Signs of Overwatering
Because bonsai pots are shallow with little soil volume, waterlogging shows up fast as yellowing leaves and a consistently soggy surface.
Signs of Underwatering
The small glossy leaves droop and can drop suddenly - the limited soil volume in a bonsai pot dries out much faster than a regular houseplant pot, so checking daily matters.
Adjusting for the Seasons
Because the root system is intentionally kept small and shallow by the bonsai pot, watering needs are checked far more frequently (often daily in summer) than a ficus grown in a normal pot.
Pro Tip
Check the soil daily rather than following a fixed schedule - the small pot and thin soil layer that make a bonsai look elegant also mean it can swing from wet to bone-dry much faster than a normal potted plant.
