Aerial Roots on Houseplants: What They Mean and Whether to Remove Them

What aerial roots actually are — and why plants grow them

Aerial roots are roots that originate above the soil line, from a stem, node, or trunk, and grow into open air rather than starting underground. They're not a sign of disease or distress on their own. They're an adaptation that evolved in plants native to rainforest floors and tropical canopies, where clinging to trees, absorbing moisture from humid air, and anchoring into whatever substrate is available are all survival strategies.

Botanically, aerial roots serve several distinct purposes depending on the species. Climbing plants like monstera, heartleaf philodendron, and pothos use them as holdfasts — stiff, clinging roots that grip bark, moss poles, or walls and allow the plant to climb toward brighter light. Epiphytes like phalaenopsis orchids and staghorn ferns use aerial roots to anchor onto host surfaces and absorb water and nutrients directly from rain and ambient humidity. Some tropical aroids, including certain monsteras, send thick aerial roots down toward the soil to supplement nutrient and water uptake — these are sometimes called prop roots.

Indoors, the same instincts operate, even if the context is different. A monstera in a pot will still push out aerial roots from its nodes because that's what its genetics tell it to do. It isn't searching desperately for soil because it's rootbound; it's doing what it does.

Which houseplants commonly produce aerial roots

**Monsteras (Monstera deliciosa and Monstera adansonii):** These are the most well-known aerial-root producers in the houseplant world. Thick, rope-like roots emerge from the nodes along the stem. In the wild they'd grip tree bark; indoors they'll droop through the air, rest on soil, or curl around a moss pole. They're perfectly normal and often quite vigorous.

**Pothos and philodendrons (golden pothos, heartleaf philodendron, philodendron brasil, philodendron birkin, satin pothos, arrowhead plant):** All of these climbers produce slender aerial roots at their nodes. You'll notice them especially on older, longer vines. When these roots are directed into water or soil, they'll readily take hold — which is exactly why these plants propagate so easily.

**Orchids (phalaenopsis orchid):** Orchid aerial roots are especially distinctive — plump, silver-green, with bright green tips when actively growing. Because phalaenopsis are true epiphytes, these roots are the primary way the plant absorbs water and humidity. They should never be buried, removed, or stuffed back into the pot. Healthy orchid roots roam freely over the rim of the container and that is exactly correct behavior.

**Hoya (hoya carnosa):** Hoyas produce small aerial roots from their nodes, particularly when humidity is higher or when a vine is in contact with a moist surface. These roots will happily anchor into a moss pole or climb a trellis.

**Staghorn fern:** This plant is essentially built around aerial root function — it anchors to mounting boards and absorbs moisture through its root structure. Aerial roots are the entire root system here.

**Lucky bamboo:** The reddish-orange roots that emerge from the stems of lucky bamboo and trail into water are aerial roots. They're healthy and necessary.

**Rubber plant and umbrella plant:** Mature specimens occasionally produce aerial roots from lower stem sections, especially in high humidity. These are more unusual indoors but entirely harmless.

**Inch plant (Tradescantia):** Vigorous stems will sometimes produce fine, hair-like aerial roots at nodes, particularly where a stem rests against moist soil.

What aerial roots are telling you about your plant's needs

Aerial roots are data. Here's how to read them.

**Active growth with bright green root tips** — on orchids especially — signals that the plant is healthy and actively taking up water. This is a good sign. Dull, silvery-white roots that look flat and papery are dry but still alive; shriveled, brown, or mushy roots are a problem. You can learn more about reading root condition in our guide to [how-to-read-houseplant-root-health].

**Lots of aerial roots on a climber, combined with leggy growth** — on a pothos or philodendron — can hint that the plant is reaching for more light or support. If a vine is producing long internodes with small leaves and multiple aerial roots at each node, consider whether it needs a moss pole to climb or brighter indirect light. Check out [how-to-create-a-moss-pole-for-climbing-houseplants] for practical setup guidance.

**Aerial roots that look dry and shriveled (aerial root desiccation)** — particularly in orchids and monsteras — often indicate that the ambient humidity is too low. Indoor air, especially in winter with heating running, is frequently drier than these tropical plants prefer. If you're noticing consistently desiccated aerial roots alongside brown leaf tips or curling leaves, improving humidity is the right response. See our post on [when-houseplants-need-a-humidity-boost] for approaches that actually work.

