I have a client who has stanley plum trees and every year the fruit show a small pinhead sized black spot as it matures. Then the juice starts dripping out then they dry up and die.
sort by best latest
I'm not an expert on the care of fruit trees, but can I suggest that you go to the following site and have a look at the instructions they give on 2 kinds of disease for the plum tree - http://www.ehow.com/how_7684720_treat-fungus-plum-...
This next site suggests that the black spot may be caused by a bacterial spot -Xanthomonas pruni.
This site deals specifically with the disease - http://www.uri.edu/ce/factsheets/sheets/peachbact spot.html.
Hope this is of some help.
