I never cut Geraniums back at this point in the year - I might pull off any long,tatty growths, but I leave the dead foliage on all winter as a bit of protection, then pull it all off as growth begins in Spring. They do benefit from being cut back late July or early August though, after a flush of flowers. Usually you can see new growth in the centre, and when that appears, remove all the older foliage - you'll get more flowers once that new foliage matures.

Brilliant bamboo, thats most helpful, I shall put away the saceteurs, oooo cant spell that!!
