If you have wooden fencing in your back garden, you may have noticed that over time, it's susceptible to turning green. This is thanks to a build-up of algae or sometimes moss on the surface of the wood - and whilst it's not necessarily going to cause any damage to the wood immediately, it doesn't look very pleasant.
