Polly Hill Arboretum hosts an apple grafting workshop next Saturday, April 10, from 10 a.m. to 4 p.m. John Bunker of Fedco Trees, known in some circles as an “apple whisperer” for his natural gift for working with apple trees, will lead the workshop. A valuable tool for the propagation of plant cultivars, grafting is a technique of joining two plants to continue their growth as one on a single plant. Grafting is particularly useful in the preservation of heirloom apple varieties.

There will be a slow food potluck dinner following the talk at a private home. For details on the workshop or the dinner,including the preparatory materials needed for the workshop, call 508-693-9426.Cost for the workshop is $85, or $75 for arboretum members.
