Hello all! New to group..been growing (and unfortunately killing) orchids for a couple of years. Finally found the right spot for them I'm in north Florida. I have no green house or room for one. I now have about 10. I just received 6 from a friend who has a plant service in south Florida and they decorate with orchids and then throw them out!😩. We convinced her to give them to us! I would like to mount them to a tree or drift wood. I bought spaghnum moss to help me with this but any ideas or suggestions from you experts?

I'm not the expert in the group but...

I hydrate the wood well, hydrate the moss well. Put a little moss on the wood, spread out the orchid roots and tie the plant in place with dental floss (because I don't have any fishing line). Then its just wait and see.

Next!

Here is a really nice thread regarding mounted Orchids. Perhaps you might find it useful. It contains lots of great pointers and good advice. Just scroll to the beginning of the thread.

If you use driftwood, be sure if it's origin. If it was in saltwater, it will need to be soaked in order to remove salt build up which would kill orchids.

Mount orchids according to light requirements. Do not mount to trees because your area can be exposed regularly to cold winter temperatures. Many won't do well if it goes below 40 on a regular basis. You are better off keeping all mounted plants mobile so you can bring them in if temperatures demand it!
Always mount the orchid with the new lead facing the mount. Never away. When the new roots appear, the plant will take to the mount and establish itself quicker.
Be prepared to water your plants MORE often in warmer weather.

Suitable hosts wood include cypress, live oak, tree fern and cork bark!
