How do I know when to repot a houseplant?
Repot a houseplant when roots circle tightly inside the pot, grow from the drainage holes, dry out unusually fast, or the plant repeatedly wilts despite proper watering. Move it into a pot only slightly larger and use fresh potting mix. Repotting is usually best during active growth, but a severely waterlogged or root-bound plant may need attention sooner.
When should you repot a houseplant?
Repot a houseplant when its roots have filled most of the container, are circling tightly, or are growing through the drainage holes. Other signs include soil that dries out very quickly, a plant that becomes unstable, or repeated wilting even though you are watering correctly.
Slide the plant gently from its pot to inspect the root ball. Healthy roots are usually firm and light-colored, though color varies by plant. Roots that are mushy, hollow, or unpleasant-smelling may indicate excess moisture or root rot.
Choose a container only slightly wider than the current one. A much larger pot can leave a large volume of wet soil around the roots. Select a fresh mix suited to the plant, and make sure the new container has drainage holes.
How to repot
- Prepare the new pot and fresh potting mix.
- Remove the plant carefully without pulling hard on the stems.
- Loosen tightly circling roots with your fingers.
- Trim only damaged or rotten roots with clean scissors.
- Set the plant at its previous soil level.
- Fill around the roots and water according to the plant's needs.
Spring and summer are often convenient because many plants are actively growing, but you do not need to repot on a fixed annual schedule. A healthy plant can remain in the same pot for years if it has suitable soil, drainage, and room for its roots.
