In winter, most houseplants grow slowly. Disturbed roots take longer to recover, and fresh soil stays wet for a long time, which is a recipe for root rot.

Make a note for spring if you see:

  • roots coming out of the drainage hole or circling the pot,
  • water running straight through without soaking in,
  • soil drying out in a day or two,
  • a plant so top-heavy it tips over.

When the time comes, go up only 1 to 2 inches in pot size. A much bigger pot holds more water than the roots can use.

The exceptions: root rot, a broken pot or pests in the soil. Those can't wait.
