That's some feat Carol, growing an avocado from seed to a 300 fruit harvest
I have trouble even writing avocado, I keep wanting to put a ''d'' and a ''r '' in there! My natural soil is not deep here, except in my built up veggie beds and also I have surface water during the winter, so it could suffer root rot.On top of that, the winter gales are salt ladden and the trees would't appreciate that, though I did read somewhere that there is a variety that is suitable for coastal planting.
Possums here are soul destroying, they even strip the lemons of rind during the winter.Come summer, they get almost all my plums and every single apricot and in doing so, break the permanent fruit spures.After the harvest they start stripping the leaves.
I use 3 traps constantly set, but the current lot are very evasive.I relocate any that I catch.
