| Should have added this...I'm not sure how much rainfall you get and/or how many orchids you need to water but...you could consider collecting rain water and using it whenever possible.
I've heard mixed emotions on this topic but I've been doing it for years for my tropical houseplants....long before I was growing orchids. When I started growing orchids...naturally, they got the same treatment and everyone seems to be real happy after a good drink of rain water. |
