An orchid is a plant with colorful and long-lasting flower clusters. So many people love to grow this plant in the home and garden. However, orchids also require more care than some other plants in your garden.

In particular, one of the issues that many gardeners care about is fertilizer for orchids. Each type of plant needs different nutrition and ratio and so does the orchid.

What Is Fertilizer For Orchids?

Specific fertilizer for orchids is a completely wrong and misleading concept for gardeners. Most manufacturers often label some fertilizers such as orchid fertilizer or fertilizer for roses….to sell at a higher price in the market.

However, most fertilizers contain ingredients such as ammonium nitrate, potassium nitrate, potassium phosphate, ammonium phosphate, calcium nitrate, magnesium sulfate, and cobalt sulfate. These are all the same chemical ingredients in fertilizers to provide nutrients for plants in general and orchids in particular.
