Mounting anthuriums isn't hard. But depending on your mount, it can be a little crazy. I had to use my ladder to get to where I wanted to put these plants. You may also need strong nylon type or monofilament thread, and/or 14 gauge aluminum wire. If you use natural jute twine, it may rot before the plant attaches well enough to not need support. You also need already wet sphagnum moss.
I decided to mount one of my King anthuriums (Anthurium veitchii) that I had been growing in a little wire basket. The basket was not a galvanized one and I actually never meant to leave it in here this long. But it had started to rust, so it was really easy to get this out without damaging anything.
There were actually 2 plants in this basket so I decided to carefully separate them put them in 2 different locations. The first one I put in the little flat crotch of a tree that I had pruned a branch off a long time ago. The second one I decided to put onto one of my big totems
Basically, you hold the plant's root mass to the mount, place damp moss over it, and wrap it onto the mount with the line or attach it with wire, adding moss as necessary to cover the roots as you go. And this is what you end up with...plants growing like they would in nature. These are small now, but their leaves can get really huge and long. To water, just spray with a hose.
I followed all the same steps to mount this Anthurium pseudospectabile onto a totem. I used 14 gauge wire for this, because this is a huge growing plant that will get heavy. Until it is really attached it needs a stronger support
