Hi - we've got a Peppy/Agonis flexuosa we planted from a pot about a year ago (Duncraig in Perth). The leaves have gone quite yellow and now there are white spots on the trunk. Any suggestions on causes/remedies? Thanks!!
Ailing plants can be caused by so many localised environmental factors that we do not attempt to diagnose then on-line. Our suggestion is to take a cutting and photos to your local nursery where they can ask you lots of questions about your local conditions - they will also have insights to local conditions as well making it far more likely they will be able to give you an accurate diagnosis. We could make a guess based on general horticultural knowledge, but that won't necessarily help you.
