Handy tool ...
I may have mentioned this before, but it bears mentioning again -- a battery operated hedge trimmer. Mine is a 16 in. Craftsman and is light enough to hold with one hand to cut off the dead foliage on perenial plants. I just used it to clean up the foliage in a looong planter of asparagus fern and blue plumbago, also for knocking down the dead stuff on shrimp plants.
It will do light trimming on hedges, but for heavy hedge work I haul out the heavier electric hedge trimmers.
I also could not do without the battery operated leaf blower. As well as blowing leaves off the walks and patio I even use it to blow the leaves out of the house that the dogs track in. I have tile floors in the living areas.
Do you have a favorite tool you want to tell us about? I don't want to miss out on anything that saves on yard work.
