has shown that it is a good product to fertilize your orchid. On the other hand, a fertilizer containing urea is not the most suitable.
  2. Look for a fertilizer containing at most 20% nitrogen. Higher amounts can be counterproductive. If you give your orchid too many nutrients, this can have a negative effect.
  3. The amount of phosphorus does not determine whether the fertilizer is better or worse. There was a time when it was thought that a very high level of phosphorus was advisable. But over time it has been shown that the level of phosphorus does not matter so much to fertilize correctly.
  4. In many situations, a calcium and magnesium fertilizer can be a plus to help the orchid grow and bloom properly.

By following the requirements we have indicated, you will be able to fertilize your orchid correctly. However, you have to keep in mind that you have to make the mixture correctly. You will find this on the label of the fertilizer container for each type or genus of orchid.

Important Note: Do not use processed tap water to fertilize your orchids. It is always best to use rainwater or distilled water.
