Any experience in using sea kelp additives on orchids?
Has anyone here tried to use kelp extract on orchids? It's classified as a "plant stimulant" or "plant growth regulator". It's not the same as regular fertilizers. Through a project my company worked on in Alaska to map kelp resources for harvesting, I know it is used commercially by apple and other fruit growers to, for example, help all the fruit ripen at the same time to lower the costs of harvesting. In other plants it supposedly maximizes bloom size and aids root development. I still have some concentrated product from that project which used to be marketed as "Garden GROG", and would like to try it on some of my orchids. But thought I'd throw this out first for advice. (The marketed kelp additive is not just ground up kelp with lots of deadly salt in it - it took over a year of "fermentation" before it was packaged for sale)....
