From oak trees to succulents, roots are a crucial component of all plants. Although there are many different types of roots and some that are specialized, all roots assist their plants in the following crucial ways:
- Roots absorb moisture and disperse it throughout the plant.
- Nutrients are absorbed by roots, which then distribute them throughout the plant.
- Roots hold plants firmly in place, usually in soil.
These functions are often carried out by roots, which develop at the base of plants and reside in the soil. When the plant’s underground roots are unable to adequately meet its needs for water or a stable base, stem roots will eventually form. When you observe a succulent forming aerial roots from the stem, it is doing so to meet a need. Aerial roots on succulents are typically a sign that the plant needs more moisture or anchor points.
What Do Aerial Roots Do?
Airborne roots have the capacity to capture water vapor from the atmosphere and transfer it to the rest of the plant. This increases the soil’s moisture supply. (Some plants, like mangroves, that are adapted to grow in marshy or extremely moist environments actually use aerial roots for the reverse process to aid in plant respiration. Before aerial roots could form, succulents are likely to perish in such moist environments.)
In several different ways, aerial roots support plants as well. In the case of vines like ivy, they may climb a structure, or they may help ground cover plants proliferate by creating new rooting sites. On succulents, aerial roots often develop where a component of the plant is likely to fall, either as a result of damage or evolution. The plant will sprout aerial roots in preparation for coming into touch with the dirt if it is damaged or etiolates from lack of light. When this happens, the aerial roots will be able to root into the soil, absorbing water and nutrients while serving as an anchor for that area of the succulent.
The plantlets of Kalanchoe houghtonii can be seen in the image above, each of which has a spray of aerial roots growing on the little stem connecting it to the mother plant’s leaf. These little stems will eventually dry out and snap, causing the young plants to fall to the ground. When that time comes, their aerial roots will be prepared to plant themselves firmly in the ground and produce a new generation of Kalanchoe. In this instance, the aerial roots on the succulent are prepared to support the new plantlets when a portion of the plant drops.
What Aerial Roots on Succulents Mean
Succulents with aerial roots indicate the plant is attempting to fill a need. Sometimes the plant’s needs are satisfied by the roots that are sprouting from the stem. However, you should always make an effort to spot these changes in your plants and figure out what they signify. To maintain the succulent’s health and vitality, you might decide to alter your care practices.
Sedum rubrotinctum “Aurora” needs water. Observe how a few of the leaves have a slight wrinkle to them. The succulent requires more water as evidenced by this. The leaves are lovely and full overall. I doubt that I would have seen the early puckering indications. But in response, the plant is growing aerial roots to increase its water intake. That is a definite indication that the plant requires a little extra water. To guide your succulent care, keep an eye out for signals like this. Just be careful not to overreact and give it too much water.
It might be challenging to determine whether a succulent is reaching for more light or whether that is simply how it grows. If it grows aerial roots along the stem, it obviously requires extra support and may be preparing for that part of the plant to fall to the ground. Etiolation is severe; don’t wait for these roots to emerge before taking action. Aerial roots, though, might occasionally shed light on the situation.
Aerial Roots on Succulents
This Kalanchoe tomentosa Silver Panda is flourishing inside in good condition. The aerial roots show that it needs a little bit more water. The succulent’s leaves are large and firm, and all other signs point to a healthy plant. You could slightly increase the watering frequency while maintaining the same amount for the plant. However, it’s likely that this succulent’s requirement for additional water has been met by the roots that are emerging from the stem.
Aerial Roots Looking for Support
This kalanchoe is expanding swiftly and has started to etiolate a little. When a plant grows very large and reaches out for more light, it is said to be etiolated (EE-tee-oh-lated). This stem is forming aerial roots as it bends down and over to create anchor points when it reaches the soil. The best course of action for this one would be to cut back the stem and let it to root independently in a different soil-filled pot. This is how stem cutting propagation works at its core. This stem would soon create an active plant on its own thanks to its extensive aerial roots.
What to Do with Aerial Roots
Succulents’ aerial roots are a crucial sign of the health of the plant. Understanding this will help you maintain the health of your succulents. Feel free to cut or trim back aerial roots from succulents that are growing roots from the stem after you have recognized and taken care of the necessity that led to the roots’ development. However, don’t just brush them off as irrelevant and get rid of them without first looking at the underlying problems. For a reason, the succulent invested time, effort, and resources in growing those roots.
This Sedum rubrotinctum ‘Mini Me’ is not a true hanging succulent; rather, it is a low-growing ground cover plant. Longer stems generate aerial roots as they look for a place to spread out on the earth. The plant will only grow new roots even if these ones are cut down. To create numerous other plants, the stems can be pruned and rooted in soil.
Succulents’ aerial roots indicate that the plant requires something that its normal root system cannot give. This is a favorable review of your care. The message these roots deliver is the same regardless of whether types generate them more frequently.

Can aerial roots help succulents grow?
If you’ve cultivated or owned succulents for a while, you’ve probably seen that eventually, some of them start to produce roots that emerge from the stem. Although not dangerous, these are known as aerial roots, and they are a blatant indication that your succulent requires care.
Can aerial roots be planted?
An excellent example of roots you can plant is the aerial roots on houseplants. One of the most well-known examples of this can be seen on spider plants. Spider plants are frequently cultivated in hanging baskets, where they produce plantlets that dangle from peculiar, wiry stems that extend from the plant. There are numerous aerial roots on each plantlet. By cutting off the plantlets and placing them with their roots buried in the soil, you can propagate the plant.
