Hi,
I have a 6 year old Washigton navel orange tree in my
Melbourne garden. Good sunny position, good soil, no grass
arund the tree, watered well, fertilsed with citrus food 3 times
a year and prunned. Looks very healthy and produces fruit.
Unfortunately in autmn and early winter is drops fruit and
very few if any) manage to ripen fully. I thought it might simply
have been the wind but it still has lost 15 oranges over last week,
without much wind.
Help!
Alex
