Repotting a houseplant means moving it into a slightly larger container or refreshing the potting mix without disturbing roots more than necessary. The goal is not to use the biggest pot possible, but to restore root space, drainage, and soil structure.
Choose a pot only slightly larger
A container only an inch or two wider is often enough when roots fill the current pot. Jumping to a huge volume leaves a lot of wet mix around a small root ball and increases overwatering risk.
Moisten lightly and remove without pulling the stem
Water lightly beforehand if the root ball is bone dry and slide the plant out by handling the pot, not pulling the stem. Loosen circling roots only as needed and trim only dead or rotted tissue.
Use potting mix and drainage suited to the plant
The mix should hold and drain water according to the plant’s needs. Do not block the drainage hole with material that prevents flow, and do not rely on a rock layer as a substitute for well-structured potting mix.
Set the plant at the same depth and adjust watering
Do not bury the stem deeper than before unless the species tolerates it. Water to settle the mix when appropriate, then wait until the root zone approaches its normal moisture level before watering again.
