Description: Prunus species may be rooted from dormant hardwood, softwood, semi-hardwood, or root cuttings. Semi-hardwood and softwood cuttings taken in summer root easiest. Germination of most seeds requires cold stratification.
Seed Collection: Collect fruit when it is filled out, firm, and its ripe color. Clean seeds from pulp and briefly air dry. (Seeds to be sown immediately in fall do not need drying.) Storage viability is maintained at 31-41 degrees.
Seed Treatment: For spring sowing, stratify seeds in moist sand for 30-60 days in a greenhouse, then cold stratify (36-41 degrees) for 60-90 days. Plant well before high temperatures.
Commercially Avail: yes
Maintenance: Water during droughts to prevent black knot disease.
