Pollinating the Santa Rosa plum tree
I have 2 (I think)Santa Rosa Plum trees that are over 7 years old. They're about 15 feet tall. They are covered in blossoms every year but I've only had about 3 small plums which disappear before they're very big. I have been told to get a Methley Plum to help with the pollinating. Is there any other plum that would help to pollinate these. Or do you know if there is maybe some other problem? Thanks in advance.
