making pots and mounts

I would like to think they could be, but I'm not sure. I've never done that but plants I grow in clay pots do well and I've used small pieces of broken clay pots as an additive to some of my media. I would definitely use a bit of moss if you do. You could try. Experiments lead to experience. Good luck

 

I have seen terra cotta pots as mounts. They had a Catt growing on the outside of an upside down pot and I have also seen many overgrown orchids attach roots to the outside of the pot they are growing in. I would probably not use broken pots as broken terra cotta can be deceptively sharp.

 

I know this is an older post but interesting, I am also a rockgardner, we use a natural rock called tufa to grow many tiny plants, it is hard to come by and rather expensive. I wonder how small pieces would work as a mount?
We also make troughs out of a mix of portland cement, sand, vermiculite and some fiberglass fibers, it's called hypertufa. This can be formed into what ever shape or size you might want, could you make a pot out of it, or imbed a wire hanger and make a mount?
I wonder how an orchid would do mounted onto it, the rock garden plants seem to do quite well. I do not know if there would be leaching from the cement or if that would be a problem. Anybody have any thoughts on this?

 

I haven't tried that but it appears this artist is doing it with success. http://jamienorth.com/terraforms-2014

 

I think it's best to add a lot of peat moss to the hypertufa before adding the water, in order to lower the pH.

 

Thanks Ray, You are right, I completely forgot to add the peat moss, it is critical to have in there. The recipe is avaliable on the Am. Rock Garden web site. I must have been distracted when I wrote it as I well know that it has to be in the mix to make it stable and lighter. It can be shaped into any form you want as it is the consistancy of clay and very malliable. It does have to cure for a period of time to develope its strength. I have not made any troughs for a long time, they last very well but may try a small batch to try this out. Just don't forget to put holes for draniage in while it is still soft, while still soft the outside of the item can be "sculpted" to any texture you want, look like wood or what ever.

 

I know this is an old post, but I'm able to turn my own pots, bake and (optionally) glaze them.

At the moment I'm attempting to mount plants on the exterior of a pot, which is then watered from the inside. The clay is deff porous enough to keep the pot moist, and I am in control of clay type, shape, bake-type (e.g. low or high fired), which opens a lot of options for experimentation.
Ideas, inspiration, tips, and whatever are always welcome
