I have planted a Pecan in Canberra about 5 years ago. It should suit the climate in theory in terms of chill hours and hot summer. Not sure about the clay soil though. The tree is doing well, but no sign of flower / fruit yet. Yes, I know it may take 7 year or so as a general rule for fruit, but I'm getting impatient for any signs. Does anyone grow /seen / has experience with pecans in this climate that can shed more light on fertilisation, soil treatment or any other advice?
