Repotting
Repotting is the process of moving a plant into a new container, typically with fresh soil, to give its roots more room to grow and to refresh the growing medium. It is one of the most impactful maintenance tasks a houseplant owner can perform.
What Does It Mean?
Repotting involves carefully removing the plant from its current pot, loosening compacted roots, trimming any dead or rotting roots, and placing the plant into a slightly larger container with fresh potting mix. It is not always about upsizing; sometimes a plant is repotted into the same size container simply to replace exhausted or compacted soil. The best time to repot most houseplants is in spring, when active growth resumes.
Why It Matters
Over time, potting soil breaks down and compacts, reducing aeration and drainage. Nutrients become depleted, and salt buildup from fertilizers and tap water can reach harmful levels. Repotting restores a healthy root environment, gives roots room to expand, and often triggers a noticeable burst of new growth in the weeks that follow.
How to Apply It
Choose a new pot that is only one to two inches larger in diameter than the current one, as oversizing creates excess soil that stays wet and invites root rot. Water the plant a day before repotting to reduce transplant stress, and use a fresh mix appropriate to the species. After repotting, water thoroughly and keep the plant in a shaded spot for a week to allow roots to recover before resuming normal light and feeding schedules.
Examples
- •Moving a Rubber Plant from a six-inch pot to an eight-inch pot with fresh aroid mix in early spring.
- •Refreshing the soil of a large Bird of Paradise in the same pot after scrubbing away salt deposits.
- •Dividing an overgrown ZZ Plant into two pots during a spring repotting session.
