Troubleshooting
Japanese Cedar 'Cristata' problems — and how to fix them
Japanese Cedar 'Cristata' (Cryptomeria japonica 'Cristata') 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.
Reversion to normal foliage
Plain green shoots can overtake the prized crests. Prune out vigorous normal growth to encourage the fasciated cresting.
Foliage browning from drought
Crests and needles scorch when the root zone dries. Keep evenly moist, mulch, and water deeply during heat.
Winter bronzing
Cold turns foliage bronze-green; this is normal seasonal colour that reverses in spring, not a sign of disease.
Snow and wind splaying
Heavy snow or wind can open or break the upright form. Brush off snow and shelter from harsh winds; tie in if needed.
