I wouldn't worry too much about the flowers dropping off, it may just be that the plant was coming to the end of it's flowering season. I think if you get the cultivation requirements correct you should not have too many problems with pests etc.
Cytisus (Broom) need full sun, if you want to continue growing it in a pot make sure you use a soil based compost e.g. John Innes no2. and if possible grow it in a shltered spot away from strong winds. Check how hardy the cultivar is and move it indoors in the winter if necessary.Statistics: Posted by gardening_guru — 18 Aug 2011 12:58
