This tree is ‘stunted’ at around 900mm high, while a 2nd tree in a different spot is over 2 mtrs tall and not having any darkening on the leaves.
Answer:
Hi Mal? What is polagranite?? This plant is not deathly ill, but there is a problem. The leaves say: “nutrient imbalance”. I just haven’t got enough info to help you. Dig a few holes near the roots to see if the soil is water-repelling. If it is dry, try some Seasol Super Soil Wetter. I have no idea what your soil is like. I would water the bejesus out of it & see what happens in Spring. Don.
