The most attractive aspects of the orchid hobby are its versatility and potential for experimentation. Mounting your orchids on various types of substrates to recreate the aura of their natural habitat can be one of the most exciting parts of this hobby. Cork bark commands a premium place among the various types of mounts, not only due to its interesting rugged texture, but also due to its lightness, strength and long life when compared to other types of wood mounts.
While it’s no mean feat to mount your orchid on cork bark, knowing about this medium, using the right material for mounting, and its correct maintenance thereafter, will help you get the most out of this coveted material. So get set to provide your prized collection a boost in terms of aesthetics and fuss-free growing. And last, but not the least, give vent to your creativity and display your orchids in the best possible way, even when not in bloom. The effect is sheer magic. The satisfaction – guaranteed.
About cork bark
While cork is known for its rugged attractiveness, it is the cost that is a major deterrent for orchid hobbyists.
50% of the global cork production comes from Portugal, accounting for nearly 70% of world trade. The bark is obtained from the Quercus suber or cork oak trees. The trees are slow-growing, with a lifespan of 200 years, and are ready for harvesting once they mature. Interestingly, the bark is carefully removed without harming the tree. The tree grows back the bark over a period of ten years before it is ready for harvesting again. The slow growth and a gap of 10 years make cork a costly material. A heavy import duty of 29.8% further makes cork expensive, which is why it commands a premium price.
Price notwithstanding, as you become an experienced grower, you will inevitably begin experimenting with different types of media and substrates, and ultimately consider cork or even driftwood for mounting orchids. The satisfaction of growing and blooming orchids as they would in nature, is unmatched, which is why seasoned orchid hobbyists take great pride in their collection of cork mounted orchids. You have to only look at the Instagram posts of ‘Romain Orchids’ or the You tube channel of ‘Roger’s Orchids’, to understand why mounting orchids on cork or drift wood can take your display to the next level.

The Upside of cork mounts
While cork is attractive in a wild, natural way, what makes it a preferred material for mounting orchids is its rough texture with crevices, bumps and holes, which provide orchid roots the perfect grip to attach themselves firmly. The medium is water resistant and does not absorb water or become soggy, due to which it does not rot easily. Of course, if it is maintained soaking wet for prolonged periods without drying up in between, then rot and fungal infections do set in and weaken the bark.
Cork is seen as good value for money since it is long-lasting and can be reused if your orchid outgrows its mount after several years. All you have to do is to remove the orchid carefully without damaging its roots, and mount it on a bigger one. The old mount can then be sterilized and reused for mounting other orchids.
Since mounts are hung vertically, you also end up saving a lot of space. This way, you can grow your collection comfortably without space constraints. Moreover, you can save up on expensive media, pots, and planters, which require frequent repotting, especially if you use organic medium that breaks down periodically.
Most important of all, since your orchid is hanging vertically with minimal medium, and has a good wet-dry cycle, the quick drying ensures that the risk of development of rot disease is minimalized to a great extent.
And the downside
The downside is that orchid mounts tend to dry out rather quickly, unlike their potted counterparts. So you need to mount the orchids that tend to thrive in a quick wet-dry cycle. This means that you will be watering your mounts every day, sometimes even twice a day, depending on how quickly they dry out. As a beginner, a quick way to gauge this would be to be on the lookout for signs of dehydration. Accordingly, you can adjust your watering routine.
Daily watering could be a daunting proposition, especially if you are preoccupied with work, among other things. Fitting this into your busy schedule could turn it into a cumbersome task. Yet, orchid hobbyists are drawn to mounted orchids because of the sheer beauty of this natural display. To be able to recreate this near natural environment within your grow space and enjoy the resultant effect, makes all the effort worthwhile.
But it’s not as bad as you think. There are a number of ways you can make your watering routine less tedious. Investing in a good water spray will get your watering done in very little time. Some orchid hobbyists add a little bit of extra moss (loosely packed) and this keeps the humidity levels reasonably suitable for the orchid’s healthy growth. If you are using minimal amount of moss, then light spritzing of the mount with a mister later during the day also helps in maintaining good humidity levels.
What kind of orchids should you mount on cork bark
Orchid hobbyists are drawn to mounting their orchids due to the beautiful effect they create. The challenge of achieving the best possible effect is something that they deliberate on and choose their orchids with great care.
First and foremost on the checklist would be to pick an orchid that is hardy and can tolerate dry conditions reasonably well. Orchids such as Dendrobiums, Brassavola, Cattleya and species Phalaenopsis will do well on mounts. While Oncidiums need high humidity around their roots, you can grow them well on mounts too if you can provide them with good humidity by padding up with extra sphagnum moss. This can be done later once you gauge your orchid’s moisture requirements.
Second, would be to consider the aesthetics depending on the cork piece that you would be using. Larger orchids such as Brassavola, Cattleya and Phalaenopsis require larger bark pieces as compared to compact or miniature orchids. This is desired so that the bark forms a natural backdrop for your orchids, thereby enhancing their visual appeal significantly.
