From past experience I can tell you that the trunk will start to rot away and turn into pulp. If you were to put annual vines I think it would be alright, but for heavier vines or things that don't die I don't think I would use the trunk. At my old house I had hubby cut the stumps to about 4-5 feet and used them as places to put my pots...that is until they started rotting and my pots started sinking.

Thank you for the information.

I hadn't considered that the palm would rot, but that makes sense. Guess I'll have to come up with a new plan. My husband isn't wild about planting vines near the wood fence so that is out.

they rot really fast. I used cut up pieces of a palm as a border - and I knew it was temporary. I had no idea how temporary. Rotted in a single summer.

So much for recycling. LOL
