Check before lifting the can
Feel below the surface and consider pot weight, species, weather and root activity. A fixed weekly schedule ignores all four.

Watering bonsai
Correct watering begins with observation. Learn to distinguish a dry surface from a dry core, water completely and preserve oxygen around the roots.
01 / Method
Water the root ball, not the weekday.
A weakened tree usually needs stable light, correct moisture and time—not simultaneous pruning, feeding and repotting.
Water the complete root ball
Apply water across the surface until it drains freely. Repeat after a short pause when a very dry root ball initially repels water.
Let air return
Good substrate changes from wet to moist while retaining air. Never leave the pot standing permanently in runoff water.
02 / Triage
Safe sequence
Check the species and season.
Read moisture below the surface.
Stabilise light, temperature and wind.
Change one variable, then observe.
