I've changed to the smaller varieties but I still have trouble with supports. I use 4 canes and tie string loosely around as they are meant to be able to have some give unlike tight string. They still tend to snap. I had some cheap garden obelisks and reduced them in height to about 4 feet. This supprted two of them succesfully. I am therefore looking for some decent obelisks again but they are all too high. Any ideas where I might get some and what do others do for staking?
