Troubleshooting
Prunus maackii problems — and how to fix them
Prunus maackii (Prunus maackii) 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.
Toxic foliage and pits
Wilting leaves, twigs and the seeds inside the fruit contain cyanogenic compounds dangerous to dogs and cats. Keep prunings cleared up and discourage pets from chewing fallen leaves and stems.
Silver leaf and canker
Like other Prunus it is prone to silver leaf fungus and bacterial canker, both entering through wounds. Prune only in summer when spores are least active and the tree heals fastest, and remove infected wood promptly.
Bark damage spoils the display
The prized peeling bark is easily scarred by strimmers, mowers and tight ties, marring its main ornamental feature. Keep a mulched, grass-free collar around the base and check stakes and ties regularly.
Aphids and leaf-curl pests
Cherries attract aphids that distort young foliage and excrete honeydew. Tolerate minor infestations, encourage natural predators, and hose off or treat heavy colonies on young trees.
