Orchids & African VioletsUpdated a year ago
EM-1 can be used on all plants.
Specifically, for orchids dilute a little less than 1/2 teaspoon (2 ml) EM-1 Garden per quart of water. Apply wkly as a pot drench.
You do need to continue to fertilize the plants with regular fertilizer as EM-1 does not contain nutrients.