Windowleaf plants are indoor plants that utilize aerial roots in a special way. Windowleaf vines climb trees in their natural environment, reaching high into the canopy of the rainforest. Aerial roots are produced, which spread outward until they touch the ground. The strong stems are held in place by the stiff roots, which serve as guy wires. These plants can be multiplied by cutting off a piece of stem just below an aerial root and planting it in a pot.
Some aerial root plants cannot be planted in soil. Epiphytes are plants that use the structural support of other plants to grow on them. The purpose of their aerial roots is to remain above ground, where they can collect nutrients from the air, surface water, and debris. An illustration of this kind of plant would be epiphytic orchids. When to water your epiphytic orchids depends on the color of the aerial roots. Aerial roots with little moisture are silvery gray in appearance, whereas those with lots of moisture have a green tint.
Aerial roots can develop into earth roots.
You can, indeed. The roots will continue to expand in the soil as a result and will have a function to absorb water and nutrients. Due to the lack of rain indoors, they are unable to absorb moisture when hung in the air, therefore they serve little purpose unless you periodically water or mist them.
Why do the roots on my succulent grow vertically?
A succulent that isn’t getting enough water and frequently when it’s in a humid climate will typically develop aerial roots. Through their roots, succulents take up water from the air around them.
Soil with big particles is crucial for the health of your succulent because of this.
Your succulent may not be getting enough water if you aren’t watering it properly, in which case it will begin to “seek for more.” At this point, aerial roots begin to develop.
Observe how the bottom of these Crassula rupestris is quite dried up and how many fresh air roots have sprouted.
The lack of sunlight has also caused this plant to become very languid. A succulent might occasionally send out air roots if it isn’t getting enough sunshine.
A succulent is more likely to produce aerial roots when it begins to spread out, though this isn’t always the case.
How do I handle succulent offshoots?
It’s crucial to understand that young plants won’t be harmed or affected by them, particularly those that develop near the mother plant’s base.
Although the offsets may appear cramped or unpleasant, they are precisely where they should be.
Have faith in Mother Nature’s processes. They have been engaged in this activity for a lot longer than we have.
Be Patient
I advise delaying their removal until the offsets are roughly half the size of the main plant. This guarantees that your infants receive the right nutrition and have the best chance of surviving on their own.
What’s Next?
Once your succulents begin to produce offsets, you might want to repot them in a little bigger container to provide room for the hen and the baby chicks.
With a pair of pruners, you can remove the offsets once they have grown to half the size of the mother plant.
Watch for the wound to callus. Put them in a shady, light area on top of fresh soil, don’t water them, and ignore them.
They will eventually take root in the ground, and then presto! You were successful in creating one to eight new playable plants.
How should I use succulent roots?
What is there to love other than a succulent? Obviously, a full garden of succulents! Fortunately for us, it’s simple to propagate a variety of these resilient, vibrant plants at home. We can’t wait to see succulents growing all year long in containers around the house and garden; there are various easy ways to reproduce them.
Propagating by Division: Plants that have gotten too leggy perform best with this method, which produces new succulents from cuttings. Start by delicately removing any leaves that may be attached to the stem below the rosette; be sure to preserve the leaf’s base while you do so. After all the leaves have been eliminated, cut the rosette with shears, leaving a brief stem intact. The cuttings should be let to dry in an empty tray for a few days until the raw ends have calloused. The cuttings can then be rooted in either water or soil.
Soil: After the stems have calloused, set the cuttings on top of a shallow tray filled with well-draining cactus/succulent soil. From the base of the cuttings, roots and little plants will start to emerge in a few weeks. Once the roots start to show, water sparingly once a week; take care not to overwater. The parent leaf will eventually wither; carefully remove it while taking care not to harm the young roots. Your propagated succulents can be replanted once they have established roots. As soon as the plants are established, keep them out of direct sunlight.
Water: After the stem has calloused, place a cutting with the end barely visible above the water’s surface on the lip of a glass or jar filled with water. Pick a sunny location for your glass. The incision will eventually produce roots that extend toward the water. Once roots have sprouted, your new succulent can either be replanted in succulent potting soil or allowed to remain submerged in water as illustrated above.
Offsets are little plants that develop at the base of the main specimen, and many species of succulents, such as aloe, hens and chicks, and some cacti, will generate them. Check for root growth after an offset has developed for two to three weeks before carefully twisting, cutting, or using a sharp knife to separate it from the main stem. Be cautious to prevent destroying any already-formed roots. Follow the directions above for propagating in soil or water, letting the offsets dry, establish roots, and then repot when they have had time to callus any exposed regions. Removing offsets has the added benefit of enhancing the health of your current succulents and redirecting energy into the growth of the primary plant.
Do I need to bury aerial roots?
Because they take in moisture and carbon dioxide, aerial roots on orchids are essential to the plant’s ability to develop healthy roots, leaves, and flowers. Even if the roots appear to be dead, this is true. The best course of action is to ignore the air roots.
Extensive aerial roots may indicate that your orchid is overgrown and requires a larger pot. Lower aerial roots can now be buried in the new container. Avoid forcing the roots since they can break if you do.
Can aerial roots be submerged in water?
I’ve seen several sources advise you to put a bowl of water in the planter for your Monster deliciosa and trail its aerial roots in there. According to the theory, this is because aerial roots may actually absorb moisture. However, submerging them in water nonstop won’t likely accomplish much more than cause them to deteriorate and perhaps put your plant in risk.
However, you can frequently spray the aerial roots of your Monstera. Again, there is no scientific evidence that this makes a significant difference, but it won’t hurt. In addition, since these tropical plants prefer their surroundings to be moist, make sure the air humidity is not too low.
