I just use a 1/4" steel bar for mine. I use these rubber ties that you can cut to whatever size length you need, to attach the vines to the steel bar. I don't even bother with using moss to wrap the metal stake. The monstera's aerial roots don't even bother trying to attach themselves to it anyways. The potted roots have completely filled in the entire pot, so all I did was shove the metal stake down the center and the mass of tangled roots do a great job of keeping the metal stake upright and not letting it move around.

Hi Christy,

I'm an in the process of creating a support for my Monsteria and I used PVC pipes. It is almost finished, it just needs a few finishing touches. I apologize in advance for the picture quality and the lack of drawing skills.

I used two PVC pipes, one 2 inch and one 6 inch. I thought that 6 inch would give enough girth so I had the option to train the vines in a circular motion around the pipe but 6 inches would take too much room in the pot. To avoid this, I used a two inch pipe from the bottom of the pot and attached the 6 inch at soil level. I used brackets at the bottom of the 2 inch pipe that I attached to the bottom of the pot. I have included a quick drawing that may explain it better. I forgot to draw the screws that attach the two pipe! There is two, one at the bottom and one at the top. The screws go though both pipes.

I should also mention I have holes in the pipes to let moisture out and then wrapped the pipe in coco moss sheets. I then in between the two pipes, I filled it with vermiculite. So I can water in the pipe to help with moisture. I should point out that I used caps at the bottom of each pipe and drilled holes in them to fit the pipes and sealed with a glue gun, so that the vermiculite would not pour out the bottom.

Anyway what I like about my design, is I can add a PVC connector and increase the height, once the plant gets taller. I have also noticed that the air roots are starting to attach to the coco moss :)

Oh I forgot to mention, that while this is my design, I had a very handy man, with lots of tools helping me :)

You explained yourself very well, and that's a great idea! I also have a very handy man at my disposal, I'm definitely going to show him this. Thank you!
