I do feel a bit guilty doing my day-job at people’s gardens, tidying up their patch!
I feel this especially when I need to remove weeds out of their borders. It is not so bad when I have to put other plants in their place or if I have to take out really damaging weeds such as Goosegrass (Galium aparine) or Bindweed (Calystegia spp.) totally swamping ornamental plants.
I always have to apologize to the weed in question, taking it away as it could possibly be a food source of insects and other creatures.
