Hinoki Cypress Bonsai problems — and how to fix them
Hinoki Cypress Bonsai (Chamaecyparis obtusa) 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.
Inner foliage dieback
Hinoki sheds interior and lower foliage if shaded or left unpruned, leaving bare branches. Maintain light penetration and thin the canopy; it does not back-bud readily on old wood, so avoid cutting back to bare branches.
Foliage browning from drought
Allowing the rootball to dry fully scorches the fine sprays. Keep the soil evenly moist, especially in summer heat and wind.
Root rot from poor drainage
Despite liking moisture, it rots in saturated soil. Use a draining mix and ensure the pot never sits in standing water.
Weak back-budding
Hinoki rarely produces new shoots from old bare wood, so structural pruning must be planned carefully — always leave green foliage on any branch you wish to keep.
