Learn a pot's weight

Compare the same container with itself, not with a different plant beside it.

Water adds weight. For a small container that is safe to lift, this gives you a quick check that complements feeling the mix.

Establish two useful references

After normal watering and free drainage, lift the pot and notice its weight. Later, when a direct moisture check shows it is approaching the point at which that plant needs water, lift it again. The difference becomes familiar with practice.

Use a gentle lift close to the surface. Do not attempt this with a heavy, fragile, awkward, or hanging container. A kitchen scale can record a small pot's weight if you want a more consistent comparison, but no universal target number applies.

Roots, foliage, and the medium change over time, so reassess after repotting or substantial growth. A terracotta pot also stores and loses moisture differently from plastic.

Weight cannot tell you everything. Water might collect at the bottom while a small original root ball remains dry, or a decorative outer pot might contain hidden runoff. Check those possibilities when the plant's behavior does not fit the weight. Used together with observation, lifting is a useful habit. Used alone as an infallible test, it can hide the same problems as a calendar.
