Troubleshooting
Yew Bonsai problems — and how to fix them
Yew Bonsai (Taxus cuspidata) 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.
Root rot from wet soil
Yew is exceptionally sensitive to standing water. Use a free-draining mix, never let the pot sit in a saucer, and ease off water in cool weather.
Toxic clippings and berries
Trimmings and seeds within the red arils are lethally poisonous. Bag and dispose of prunings safely and site the tree away from pets and children.
Summer scorch in full sun
Intense afternoon sun can bronze or brown the foliage. Give afternoon shade or bright dappled light during heat.
Slow recovery if over-pruned
Because it grows slowly, heavy work at the wrong time weakens it. Do major pruning in spring and avoid removing too much foliage at once.
