Salt build up

[flhiker]

Hi all, I have read that some orchids get a salt build up that will harm the plant. Where does this salt come from? How do you know when it is building up? How do you remove the salt? I water regular with rain water (if they look thristy they get a drink) and fertilize once a month with Rays orchid fertilizer/distilled water. Thanks for the help!

The salts can come from tap water and fertilizers.
Just flush out with plain RO / distilled water or rain water
If your only feeding once per month & using pure water, doesn't sound like your going to have much problem with build up.
