Do You Bury Air Roots When Repotting Orchids

You do not bury air roots when repotting orchids.

It’s one of the most common mistakes new orchid owners make, and it can actually cause more harm than good.

Air roots are simply your orchid’s way of adapting to its natural environment, and burying them beneath the potting mix can lead to rot and suffocation.

In this post, we’ll break down exactly what air roots are, why you shouldn’t bury air roots when repotting orchids, and how to repot your orchid properly to keep those roots healthy.

Let’s dig in and get your orchid thriving.

Why You Shouldn’t Bury Air Roots When Repotting Orchids

So, why exactly is it a bad idea to bury air roots when repotting orchids?

It all comes down to how these specialized roots function and what they need to survive.

1. Air Roots Are Designed for Airflow

Air roots, also known as aerial roots, are naturally adapted to grow outside of the potting medium.

They have a thick, spongy outer layer called the velamen, which is designed to absorb moisture directly from the humid air.

When you bury air roots when repotting orchids, you’re cutting off their primary source of hydration.

The velamen can’t function properly when it’s constantly wet and packed in bark, so the root essentially suffocates.

Additionally, the velamen helps the orchid cling to trees in the wild, and burying it disrupts that natural function.

2. Burying Air Roots Increases the Risk of Rot

Another major reason you don’t bury air roots when repotting orchids is the risk of root rot.

Orchid roots, especially air roots, need to dry out quickly between waterings.

When they’re buried deep in a pot, they stay wet for much longer than they should.

This constant moisture creates the perfect breeding ground for harmful fungi and bacteria.

Over time, the air root will turn mushy and brown, and that rot can quickly spread to the rest of the plant’s root system.

It’s a fast track to killing your orchid, so it’s best to leave them above the mix.

3. Air Roots Provide Structural Support

In their natural habitat, orchids use air roots to anchor themselves to tree branches.

These roots are tough and wiry, and they help the plant stay upright in strong winds and heavy rain.

So, when you bury air roots when repotting orchids, you’re actually weakening that structural support.

The roots lose their grip and rigidity, and your orchid may become unstable in its new pot.

Leaving them exposed lets them continue to anchor the plant and keep it securely in place.

4. Repotting Stress Is Reduced

Repotting is already a stressful event for any orchid.

The roots are disturbed, the growing medium changes, and the plant has to adjust to a new environment.

If you bury air roots when repotting orchids, you’re adding even more stress to an already sensitive situation.

Those buried roots will struggle to adapt, and the plant may go into shock.

Leaving them exposed, on the other hand, helps the orchid recover more quickly and settle into its new pot with minimal fuss.

How to Properly Handle Air Roots When Repotting Orchids

Now that you know you shouldn’t bury air roots when repotting orchids, let’s talk about what you should do instead.

1. Leave Them Uncovered

The simplest and most effective approach is to just leave them as they are.

Do not bury air roots when repotting orchids, even if they seem awkward or stick out at odd angles.

Place the orchid in its new pot and pack the fresh bark or moss around only the roots that were originally below the surface.

The air roots can hang over the edge of the pot or shoot upwards, that’s perfectly okay.

2. Mist Them Regularly

Since air roots get their moisture from the air, you can help them out by misting them regularly.

A light spray with a water bottle every few days keeps the velamen hydrated and happy.

This is especially important right after repotting, as the orchid is adjusting to its new environment.

Just make sure the roots have time to dry out between mistings to avoid issues.

3. Consider a Soak for Severely Dehydrated Air Roots

If you notice that some of your air roots look shriveled and grey, they might be dehydrated.

In this case, you can soak them briefly before repotting.

Use a bowl of room-temperature water and let the air roots sit in it for about 15 minutes.

This helps plump them up and makes them more flexible for handling during the repotting process.

After the soak, let them dry completely before you place the orchid in its new pot.

4. Trim Only Dead or Rotting Roots

It’s totally fine to trim away air roots that are already dead, mushy, or completely dry and crispy.

Use sterilized scissors or pruning shears for a clean, safe cut.

Just be sure not to cut any firm, healthy roots, even if they’re air roots.

You only want to remove the parts that are beyond saving, not healthy tissue.

Common Myths About Burying Air Roots When Repotting Orchids

There are a few myths floating around that make people think they should bury air roots when repotting orchids.

Let’s clear those up.

1. Myth: Burying Air Roots Helps Them Grow Better

Some folks think that if the air roots are in the potting medium, they’ll absorb more water and nutrients.

That’s simply not true.

The velamen on air roots is designed for air, not for soil.

When they’re buried, they don’t absorb better, they just rot faster.

2. Myth: Air Roots Mean the Orchid Is Unhealthy

Seeing air roots sticking out of the pot doesn’t mean your orchid is sick.

In fact, it’s a sign of a healthy, vigorous plant that’s trying to grab more moisture and stability.

It’s completely natural for orchids to produce air roots as they grow.

3. Myth: You Can Train Air Roots to Grow Into the Pot

You might be tempted to curl those long air roots down into the pot, but you shouldn’t.

Forcing air roots into the mix goes against their nature.

They’ll likely just die off because they can’t handle the constant wetness of the potting medium.

So, Should You Bury Air Roots When Repotting Orchids?

You should not bury air roots when repotting orchids, and the evidence is clear.

Burying them leads to rot, suffocation, and increased stress for your plant.

Instead, leave them exposed so they can continue absorbing humidity from the air.

Mist them when needed, and always use a well-draining orchid mix for the roots that belong in the pot.

With this approach, you’ll help your orchid stay healthy and thrive after every repotting session.

Remember, air roots are a sign of a happy orchid, so let them be free.
