My 20 plus year old Ficus tree drops berries nearly all of the time. Very messy. Previously this would happen and would last only a week or two. I slow water the tree once a week summer months,once every two weeks winter. Is this to much for southern AZ ? Is there anything I can do to solve this problem?
Unfortunately for your case, this is a sign that the tree is very healthy, and aside from methods are can be very toxic to the area around the tree, there is no good method for controlling this.
