Troubleshooting
Field Elm Bonsai problems — and how to fix them
Field Elm Bonsai (Ulmus minor) 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.
Dutch elm disease
Field elm is vulnerable to this fungal disease spread by bark beetles. Watch for sudden wilting and yellowing of branches; remove and dispose of affected wood and keep tools clean.
Inner twig die-back
Dense outer growth shades interior twigs, which weaken and die. Thin the canopy periodically so light reaches the inner ramification.
Leaf scorch
Underwatering in summer heat browns the small leaves quickly. Maintain consistent moisture; this thirsty species shows stress fast in shallow pots.
Coarse, leggy growth
Insufficient light or unpinched vigour produces long internodes and large leaves. Keep it in full sun and prune frequently to maintain refinement.
