Troubleshooting
Prunus 'Accolade' problems — and how to fix them
Prunus 'Accolade' (Prunus 'Accolade') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Silver leaf and bacterial canker
Like all Prunus it is vulnerable to silver leaf and canker entering through cuts; prune only in dry summer weather when active, and avoid large wounds.
Early-bloom frost damage
Its very early flowers can be browned by hard late frosts; choose a sheltered position out of frost pockets to protect the display.
Aphids
Cherry blackfly distorts spring foliage; tolerate minor infestations, hose off colonies and encourage natural predators rather than reaching for sprays.
Rootstock suckers
Grafted trees may produce suckers from the rootstock around the base; remove them cleanly at the source as they appear to keep the tree's shape.
