Stop automatic watering
Remove standing runoff, check drainage holes and wait for evidence from below the surface instead of adding more water by schedule.

Waterlogged bonsai
A persistently cold, wet root ball can suffocate fine roots and favour decay. The safe response depends on severity, season and tree strength.
01 / Method
Roots need oxygen as well as water.
A weakened tree usually needs stable light, correct moisture and time—not simultaneous pruning, feeding and repotting.
Improve conditions without panic
Increase appropriate light and airflow, shelter from prolonged rain if suitable, and avoid squeezing or repeatedly probing fragile roots.
Recognise an emergency
Foul smell, soft dark roots, a soft trunk base or rapidly collapsing shoots warrant prompt experienced help. Repotting a failing tree is high risk.
02 / Triage
Safe sequence
Check the species and season.
Read moisture below the surface.
Stabilise light, temperature and wind.
Change one variable, then observe.
