"K-Lite" Fertilizer

[raybark]

In the March issue of the AOS Orchids magazine, there will be an article by Rick Lockwood entitled "What do Orchids Eat?". It includes some interesting revelations about the long-term negative effects of excessive potassium in the diet of epiphytes.

In the Fall of 2011, a bunch of us (including Rick, as he originated the concept) began experimenting, using a low-K fertilizer derived for us by Dr. Bill Argo, the "MSU Fertilizer" guy. To-date, there are almost 100 folks from all over the US, Canada, and several other countries around the globe using it, and it is proving to be an excellent orchid food. I won't go into details here - read the article when it comes out - but we are the sole retail source of the formula, available at our online store.
