Potted Christmas tree, bought last year. Miraculously survived all year, so was feeling virtuous about not having to buy another this year. It looks lovely- all bushy and green. Got it inside yesterday, decked it up with lights baubles and tinsel, and it SMELLS FOUL! Think it must have been used as a toilet by neighbour's dogs. Can't leave the windows open- it's too cold. Am contemplating spraying with tea tree oil and lavender, but not sure if that would damage the foliage. Any dog owners out there have any solutions?
