The three-tiered metal cages that most people use to support tomatoes also have a place in the flower garden. I use them as inexpensive supports for everything from dahlias to peonies. To adapt them to different-size plants, I cut the three vertical wires to the appropriate height with a hacksaw or wire cutter. The only trick to using the cages is to remember to set them in place before the plants you want to support have grown too large to fit through the rings.
