We noticed our quince (Chaenomeles speciosa ‘Cameo’) hedge was infected---almost a dozen branches with crisp, dried leaves---and took action yesterday to help prevent more damage. The best method is to prune out the diseased wood, 8-12” below the infected area, and dispose of the clippings in the garbage (not compost). It’s also important to clean your tools with a bleach solution (1 part bleach: 9 parts water) between each and every cut.
