| Cholla is a good mounting material if you are not growing under wet greenhouse conditions, and is better than most if growing under dry conditions because it does absorb water.
Mount the plant towards the bottom with it growing upwards. with the cholla you might consider placing the sphagnum behind the cholla so that the base of the plant is on "dry" material. When I have a hollow cholla tube I pack it full of coconut chips, charcoal, and sphagnum with good results. I use twist tie wire or zip ties to secure the plant. They holds the plant tighter and can be removed in a year once the roots attach. Fishing line is better for binding a big wad of sphagnum under the plant though. |
