When Should You Repot a Houseplant?

Repot a houseplant when its roots have outgrown the pot, which shows up as roots coming out of the drainage holes, water running straight through, or growth that has stalled. Most plants need repotting every one to three years, and spring is usually the best time.

What are the signs a plant needs repotting?

• Roots growing out of the drainage holes or circling on the soil surface
• Water rushing through the pot without soaking in
• The plant is top-heavy and tips over
• Soil dries out unusually fast
• Growth has slowed even though light and watering are fine
• Pulling it out shows a dense mass of roots with little visible soil

How often should I repot?

Fast-growing plants like pothos and monstera may need a bigger pot every year or two. Slow growers like snake plants and ZZ plants can stay for several years. Refreshing tired soil is also a reason to repot, even into the same pot.

What is the best time of year?

Spring and early summer, when the plant is growing and recovers fastest. Avoid repotting in the middle of winter unless there is an emergency such as root rot.

How much bigger should the new pot be?

Go up only one to two inches in diameter. A pot that is too large holds more wet soil than the roots can use, which raises the risk of rot.

Should I repot a plant that is sick?

Only if the problem is in the roots or soil, such as root rot. Repotting a plant that is stressed for other reasons can add stress.
