Introduction
With the houseplant boom in full swing, more plant lovers are discovering the quirky charm—and occasional confusion—of aerial roots. Whether it’s a curious tendril sprouting from your Monstera or a wandering root clinging to your wall, these unique growths are grabbing attention in indoor jungles everywhere.
But what exactly are aerial roots, and how should you care for them indoors? In this guide, we’ll unpack their purpose, show you how to manage them safely, and share styling tips to turn those roots into an intentional part of your decor. Let’s take the mystery out of these adventurous plant parts.
Understanding Why Plants Produce Aerial Roots and Their Functions
Aerial roots are roots that grow above the soil surface. Unlike traditional roots that stay hidden beneath the surface, these roots are exposed and often grow along walls, supports, or into the air. Several types of houseplants naturally produce them, including:
- Monstera (e.g., Monstera deliciosa)
- Philodendrons
- Orchids
- Pothos
While they might seem unruly or unexpected at first, aerial roots play essential roles:
| Function | Description |
|---|---|
| Support | Help climbing plants anchor to structures like trees, moss poles, or trellises |
| Moisture & Nutrient Collection | In humid environments, aerial roots can absorb water and nutrients from the air |
| Air Exchange | Especially in epiphytic species (like orchids), aerial roots help with breathing |
In short, aerial roots are not a sign of poor plant health—in fact, they often indicate a thriving and growing plant!
Deciding When to Trim or Redirect Aerial Roots for Aesthetics
While aerial roots are beneficial, it’s okay to want a neater look indoors. There are times when trimming them is appropriate:
- The root is brittle, dead, or dry
- Roots are becoming a tripping hazard or interfering with walking paths
How to Trim Safely:
- Use clean, sharp pruning shears or scissors to prevent infection
- Cut close to the stem but avoid damaging it
- Sanitize tools before and after use
However, if the root is healthy but simply in the wrong spot, consider redirecting instead of cutting:
- Bury the root into the topsoil of the pot
- Guide it onto a nearby support with a soft tie
This gentle approach helps maintain plant health while keeping your space tidy.
Training Roots Onto Supports and Ensuring They Remain Moist
Many indoor plants with aerial roots are climbers by nature. Helping them climb allows for healthier growth and a tidy appearance. For detailed training advice see our Training Supports & Plant Shaping Guide.
Recommended Plant Supports:
- Moss poles
- Coco coir totems
- Wooden stakes
- Wall-mounted trellises
Training Tips:
- Secure roots loosely with soft garden ties, velcro strips, or plant-safe clips
- Use the two-finger rule: leave enough slack to fit two fingers between the tie and the root
- Mist aerial roots regularly to promote adhesion and hydration
Over time, roots may naturally wrap around the support. Be patient—some plants take a while to “get a grip.”
Increasing Humidity to Help Aerial Roots Adhere and Absorb Water
Humidity is essential for aerial root vitality, especially for tropical plants like Monstera and Philodendron. In low-humidity environments, aerial roots may dry up or remain dormant.
Ways to Increase Indoor Humidity:
- Pebble trays: Set pots on trays filled with pebbles and water (just below the pot’s base)
- Humidifiers: Especially helpful in winter months or dry climates
- Grouping plants: Clusters create microclimates with higher humidity levels
- Regular misting: Especially in mornings to prevent mold
Observe your plants: if aerial roots feel dry or look shriveled, tweak your routine to add more humidity.
Avoiding Constriction or Damage to Roots by Tying Too Tightly
While training roots can be beneficial, it’s important to be gentle. Tying too tightly can damage the root and hinder future growth.
Risks of Over-Tightening:
- Choking growth and reducing circulation
- Bruising or slicing into the root tissue
- Creating open wounds that could attract pests or disease
Safe Materials for Tying:
- Soft garden tape
- Velcro plant ties
- Reusable plant-safe wire wrapped in cloth
Again, the two-finger rule applies—if you can’t slide two fingers under the tie, it’s too tight.
Managing Roots That Attach to Walls or Furniture and Safe Removal
If your plant’s aerial roots latch onto paint, wallpaper, or furniture, don’t panic—it happens! Roots are simply seeking support or moisture. Here’s how to manage or remove them safely.
Prevention Tips:
- Keep climbing plants a few inches away from porous walls and raw or unsealed wood
- Use backdrops like moss poles or lattice boards as vertical growing alternatives
To Detach Roots Safely:
- Soften the area by placing a damp cloth on the root for several minutes
- Gently lift the root using a cotton swab or blunt butter knife
- Never pull or scrape harshly—it can damage the paint and the plant
After removal, mist the root and redirect it onto a support to give it a new “home.”
Creative Styling Options to Celebrate Unique Root Structures
Instead of hiding aerial roots, why not embrace them as part of your home’s design? With a little creativity, roots can become a living sculpture in your space.
Styling Ideas:
- Glass planters: Showcase trailing roots in clear containers for a modern look
- Wall-mounted trellises: Let roots climb across artistic supports
- Minimalist decor: Use aerial roots to add organic texture to clean spaces
- Boho styling: Pair aerial roots with woven baskets, macramé, and earthy tones
Just remember—style should never come at the cost of plant health. Always prioritize proper care before aesthetics.
Conclusion: Harmoniously Living with Aerial Roots Indoors
Aerial roots are a normal and manageable part of many houseplants. With the right approach, they can be guided, trimmed, styled—or simply appreciated for what they are: signs of your plant’s growth and adaptability.
Takeaways:
- Recognize aerial roots as helpful, not harmful
- Decide between trimming or redirecting depending on plant health and aesthetics
- Use supports, moisture, and gentle handling to keep roots thriving
- Explore styling options that turn roots into a conversation piece
With a little care and creativity, those wild little roots can fit harmoniously into your space—and even add to its charm.
