Moha7 — Houseplant Care Basics | moha7.com
The ordered repotting procedure: when to do it, how to size the new pot, what soil to use and how to care for the plant afterwards.
Houseplants usually need repotting every 1-2 years, when roots circle the pot or grow out of the drainage hole. Those two signs are the trigger: a root-bound plant dries out faster, drinks more, and outgrows the soil volume that used to buffer moisture between waterings.
Step 1 — timing: choose a moment when the plant is actively growing, and check the root ball first. Lift the plant gently; if roots are circling the inside of the pot or emerging from the drainage hole, it is time.
Step 2 — pot sizing: choose a new pot 2-5 cm wider in diameter than the old one. Going larger than that leaves excess soil that stays wet and suffocates roots — the same failure mode as overwatering, which is the most common cause of houseplant death.

Step 3 — soil: use a fresh mix rather than reusing compacted old soil. Compacted soil drains poorly and behaves like a pot without a drainage hole: water pools at the bottom and leads to root rot. Break up circling roots gently before setting the plant in the new mix.
Step 4 — aftercare: water with room-temperature water — it is kinder to roots than cold water straight from the tap — and keep the plant out of strong direct sun for about a week while roots recover. Then resume the normal rhythm: water when the top layer has dried out partially.
Step 5 — return to the light slot: place the plant back in the window orientation it had before. South-facing windows give the strongest natural light in the northern hemisphere, north-facing the weakest, and moving a plant to a much brighter spot immediately after repotting adds stress on top of root disturbance.
