According to this article the recent cold weather has been responsible for a rise in the sales of bird seed. It seems people have been spending a lot of money on our feathered friends this winter. The demand for bird seed has helped the Garden Centre Group post a jump in profits as sales rose 8% in the five weeks up to 27 December. The combination of this and an increased demand for Christmas trees have meant the chain have posted a 17% rise in gross profits to £14m.
