Orchids are stunning plants, but they come with their fair share of challenges. If you’ve ever repotted an orchid, you’ve probably wondered what to do with the roots.
Should you cut them, bury them, or leave them exposed? The wrong decision can mean the difference between a thriving plant and one that struggles.
Let’s break it down and make sure your orchid gets the best care possible.
The Unique Nature of Orchid Roots
Orchid roots are not like the roots of other houseplants. They’re designed to absorb moisture and nutrients from the air, not soil. That’s why they often grow above the potting medium and even out of the pot entirely.
These aerial roots aren’t just for show—they play a crucial role in the plant’s health. Understanding this is key to deciding how to handle them during repotting.
Should You Cut the Roots?
First things first: not all orchid roots are created equal. Some are healthy, while others might be dead or rotting. It’s essential to inspect the roots closely when repotting.
Healthy roots are firm and white or green, depending on moisture levels.
When Should I Cut The Roots?
If you find roots that are brown, mushy, or hollow, they’re dead or dying and should be cut off. Use sterilized scissors to trim them away—this prevents the spread of disease and rot.
But be careful; only cut the ones that are clearly unhealthy. Healthy roots, even if they look a little odd, should be left alone.
Should You Bury the Roots?
Orchids in the wild cling to trees and rocks with their roots exposed to air and light. Replicating this environment is crucial to their success. When repotting, you might wonder if you should bury all the roots in the potting mix. The answer is no.
When Should I Bury The Roots?
NEVER! Burying all the roots can suffocate the plant, leading to poor health and fewer blooms. Instead, use a loose, well-draining orchid mix, like bark or sphagnum moss. This will allow some roots to be buried while others remain exposed, giving them the airflow they need.
Should You Leave the Roots Exposed?
If your orchid’s roots are spilling out of the pot, don’t panic. These aerial roots are natural and beneficial. They help the plant absorb moisture from the air and participate in photosynthesis. Tucking all these roots into the pot might seem like a good idea, but it can actually harm the plant.
When Should I Leave The Roots Exposed?
If they’re healthy, aerial roots should remain free, and the potting medium should only cover a portion of the root system. When repotting, choose a slightly larger pot that can accommodate the orchid’s growth while still allowing some roots to stay exposed.
The Right Way to Repot
Repotting orchids isn’t as daunting as it seems when you know what to do.
A Balance That Works
The secret to healthy orchids lies in finding the right balance for their roots. A combination of trimming dead roots, partially burying the healthy ones, and leaving some exposed will give your orchid the environment it needs to thrive.
Orchids may seem finicky, but once you understand their unique needs, caring for them becomes much easier.
Next time you repot your orchid, you’ll know exactly what to do with the roots. With a little attention and the right approach, your orchid will reward you with beautiful blooms for years to come. Happy repotting!
