I have about 15 orchids,, but I have never used Epsom Salts. Most of mine are inside in my double paned bay windows. I have used different fertizers in the past, but recently changed to Dynamite for Orchids, and bromeliads 10-10-17. One of the orchid books I read suggested it. The beauty of it is that it lasts 9 months. I put it in on and forget it. My kind of fertilizer. Sorry, I am of no help. Why do you think it would help the orchids? I am curious. Jennifer

Hi Jennifer, I have about 30 orchids and I have been growing them for 10 years. Some of them stay outside all year round, a few I keep inside. I have read about people who have had good luck using ES on a number of different plants. I was just wondering if a diluted solution could possibly boost my orchids at this time of year, too.
