Pawpaw propagation and nursery sources slide

Slide 10:  Historically, pawpaws have been a difficult tree species to propagate. What appear to be small pawpaw trees in a patch can often be rootsuckers that have poorly developed root systems and often do not survive transplanting. Seed is desiccation sensitive and requires stratification. Freshly cleaned seed should be stratified for at least 3 months at 5°C in moist peat moss in ziplock bags prior to planting. Commercial clonal propagation of cultivars is usually via chip budding or whip and tongue grafting onto seedling rootstock. Many nurseries produce pawpaw trees for sale in containers. We usually do not recommend purchasing bare root pawpaw trees from nurseries. However, some reputable nurseries do produce high quality bare root trees and these nurseries will guarantee tree replacement if the tree dies.
