If the seed is directly sown outdoors, it may take two cold periods before germination is initiated. Propagation from root cuttings is not usually successful. Transplanting from the wild is problematic because roots are easily damaged. Another problem with container-grown trees is the restricted taproot and resultant stunting. Using long, narrow pots can alleviate this problem.
Pawpaws have very few pest problems.
Usually, however, so little damage is done that this is not a serious problem. Other reported pests include earwigs, slugs, San Jose scale, and tent caterpillars. San Jose scale can be controlled with dormant oils. This only occurs during periods of high humidity. Dense foliage and lack of proper ventilation contribute to this condition, so proper spacing and pruning should eliminate it.
