Organic Fertilizers on Mounted/Bare-Root Orchids

[Roberta]

Hard to say what the long term benefits are... mine get a low (half teaspoon/gal of MSU) spritzing about every 2 weeks, a shot of Kelpak once a month or 6 weeks. So basically hardly anything. And they do just fine. People tend to focus on fertilizer because that's easy to control and measure. The rest of the environment is tougher, but far more important.