**Aerial roots pushing toward soil or water** — especially visible when a long pothos vine drapes near the pot's edge — shows the plant is trying to establish additional anchor points and nutrient access. You can guide these roots into the soil if you'd like, or simply let them be.

**Aerial roots in great numbers on a monstera** that has been in the same pot for a long time might coincide with the plant being somewhat rootbound below the soil — though the aerial roots themselves aren't proof of that. Check whether roots are circling the drainage holes or pushing out the top of the soil. Our guide to [how-to-identify-and-treat-root-bound-houseplants] covers what to look for.

Should you remove aerial roots — and how to do it safely

The short answer for most plants: you don't need to, and often shouldn't. Aerial roots are functional tissue. Removing them doesn't hurt the plant in most cases, but it doesn't help either — and for orchids, unnecessary removal can genuinely damage the plant's ability to absorb water.

**When it's perfectly fine to trim:** On climbing aroids — monstera, pothos, philodendron — you can snip aerial roots that are becoming unwieldy, catching on furniture, or simply bothering you aesthetically. Use clean, sharp scissors or pruning shears. Cut close to the node but avoid digging into the stem tissue itself. The plant will not be harmed. If you prefer to avoid trimming, you can tuck shorter aerial roots gently into the pot's soil, where they may establish and provide an additional uptake pathway.

**When to leave them alone:** Orchid aerial roots should never be removed from a healthy plant. Cutting them reduces the plant's capacity to absorb moisture and can introduce infection at the cut site. If a root is completely dead — brown, hollow, and shriveled all the way to the base — you can remove it cleanly with sterilized scissors, but leave any root that has any green or silver-white tissue. For staghorn ferns, aerial roots are the entire anchoring system and should not be disturbed.

**When to address the underlying environment instead:** If aerial roots on your orchid or monstera look persistently dry and papery, the more useful intervention is improving humidity or adjusting your watering approach — not trimming the roots away. Shriveled aerial roots are a symptom, not the problem itself.

**Tool hygiene matters:** Always use clean, sterilized cutting tools when trimming any plant tissue to avoid introducing pathogens at the wound site. A quick wipe with isopropyl alcohol before cutting is all it takes. See [how-to-clean-and-sterilize-pruning-tools-for-houseplants] for the full process.

**Propagation opportunity:** If you're trimming aerial roots on a pothos, philodendron, or monstera anyway, those stem sections with visible aerial roots (and a node) are your best candidates for propagation. The presence of an aerial root means root initiation is already underway, which makes water or soil propagation faster. See [how-to-propagate-plants-in-water] or [stem-cutting-propagation] for guidance.

Redirecting and using aerial roots to your advantage

Rather than trimming aerial roots, many plant owners find it more satisfying — and better for the plant — to put them to work.

**Guide them into a moss pole.** Monsteras and climbing philodendrons thrive when their aerial roots can grip a moist moss pole or coco coir totem. The roots will attach and, over time, help the plant climb upward naturally, producing larger leaves with more fenestrations (the holes monstera is famous for). Keep the moss pole slightly moist and the roots will do the rest. Our guide on [how-to-create-a-moss-pole-for-climbing-houseplants] walks through this in detail.

**Direct them into the soil or water.** A long pothos or philodendron vine with aerial roots dangling near the pot's edge can simply be looped back and the root end pressed gently into the soil. This gives the plant an extra uptake point and helps the plant look fuller. Alternatively, let the rooted cutting drop into a glass of water beside the pot for a charming — and functional — display.

**Use them as propagation nodes.** When you do prune a climbing plant for shape, prioritize stem sections that already have aerial roots visible at the node. These sections root faster and with greater reliability than bare-node cuttings.

**For orchids, give roots room.** If you're repotting a phalaenopsis, choose a pot that allows some roots to rest naturally above the medium or drape over the sides. Attempting to bury all roots in bark typically leads to rot. A clear plastic orchid pot is useful precisely because you can monitor root color and health through the sides.
