Sometimes I will get a call that starts with, "its a bit of a jungle" or maybe "I've let it get out of hand" this can mean anything from the grass hasn't been cut for a few weeks to nothing has been done for five years and there are tigers living in the shrubbery.
This particular customer had let things go a bit, lots of over grown shrubs weeds in the border, but mostly the grass needed cutting.
I went over all the grass with a strimmer first, then raked up the cuttings, before running the mower over twice. After that it looked surprisingly like lawn.
This was over a year ago, since then I have been going back every couple of weeks and have started to sort out the trees and shrubs as well as keeping the grass under control.
