The nutritional program at Michigan State University is vastly different from the majority of recommendations circulating within the horticultural world about the fertilization of orchids. This fertilizer is now being referred to as “Michigan State University’s Magic Fertilizer.” This RO Water Special or 13-3-15, was designed for a pure water source like rainwater or reverse-osmosis (RO) purified water or water that has been treated for city use such as tap water. Due to the extreme variability of well-water mineral content, the RO Water Special formula is the preferred choice for the home grower.
The MSU Fertilizers were designed and formulated for use in the MSU research and teaching greenhouse ranges on a broad range of horticultural crops: Easter lilies, poinsettias, annual bedding flowers, perennials — just about everything but orchids, but the formula proved to be exceptionally good for them.
It is recommended give two to three applications of the fertilizer followed by a generous root drench of water (Fertilize for three weeks, then the 4th week just apply regular water to flush out any salts which may have built up in the pots).
Our packaging is perfect for those with small collections. Each bag contains 100% original Greencare granulated MSU Fertilizer with a measuring scoop included. The package is a metal mylar package with a resealable zipper to ensure no moisture intrusion. Small packages were specifically chosen to allow for cheaper shipping options, to help with storage as well as to reduce any large loss from potential moisture exposure (Those of you who have lost a 5lb bag of fertilizer to moisture intrusion will know just how frustrating this is)
