This year I have grown a number of flowers from seed and some of these, including the marigolds, have ended up in a large tub containing an ornamental pear tree, . They always add a great splash of colour but are often prone to slug attack. So to fend off the hungry slime balls , a ring of copper was fastened to the tub. It appears to have worked as I now have a great floral centre-piece to the garden. Here are a few pictures of these golden plants.
