Orchid Fertilizer

In general, orchids don't require a lot of fertilizer. In nature, as orchids grow suspended from trees by grabbing their bark with their roots, orchids only get what food their is in the decaying organic matter in the nook of a tree branch or that washes down the tree as it rains. Yet, as we cultivate orchids in our homes they do require a modest amount of fertilizer.

Orchids do not thrive on standard plant fertilizers because the nitrogen source in those fertilizers is primarily urea which orchids cannot absorb very well. Similarly, the type of Potassium in many fertilizers is not optimal for orchids. There was a study done at Michigan State University (MSU) on fertilizer for orchids which was published in both Orchids magazine and the Journal of the International Phalaenopsis Alliance in 2003. This study, and the resulting orchid fertilizer formulation is known as "MSU Orchid Fertilizer". This fertilizer formulation is known as the 'gold standard' fir orchid fertilzer.
