Troubleshooting
Deutzia 'Nikko' problems — and how to fix them
Deutzia 'Nikko' (Deutzia gracilis 'Nikko') 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.
Reduced flowering
Pruning at the wrong time removes flower buds; prune immediately after flowering since blooms form on old wood.
Bare, woody centre
Old plants open up in the middle; cut a portion of the oldest stems to the base after flowering to rejuvenate.
Leaf scorch in drought
Browning leaf edges on hot, dry sites; mulch well and water during prolonged dry spells.
Unwanted spreading
Low stems can layer themselves and creep; lift and remove rooted shoots to keep it within bounds.
