Nothing brightens up a home (and your mood!) quite like houseplants. Whether it’s a potted monstera, an aloe plant, or a ficus tree, indoor plants have this way of turning any living space into a tranquil sanctuary—one with purified air, of course! As you give your houseplants the sunlight, water, and humidity they need, they’ll eventually need more room to grow. Just like we outgrow our homes, our houseplants do, too!
Because plant roots expand as they grow, moving them to a larger pot gives them the space they need to become bigger and stronger. Not to mention, upgrading your houseplants’ residence is an opportunity to refresh their current potting mix and replenish all the depleted nutrients.
But knowing when to repot your houseplants can be tricky. There’s a fine line: If you repot them too soon, you’ll stress them out, but if you wait too long, your plant will start to struggle. Luckily, there are a few telltale signs that signal it’s time for a new pot. Follow these tips, and your leafy friends will thank you—and soon thrive!
When to Repot Houseplants
The best time to repot a healthy houseplant is during its active growing season, which is generally early spring through early summer. Since plants produce new roots and leaves in the spring and summer, their post-repotting recovery and adjustment periods are typically smoother. During this time, plants also get more sunlight and absorb nutrients more easily, giving them the energy to bounce back.
In most cases, the winter season and mid- to late-summer in extreme heat aren’t ideal for repotting. During the winter, indoor plants typically grow more slowly—or not at all—since they receive less light and, therefore, go somewhat dormant. So, switching up their home when they’re in a vulnerable state will likely do more harm than good. Likewise, during sweltering summer days, repotting can shock your plants’ system.
That said, there are certain situations (more on that below) where repotting is necessary outside of spring. Darryl Cheng, creator of the plant-care website House Plant Journal and bestselling author of The New Plant Parent and The New Plant Collector, explains that a more effective method for determining timing is focusing on your plants’ individual needs, not a finite season. “In fact, putting off repotting simply because ‘it's not spring yet’ can be detrimental to a severely root-bound plant,” he says.
Signs It’s Time to Repot Your Houseplants
While a plant’s growing season is generally the best time for repotting, in certain situations, you might need to increase its pot size during other times of year. Here’s how to tell whether your houseplant needs a new pot:
The pot is damaged.
First things first, if your plant’s pot is damaged, take it as a sign to upgrade. A cracked or broken pot isn’t just visibly unappealing, it’s also harmful to your houseplant. Ashaky foundation won’t support the root system or properly hold the soil, so moving your plant to a sturdier pot will protect its roots and maintain its moisture levels.
The roots are visible.
Another significant sign of repotting? Visible roots. If you notice your plant’s roots growing out of the drainage holes or circling the inside of the pot, it’s likely root-bound. “When roots have overtaken most of the pot volume, you may notice the soil drying faster than usual, or growth is stunted,” Cheng explains. Relocating your houseplant to a bigger pot will give its roots more breathing room to expand and fresher nutrients to absorb.
The soil has trouble drying.
Consistently wet soil—we’re talking days after watering—often means that the soil is compacted or poorly aerated. Because soaked soil can increase the risk of root rot, putting your houseplant in a new pot with a fresh potting mix will restore its airflow and increase its access to fresh nutrients.
The soil has degraded.
With time, potting soil can turn dense, dusty, or depleted of its nutrients, which can lead to poor growth, root rot, or pest infestations. If you see a compacted texture, white mold on the surface, or space around the edges like the soil is pulling away, the degraded mix could use a refresh. Repotting your plant with fresh soil will improve its drainage ability and get its health back on track again.
The plant’s growth has stopped.
If an actively growing plant has suddenly stopped growing, its current home might be too small for it. Halted growth typically means that a plant doesn’t have the necessary space or nutrients to grow new leaves or stems. Once you move your plant to a larger pot, its growth will likely pick right back up.
The plant has grown too large.
Your houseplant could also have the polar opposite issue: too much growth. If the leaves and stems have grown larger than the pot, it might become difficult to evenly water it. By shifting it to a new pot that’s one or two inches larger, you’ll rebalance the plant for more consistent and even growth.
The plant dries out quickly.
If you find yourself watering your plant significantly more than usual, its roots might have overtaken the pot. With overgrown roots, there’s very little room left for soil to retain moisture, which can cause your houseplant to dry out rapidly. Repotting is the simple solution!
Water runs through the pot.
Root-bound plants have drainage issues that only a new pot can solve. When a plant’s root system has displaced most of the potting mix, water will pass through the drainage hole without reaching the soil. By repotting your houseplant with fresh soil, your plant will soon become hydrated and healthy again.
