I often plan for the bigger ones and plant them by a fence so that I can run a twine from the fence in a big loop around the stalks and back to the fence. This helps a great deal. If you have a long bed you can run a section of wire fencing down the middle or just two fence posts near each end and run wire up the middle of the bed. This will allow give you something to tie your twine to. You can use shepherds hooks seated very firmly to attach your fencing to if you do not like the metal fence posts fit with your garden. Then hang something from the hook and feel creative.
