g'day, I'm new to permaculture but have been studying like mad since I discovered it a few months ago, I am about start designing my backyard (1000m2 urban block) into a permaculture garden and upon identifying the existing trees I discovered that the beautiful big tree right in the middle (camphor laurel) is actually a pest and is toxic and allelopathic according to some resources! I was going to use it as a nurse tree for a small food forest but now I am stuck! there are so many different clashing opinions if it is allelopathic or not, that it kills fish and birds? What should I do pull it out???
