The fruit is very important to wildlife in the winter, so harvest sparingly. As consuming large quantities of cramp bark fruit may cause stomach discomfort, this is a win-win.

For the bark, harvest young branches that still retain their copper color. As Cramp Bark blooms in early spring on old wood, pruning or harvesting of branches in late summer, fall, or winter may sacrifice next year’s blooms.

When harvesting the bark, gather sparingly, as a little goes a long way with this potent bark.

When harvesting from cultivated varieties in the landscape, harvest in spring, after the bloom has finished. Harvest branches that did not make flowers as this won’t sacrifice the fall’s fruit. Harvesting may also consist of pruning and shaping these lovely ornamental shrubs. This too is best done in late spring after the blooms have finished.

Take the harvested branches and expose the bark’s inner cambium layer by peeling the bark. A sharp knife or potato peeler may work well.
