Growing Details: Common Name: Plum Genus: Prunus Cultivar: Opal Skill Level: Beginner Exposure: Full sun, Partial shade Hardiness: Hardy Soil type: All, except very damp Rootstock: St. Julien A Other Notes: Self Fertile Description: Opal Plums are early cropping plum trees and in a good year you can look forward to the first fruit being ready at the end of July. Because they are so early, Opal plums mature quite fast.They are self-fertile.Opal Plum is quite happy to bear a heavy crop all by itself. It is also reassuringly regular in the size of harvest each year. These trees will grow to 10-12ft max. As with all trees from the prunus family, the leaves will start to appear autumnal and slightly shabby from mid July onwards. This is not a disease, but is mainly due to this years contrasting weather conditions and will not affect the performance of the tree. Polliniation: It is self-fertile and will produce fruit by itself.
