Asked September 25, 2013, 3:16 PM EDT

About 5 years ago I bought and planted a Mount Royal and a Toka Plum in my back yard which is protected by a 6 foot fence as well as housed and garages every year they bloom but never are there any plums. I am in NE Minneapolis on the big hill, when I lived in South Minneapolis I had no problems. I am starting to think about cutting them down and starting over.

Expert Response

European plums (Mount Royal), are self fertile.  That means they bear fruit even if there isn't another plum tree nearby.  However, they often produce larger crops when another variety of European plum is present.

(Mount Royal will not pollinate Toka and vice versa because they are incompatible.)

On the other hand, hybrid plums (Toka) are self sterile.  That means they will not bear fruit unless another hybrid plum is present.  So instead of cutting Toka down, try planting another hybrid plum such as Superior or South Dakota nearby.

We don't know why Mount Royal isn't bearing fruit even though it flowers.  The most likely explanation is an absence of pollinating insects, due perhaps to a scarcity of pollinators or unfavorable weather conditions at bloom time that limit their activity.

Are the trees growing in full sun?  Plum trees growing in the shade may fail to bear fruit.
