Hi loll. Although a novice I always do hanging baskets and tubs/ it does depend on the plants you put in. I like to use ivy leafed geraniums (don't know proper name) which have reached a 30in drop. also trailing fu*hsias, trailing lobelia,geraniums, busy lizzies. In fact almost anything I have and fancy at the time. I am eagerly awaiting time to hang out... they are really getting quite good at the moment. I am fed up with hitting my head on them when I go in the greenhouse. Happy gardening Lorna.
