I was checking our local weather forecast this evening on Weather Underground when a google ad popped up for garden trellis. I followed the link and found this.
I can't get the link to work so just go to www.gardeners.com and do a site search for trellis. The page will come up.
Those are some neat looking trellis for a lot of different applications and they seem to be reasonably priced. I've always built my own trellis and I know I can't buy the wood and wire to build one for what these cost plus these look like they can be folded and stored or easily moved at the end of a season.
