Wild Cherry Bonsai problems — and how to fix them
Wild Cherry Bonsai (Prunus avium) 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.
Poor response to hard pruning
Prunus avium dislikes large cuts and can die back or gum heavily. Prune lightly and often rather than making big reductions, and avoid major work on a stressed tree.
Fungal disease and canker
Blossom wilt, brown rot and bacterial canker are common. Prune only in dry summer weather, keep airflow good, and remove infected material to limit spread.
Root rot from wet soil
Cherries quickly rot in poorly drained, waterlogged media. Use a sharply draining mix and let the surface dry slightly between waterings, particularly in cool periods.
Sparse flowering
Too little sun, over-feeding with nitrogen, or pruning off flower buds suppresses bloom. Give full sun, feed for buds late in summer, and time pruning to spare flowering wood.
