The peas may not attach readily to smooth, vertical dowels. I suggest running a couple of strings horizontally from dowel to dowel the length of the row. Peas will grab this sort of thing with little or no help.

I agree, I have a half a dozen in a large pot and I had hoped that they would clib off of the three thin bamboo bits I put in for them but they need constant vigilance in order for me to run them up, I went out of town for two weeks and they all fell over, I'll head out soon and wrap some string in and make it a bit like a cage.

Goodluck.
