I use a pair of shears, which I did today, which knackers my arms, but is quiet, quick, convenient, and I don't end up loosing the tops off any of my plants that are a touch close to the path. Ava has a great big loud boys toy petrol jobee, which periodically, throughout the course of the year, he wields alarmingly around the plot, masacre-ing anything that is taller than 3 inches! My lottie neighbour has a very cute little rechargeable strimmer and it lasts just long enough to whip around his plot, keeps it neat, and it is so quiet!
