I have no chance... if I started at one end and did a total tidy up then by the time I got to the other end the first bit would be overgrown again. During summer it's a battle of compromise with mower and strimmer and then come autumn a major tidy-up and prune out: a couple or three tractor waggon-loads by the time one has pruned and cut down all the pondside growth and gone round the trees....
