Grafting is a valuable tool for the propagation of plant cultivars. This technique of joining two plants to continue their growth as one is commonly practiced on apple trees and is critical to the preservation of heirloom apple varieties. To learn more about the art and science of grafting, join John Bunker of Fedco Trees in Waterville, Maine, on Saturday, April 10, for a daylong PHA workshop on reviving heirloom varieties through grafting. John has been called an “apple whisperer” for his ability to coax viable scionwood out of old apple trees. For more information on the workshop, or for instructions on collecting your own scionwood for the workshop, call 508-693-9426.
