An empty pot is easiest to assess before fresh mix hides its interior. Look for cracks, blocked openings, persistent roots, and mineral deposits.
Wash first
Remove loose debris and scrub the container with water and an appropriate brush. Cleaning removes material that can interfere with later disinfection. Rinse and inspect the drainage openings from both sides.
If the previous plant had a disease problem, follow an extension service or suitable product's instructions for disinfecting that container material. Use only a correctly labeled product and method, including contact time, ventilation, protection, and rinsing requirements. Never mix cleaning chemicals.
Dry and store sensibly
Let pots dry before stacking where possible. Do not force tapered containers tightly together; trapped moisture and temperature changes can make them difficult to separate or damage fragile materials.
Keep cleaned pots away from contaminated soil and plant debris. Before reusing one, check its size against the new plant rather than choosing it simply because it is empty. Cleaning gives you a fresh starting point, but a spotless container can still be too large, too shallow, or unsuitable for the plant you intend to grow in it.
