Wet the root ball completely
Apply water slowly in several passes. For a strongly repellent ball, brief controlled immersion can restore wetting, followed by complete drainage.

A dried-out bonsai
A dry surface is common; a fully dry, water-repellent root ball is an emergency. Confirm whether living tissue remains before adding further stress.
01 / Method
Rehydrate slowly, then wait.
A weakened tree usually needs stable light, correct moisture and time—not simultaneous pruning, feeding and repotting.
Reduce stress, not all light
Shelter from hot wind and harsh sun while retaining bright conditions appropriate to the species. Do not seal the tree in stagnant darkness.
Do not prune the evidence away
Wait for a biological response before removing branches. Scratch tests damage bark and should be minimal and inconspicuous.
02 / Triage
Safe sequence
Check the species and season.
Read moisture below the surface.
Stabilise light, temperature and wind.
Change one variable, then observe.
