I germinated an orange pip, which I nurtured into a small tree. I had it in a pot, then about 18 or more years ago, I planted it into the ground and it is now about 9 feet tall. Three years ago it flowered for the first time but no fruit. Last year 1 orange did grow but remained green. This year the tree is almost in full flower and I have high hopes. What is the best way to promote good fruit growth?
