Tis the growing season for Lichen at work and buy gum its interesting looking stuff when you get up close to it. Right now its warm enough for them to grow happily before the harsh summer heat kills them (or at least makes them dormant). Theyre growing on the rocks by the stream and on a couple of the trees. I notice they seem to grow best on the trees with the rough bark. I think the smooth barked trees dont hold enough moisture for it to survive. If we spot any of it growing on the pavements, we unfortunately have to spray it (stupid tripping hazard OHS rules), so we either break out the weed killer, but if I get the option I prefer to spray copper. Its less harmful to the environment and does the same job. Only problem with it, is it can stain the pathway for a while, but it wears off eventually.
