Hi all, I've just realised that for the last few years in those borders which are well established that I've not been doing any planning. When I need to plant something, all I've been doing is digging up and replacing a bunch of Spanish bluebells! If it's a taller plant then bluebells near the rear of a border get replaced, if short then bluebells nearer the front are replaced.
I still have just as many 'planting opportunities' as when I began this regime though!
Anyone else in the same boat?
