I use coco liners for my orchids. I also buy them at Lowes or Home Depot. I add some sphagnum moss along the base of the liners. With dirt plants, maybe some potting soil mixed with something that retains water. I haven't had mine break down in 2 years and they are growing in the hot Florida sun. I have noticed the baskets which are not planted, have started shredding and I'm assuming it was caused by the heat and drying out. Not sure, but I would add something that holds some water at the base of the basket.

Mine seem to hold up pretty good except right around the top edge and they are starting to look pretty ragged. I will definitely add the moss next year though. Great Idea, thank you.
