Look at my post below this one and see what I used.Do you have a way of using one of those kinds of shelves in your greenhouse??

Beautiful display, Kathi, and thanks for the suggestion. It is always more fun to use something like your shelf that has some character!

thanks,

Karen

Chris uses chains, and that seems to work pretty well. He has a lot of Eriostemmas, which aren't nearly as woody as kerrii, but still tend to grow very up and straight, so it's a similar scenario.

Here's one link, I know there are more threads where he posted pictures, but I can't find them atm. Anyway, I like that method.
