Repotting library
When & how to repot 10153 of the most-asked-about plants.
“When to repot”, “how to repot” and “what size pot” have a different answer for every plant. Pick a species for its real repotting frequency, the exact pot-size step, the right season, and the over-potting trap to avoid.
Start with the method, then size the pot.
The two questions every repot turns on are “does it actually need it?” and “how big a pot?”. These two guides answer both, and the calculator does the sizing for you:
- How to repot a plant — the complete step-by-step method — the model technique, soil, depth and aftercare.
- Pot size calculator — the right next pot size from the current pot and root spread.
- Root-bound plant — how to spot and fix it — the signs that mean “repot now”.
Plants that like being pot-bound
Snake plant, peace lily, hoya, clivia and many aroids flower and grow best when slightly crowded. Over-potting these into a big pot is the single most common way to rot them — repot only every few years, and only one snug size up.
