Pole for vertical gardening Use it with a Topsy
Turvy upside down planter if you don't have someplace else
to hang it. Works great on balconeys, porches, etc. You can
hang four of those Topsy Turvy bags from it, so you can have
a whole garden in just a few feet of space. As long as you
have some sun, you're golden!

Garden
Arbor Garden arbors come in wood, vinyl, and
all types of metal. They are great for climbing vines, flowers,
etc. This site has a good
selection of garden arbors.

Even if you don't have room for a full sized arbor, there's
always room for a garden
trellis!
