I am planning on growing some Louffa Gourds this year and i am hoping to get some feedback from people that had grown them before.

What's the best way to set them up? A piece of lattice? A pole to climb?

Is the foliage dense enough to use as a temporary screen between me and the neighbors?

I didn't see anything about them being invasive. Can they get away from you and spread out and take over? Or is propagation strickly by seed?

Thanks for all responses and suggestions :)
