This creates a dense cover for wildlife. It may, however, be undesirable for windbreaks or plantings where continued cultivation is necessary. Nursery propagation is from seed. The seed should not be allowed to dry out from the time it is cleaned until it is planted. Diseases of the leaf and stem are common and may cause serious defoliation some years.
Aphid damage is common.
A total of five accessions have been tested at the Pullman Plant Materials Center. The most desirable accession, P- 13252, was tested at the outlying stations and in field planting trials. More accessions will have to be tested before an entirely satisfactory long-lived American plum is found for this area. P-7349 Russian mulberry is a tall shrub or small tree. The leaves are extremely variable and many different shapes may be found on one plant.
