The short answer
Watch where water goes and check the mix afterward. Very dry growing material can resist wetting, allowing runoff without moistening the whole pot.
Follow the water
Tilth Alliance describes dry soil that repels water: water may pool or pass through while material underneath stays dry. It suggests slow, steady watering with checks that moisture is entering the soil.
Remove the cover pot and work somewhere runoff is harmless. Watch for water following a gap at the edge. Check an accessible part of the mix afterward without digging through roots.
Slow down the observation
After a gentle application, note the water’s path, any pooling, the accessible deeper moisture and the pot’s feel. Pause if water pools. Remove runoff from around the pot.
This is an observation sequence, not a universal soaking recipe. An orchid in coarse bark and a leafy plant in fine mix do not have identical needs. Consult care guidance for the plant and growing medium before changing the method.
Describe the remaining problem
Runoff alone does not establish whether roots are crowded or whether the mix is suitable. If repeated watering leaves much of it dry, document the setup for plant-specific advice.
A useful note includes the plant name, pot dimensions, growing medium if known and what happened during watering. “Water leaves in seconds and the accessible center still feels dry” is more informative than “the drainage is good.” Include the last watering date; write “unknown” if you do not know it.
