What to Do With Orchid Roots: Care and Maintenance for Optimal Growth
What to Do With Orchid Roots?
When it comes to orchid roots, it is important to differentiate between roots that grow in potting media and aerial roots.
Aerial roots serve important functions such as aiding in photosynthesis, absorbing water and nutrients, and helping the orchid attach to its host.
It is not recommended to cut off healthy aerial roots.
However, if the aerial roots bother you, they can be trimmed gradually to allow the orchid to adjust.
On the other hand, potting media roots should be firm and white to green in color, indicating a healthy plant.
Rotted or brittle roots should be removed, and the remaining plant can be saved by anchoring it with chenille stems while it grows new roots.
Repotting is recommended when new roots begin to emerge.
Key Points:
- Differentiate between roots in potting media and aerial roots
- Aerial roots serve important functions for the orchid
- Healthy aerial roots should not be cut off
- Trimming can be done gradually to adjust the orchid
- Potting media roots should be firm and white to green in color
- Remove rotted or brittle roots and anchor the plant with chenille stems
Did You Know?
1. The roots of orchids have a unique ability to photosynthesize, producing energy through the process of photosynthesis just like leaves do. This adaptation allows them to absorb sunlight and receive nourishment even when lacking access to sufficient nutrients from their growing medium.
2. Orchid roots have a symbiotic relationship with fungi. They form a mutually beneficial partnership where the fungi help the roots absorb water, nutrients, and minerals from the growing medium, while the roots supply the fungi with sugars produced through photosynthesis. This relationship greatly enhances the survival and growth of orchids.
3. When orchid roots are exposed to air or dry conditions, they become grayish-white in color due to a specialized layer of cells called velamen. The velamen acts as a sponge, absorbing moisture from the air and providing protection to the delicate inner root tissues against desiccation.
4. Some orchid roots possess a specific adaptation called pneumatophores. These specialized roots grow upward above the ground to aid in gas exchange in swampy or waterlogged environments. Pneumatophores allow the roots to obtain oxygen directly, facilitating respiration in an otherwise oxygen-deprived area.
5. The aerial roots of orchids can sometimes develop into keikis, which are essentially baby orchid clones. Keikis can grow along the stem or emerge directly from the aerial roots, and once they have developed their own set of roots and leaves, they can be separated from the parent plant to grow as independent individuals. This natural method of vegetative propagation is often employed by orchid enthusiasts to expand their orchid collection.
Types Of Orchid Roots: Burrowing And Aerial
Orchid roots can be classified into two main types: burrowing roots and aerial roots.
-
Burrowing roots grow down into the potting media, seeking water and nutrients. They are covered with velamen, which acts like a sponge, absorbing water and protecting the root.
-
Aerial roots, on the other hand, do not grow down into the potting media. Instead, they extend outwards, searching for a tree branch to attach to. These roots are adapted to absorb moisture from the air.

“Orchids have two main types of roots: burrowing roots and aerial roots. Burrowing roots grow into the potting media to find water and nutrients, while aerial roots extend outward to find a tree branch to attach to. The burrowing roots are covered with velamen, which acts as a sponge to absorb water and protect the root. On the other hand, aerial roots have adapted to absorb moisture from the air.”
Recognizing Healthy And Unhealthy Orchid Roots
Healthy orchid roots are crucial for the overall well-being of the plant. It is important to know how to recognize healthy and unhealthy roots to ensure the proper care and maintenance of your orchid.
- Healthy roots are firm to the touch and have a white to green color. They indicate that the orchid is receiving sufficient water and nutrients.
- Bright green roots all the time can be a sign of overwatering, which can eventually lead to the death of the orchid.
- Rotted roots are brown, mushy, and hollow, usually caused by overwatering.
- Brittle roots indicate under-watering.
- It is important to remove dead roots and support the remaining plant using chenille stems while it grows new roots.
Importance And Functions Of Aerial Roots
Aerial roots are essential for the growth and survival of an orchid. They serve multiple crucial functions that contribute to the overall health of the plant. First, they play a role in photosynthesis by containing chlorophyll and generating energy for the orchid. Second, these roots absorb water and nutrients from the air, which is especially beneficial for epiphytic orchids that grow on other plants. Finally, aerial roots assist the orchid in attaching itself to its host, ensuring stability and support.
Proper Care For Aerial Roots
When it comes to caring for aerial roots, it is important to understand their unique physiology and needs. It is not recommended to cut off healthy aerial roots, as they serve important functions for the orchid. Instead, focus on maintaining their health and providing the optimal conditions for their growth. One way to do this is by properly watering your orchid. Rather than relying solely on the appearance of aerial roots, it is advised to check the dampness of the potting media. Mist the roots, increase humidity, or leave them as they are if they appear dried out. Remember, the thicker coating called velamen on aerial roots distinguishes them from the roots growing in the potting medium.
Trimming Air Roots: When And How
Trimming air roots should be done with caution and only when necessary. Cutting off healthy air roots is not recommended as it can disrupt the orchid’s overall health and survival. However, if you find that the air roots are getting out of hand or bothering you aesthetically, you can trim a few at a time to allow the orchid to adjust slowly. When trimming air roots, it is important to do so carefully, avoiding any harm to the rest of the plant. Trim brown and soft air roots, as they are likely damaged or dead. By following these trimming practices, you can maintain the health and aesthetics of your orchid without sacrificing its overall well-being.
Understanding the different types of orchid roots and their characteristics is crucial for their proper care and maintenance. Recognizing healthy and unhealthy roots allows for timely action to preserve the health of the orchid. Aerial roots, although sometimes misunderstood, serve important functions and should be cared for appropriately. By providing the optimal conditions for root growth and knowing when and how to trim air roots, orchid enthusiasts can ensure the optimal growth and beauty of their plants.

Frequently Asked Questions
Can you do anything with orchid roots?
Orchid roots, including aerial roots, have their own unique purposes and functions. While some may find them visually unappealing, healthy and firm aerial roots are actually beneficial for the plant. These roots play a crucial role in absorbing moisture and nutrients from the air, aiding the orchid in its overall growth and development. Therefore, if the aerial roots appear white and firm, it is recommended to leave them be as they are integral to the plant’s well-being. However, if any roots are discolored or soft, it is advisable to trim them delicately to prevent potential harm to the orchid, remembering to exercise caution not to cut too deep.
Should I bury the air roots on my orchid?
It is generally advised not to bury the air roots of an orchid. Aerial roots are naturally designed to grow outside the pot and burying them may lead to their decline, especially if the potting medium is compact. Unless the orchid lacks regular potted roots, it is recommended to let the aerial roots remain outside the pot.
What to do with dead orchid roots?
If your orchid has dead roots, it is generally best to leave them alone unless your orchid lacks a strong root system. In that case, you may want to consider trimming off partially-decayed roots. Additionally, if your orchid’s bloom stem is dry and lifeless, it is recommended to cut it off. By taking these measures, you can ensure that your orchid remains healthy and can focus its energy on growing new roots and producing beautiful blooms.
What can I do with bare root orchids?
Bare root orchids offer a myriad of opportunities for plant enthusiasts. Once your plant is in a healthy condition, you can utilize bare root orchids by mixing a small amount of plant food with water, as instructed by the manufacturer. Soaking your bare-rooted orchid in this solution for around 15 minutes before repotting can stimulate new root growth, which is essential for the plant’s overall health and vitality. With proper care and attention, bare root orchids can flourish into beautiful specimens, enhancing your indoor or outdoor space with their vibrant blooms.
