I don't see anything 'tender' on your list that can't be just left behind for 72 hours. Water them well, put them on the kitchen counter, and have a nice visit with mom. They don't need water or misting or strong light while you are gone for such a short time.

Same as sensitive tropical fish. Better off to leave them alone for 3 days than have someone do God knows what to them. I would just leave them and enjoy the trip, they'll be fine when you come back.

Don't worry. Orchids won't be hurt if they don't get misted for 3 days (at least the ones you listed). Just move them into a shady area. Enjoy your trip!

Orchid 123 is on the right track with "shady" as the plants won't dry out so much.

Just wanted to follow up on how my chids are and they are better then when I left my paph sanderianum ( prob spelled wrong) now has it's first spike since in my hands bout half in to 3/4 but i darn sure didn't see it when I left. Also my phals have bloomed full force all but one bud do you think me not misting for a couple days and watering motivated the plants to start new growth? Thanks again for all you insight!! I love this forum such great friendly folks

Someone told me that after an orchid finishes blooming I can lay it down on the ground and bury the long main stem after cutting slits at the joints and it will sprout roots like other woody plants do. I was told not to cut it off from the main plant. this is the way I root hydrangers, and gardenias.
Will this work?