Third, miniature orchids have a charm of their own and their water requirement is minimal (a quick wet-dry cycle). So these orchids grow well on mounts. Tolumnia, Dendrobium aggregatum, Sophronitis cernua, Neofinetia falcata and Aerangis orchids, to name a few, look amazing on mounts. An added bonus is that they look great even when not in bloom. When in bloom, they appear very exotic and wild, like getting a slice of the woods into your grow space.
Cork mounted orchids require very little care, unlike potted orchids that require repotting and putting together a suitable potting mix.
The most important care requirement would be to water the mounts daily. If your mounted orchid has thick roots such as in the case of Phalaenopsis, give it a good soak for a few minutes or alternatively, hold it under running water for two minutes. The velamen turns green when the water gets absorbed. After a few minutes, again soak the orchid for a few minutes. This will ensure the roots get saturated with moisture. This, together with the damp moss will meet the orchid’s moisture requirement. You can fertilize your orchids in a similar way once a week for good results.
For your miniature and thin rooted orchids such as oncidium or Tolumnia, you can give it a good spritz with a sprayer. That will take care of its water requirements. Excessive watering or soaking in this case will lead to rot issues. Also take extra care to avoid water pooling up in the crown of your orchids as well as inside new growths or sheaths
A general rule to be followed while watering mounted orchids would be to avoid keeping the moss soaking wet for prolonged periods. Allowing it to dry out fully before watering it again will ensure that the cork does not disintegrate due to prolonged exposure to soaking wet conditions. Use minimal quantity of moss for mounting, depending on the orchid’s moisture requirement. If need be, you can always add more moss later, if the mounts dry up too fast.
Hang your mounted orchids in bright indirect light as it is important for blooming your mounted orchids. Direct morning or evening light can also be tolerated fairly well by these orchids. During summer, you will need to check on your orchids frequently and even move your mounts away from harsh summer daylight.
Fertilizing your orchids can be done either by soaking the mount for a few minutes or by spraying it. Do ensure that you do not share water between your mounts as bacterial and fungal diseases could spread to your healthy orchids. I prefer spraying the orchids and saturating their roots for a few minutes and repeating after a gap of few minutes.
I have always wanted to mount my orchids on cork bark, but since it is imported from Portugal, it is not easily available in India. Experimenting with different types of wood mounts brought in mixed results. Recently, I treated myself to some cork bark pieces paying a hefty price. I was excited when my package arrived.
I spent time on choosing the right type of orchids to match the cork mounts. For this project, I chose three orchids – Aerangis biloba, Neofinetia falcata and Sideria japonica. All the three are small type of orchids and create a beautiful effect when mounted.
I was excited and full of anticipation even as I mounted the orchids. When I was done, I was thrilled and very satisfied with the results. While the mounts were expensive, the joy it gives me every day more than makes up for it. I eagerly look forward to the day these orchids will bloom. It would indeed be a dream come true for me.

- Clean the cork bark by scrubbing it with liquid dish wash. Ensure that you rinse it off completely so that no residue remains. Allow it to dry off completely.
- Get your orchid ready for mounting by cleaning it up. Remove any dead roots and old potting medium completely by giving the root system a good rinse. Moistening the roots of the orchid will minimise damage to the roots. Dry roots are more susceptible to snapping, while moistening them will make them more pliable.
- Sterilize your work area by rubbing it with a surgical spirit swab.
- Place the bark on the work surface and check the positioning of the plant. Hold the plant and mount upright to get an idea of how it would look. Try a couple of ways and assess which one will give the desired result. Mounting your plants inverted will help prevent crown rot. Once you finalise the positioning, remove the plant and mark the place that you want to pass the wire hanger through.
- Use the metal drill to carefully drill a hole of the desired size. The bark is soft and needs to be handled carefully to avoid damage.
- Pass the wire hanger and press into a loop so that the mount is firmly held and does not flop from one side to the other.
- Now place the plant on the cork and place a small quantity of moss on the roots of the orchid. This will help in keeping the roots moist. Ensure that the moss is not too close to the stem of the orchid. The stem should not be buried in moss as it will read to stem rot.
- Holding the moss and plant in place, use fishing line or thin thread to fasten the orchid to the mount. Ensure that the moss is fluffy and not very compacted. This will ensure that the orchid roots get sufficient air to breathe. You can even add cleaned up natural moss patches from your neighbourhood to give it an interesting look. The moss will grow and spread on the mount, adding to its beauty.
- Wind the thread several times to ensure the orchid is held snugly in place.
- Tie double knots several times to prevent the unravelling of the mount. Cut off any excess thread to give it a neat appearance.
- Attach the label on the back side of the mount, mentioning name and date of mounting. This will help in keeping it concealed.
- Spritz water on the moss and hang it up in place. Avoid wetting the crown area while watering your orchid.
Mounting your orchids on cork bark raises the bar for orchid hobbyists. To be able to mimic nature’s unmatched beauty and bring it into your home is one of the most creatively satisfying experiences. The orchid hobby is supposed to be savoured and enjoyed. So if you have time at your disposal and the inclination to water your orchids every day, then go for it and enjoy looking after your cork mounted orchids. Your orchids will love it even more and will thrive in this new environment.
