Keeping old bark in pristine condition is a perennial problem, especially in the U.Ks damp climate. Because of the damp weather and regular watering, bark, which is very absorbent tends to be the perfect place for green algae to colonize.
After time this can become quite thick and if not cleaned away will progress to a lush carpet of green moss, under which the precious old bark will be decaying.
Bark Cleaner and Algae Remover solves this problem. The product harnesses the power of sunlight to lift algae away from the supporting surface, it then simply dries up and blows away.
Treatment involves spraying the affected area until it is evenly damp and putting it in the sun to take effect.
