Hello Phalspital,
What a clever idea! I also like to reuse things. I have saved my onion bags, I know I can reuse them. You are lucky to still be in So. Fl. I was born and raised in Hialeah, yes Hialeah,
I was blessed to have grown up in the 50's and 60's, so I saw the best of it. Your orchids are beautiful! So is your pool! If you have access to coconuts, open them but....save the outside fiber . Orchids grow so well in them. Just wrap them around the roots. I have a dend. in one. LOVES it. If I could get some up here you bet I would. They will not grow here. Also NO ONE sells whole coconuts.
Thanks for sharing your pics.
