Do I have to spray my olive trees every year?
 
A. Yes. There is a window of time in the spring when olive trees can be effectively treated to inhibit fruit production. This window of opportunity begins at the end of January / the beginning of February and ends in March.
 
Unfortunately, once the bud becomes a flower and the flower falls off the tree, (with a tiny olive taking its place) the window of opportunity is over and you’ll have to wait until next year.
