Sphagnum moss is a popular growing medium for orchids due to its high water-holding capacity and good drainage properties. It can hold up to 20 times its weight in water, making it an excellent medium for orchids that require high humidity levels. The moisture-absorbing qualities of sphagnum moss ensure a healthy environment for orchids.
Sphagnum moss is suitable for epiphytic and epiphytic orchids due to its air-filled porosity, which ranges from 15 to 26, comparable to bark and greater than peat moss. It thrives in dry climates like California and Arizona, as it provides humidity. Sphagnum moss is suitable for phalaenopsis orchids, but should be repotted as a new pot.
Sphagnum can be used as an orchid potting medium, as it contains most imported phalaenopsis plants. It is a fine substrate and can hold water better than bark, making it an excellent potting material for young orchids. However, it is important to be cautious of parasites that can be transferred to orchids.
Live Sphagnum moss is a magic substance, as potting an ailing orchid in live moss can bring it back to health. However, it is crucial to use it correctly to avoid potential issues with the moss.
📹 Repotting Orchids in sphagnum moss ONLY (the RIGHT way) 👍
I love sphagnum moss and I think it loves me back :)) Here is how I pot my orchids in sphagnum moss, the right, safe way! 00:00 …
Is there a difference between orchid moss and sphagnum moss?
The recommended sphagnum moss for orchids is AAA New Zealand Sphagnum Moss or 5 Star Chilean Sphagnum Moss, which are both of similar quality but have a fluffier texture. The lesser grades of sphagnum are often labeled as “moss for orchids”, “organic moss”, or simply “sphagnum moss”. It’s important to distinguish between sphagnum moss and sphagnum peat moss, which is the dead moss that falls to the bottom of a sphagnum bog.
The top layer of live sphagnum moss is harvested first, followed by the bottom layer of peat moss. Peat moss is processed into a soil amendment used with orchids but has a different appearance and texture. Most sphagnum moss and peat moss found in nurseries and stores comes from Canada.
How often should I repot orchids in sphagnum moss?
Orchids should be repotted when new, every year or two, or when crowded roots push up and out of the pot. Spring is the best time to examine each plant for repotting, as it signals emergence from the dormant cycle. Holiday gift orchids or newly-purchased plants with sphagnum moss, which absorbs and holds water, create prime conditions for orchid root rot. Repot all new orchids as soon as they’re done blooming.
How do you water orchids in sphagnum moss?
To water an orchid, run the entire pot under the faucet until it flows freely through the drainage holes. If the orchid is potted in bark, let it soak in water for 10 minutes before draining and placing it back in its location. Orchids don’t need much water, but three ice cubes (about 1/4 cup) are sufficient. The duration between waterings depends on the amount of sun and the orchid species. Orchids can be watered from the top or bottom, with the top watering at the base and the bottom checking for under- or over-saturation of the potting medium.
Can I use sphagnum moss for orchids?
Orchids, epiphytes, are cultivated on tree branches and are typically grown in pots containing sphagnum moss or bark, which facilitates the care and maintenance of the plants. Commercial growers utilize sphagnum moss to prevent plant desiccation during the shipping and retail display processes. However, it is not a suitable medium for long-term growth due to its moisture-holding properties around the roots, which can lead to root rot if not maintained consistently.
Can I touch sphagnum moss?
Florists and gardeners should wear gloves and heavy clothing to avoid puncture wounds or scrapes that may allow fungal transmission. Gardeners and hobbyists using sphagnum moss for baskets or craft projects should also follow these guidelines. Wearing gloves and long sleeves prevents contact with the dried moss. The only time contracting the fungal organism is when in direct contact with the moss and there is an opening in the skin for the fungus to enter. Consult a physician for further questions about sporotrichosis fungus.
What is the best thing to repot orchids in?
In order to repot an orchid, it is necessary to transfer the plant to a larger pot and add a new orchid potting mix. The potting mixture should be specifically formulated for orchids and should contain sphagnum moss, fir bark, coconut husk, and tree fern fibers. Once the orchid has been repotted, return it to its original location and resume the usual watering regimen.
Can plants stay in sphagnum moss?
Sphagnum moss is a versatile and easy-to-use growing medium for herbaceous houseplants. It is a simple and easier alternative to soil, making it suitable for most herbaceous houseplants. Sphagnum moss is best paired with clear pots, as it makes it easier to see when the moss is drying out. To repot plants, surround the root system with the moss and lightly compact it down. After potting, soak the moss with water and gently squeeze the pot to remove excess.
Sphagnum moss can retain more water than soil, reducing the need for watering and increasing ambient humidity around the plant. It is less likely to develop pests and can be a great alternative in higher humidity environments. If the plant is kept in the same pot for extended periods, the moss will outperform the soil and last longer before needing replenishment. Using moss as a top dressing provides the same benefits as planting in moss without some drawbacks.
Can plants grow in just sphagnum moss?

How do you sterilize sphagnum moss for orchids?
To prepare a Sphagnum for horticulture, place a small amount in a glass bowl, pre-soak it in distilled water, and then add enough water to cover the Sphagnum. Cover the bowl with plastic wrap and microwave on full power until the water boils, then continue boiling for two minutes. Open the microwave door to vent moisture buildup, leave the bowl in the microwave for about one minute, and remove the bowl from the microwave.
Carefully pull back the plastic wrap, stir the Sphagnum, and microwave on full power for at least five minutes. Remove the bowl, place it on a sturdy, level, heat-safe surface, and leave the plastic wrap in place to sterilize the steam.
When safe to handle, squeeze excess water out of the Sphagnum and place it in a sterile plastic bag. Reintroducing beneficial organisms like bacteria, insects, and microfauna can help maintain ecosystem health in horticulture and terrariums. Mixing substrate from an existing grow bin or container and adding microfauna such as isopods and springtails can also help. If adding substrate from an existing setup, ensure the source material doesn’t have pests or disease.
Optimizing the use of sterile Sphagnum by filling plant pots with half non-sterile Sphagnum at the bottom and only using sterile Sphagnum for the top half can suppress any Sphagnum spores from germinating, saving time and energy.
What plants don’t like sphagnum moss?
Sphagnum moss, a type of potting media, has an acidic root zone that can negatively impact certain plant species from alkaline habitats. These plants are not adapted to tolerate acidic conditions, as their natural conditions are never acidic. This affects the availability of nutrients and can lead to issues like nutrient toxicity for micro nutrients and/or nutrient deficiency of macro nutrients.
Oyster shells can be added to potting media to prevent acidification, but it is not recommended for all plants, as most plants are not from alkaline habitats and are not adapted to alkaline conditions. Many tropical plants do need some amount of acidity.
As the moss ages, it becomes anaerobic, which limits airflow and creates an environment for fermentation. This is similar to how sauerkraut is made under anaerobic conditions, where bacteria and fungi use up available oxygen. This can cause root rot from overwatering and other problems.
To avoid both 1 and 2, repotting more often than regular potting media is necessary when using sphagnum moss. It is also challenging to remove old media, especially on rooty plants like Alocasias, Begonias, or Philodendrons.
Sphagnum moss still has value for growers, but it is important to be aware of potential issues and changes in the roots’ condition. Early success may not represent the full cycle of the media, and it is crucial to be aware of what to watch for, avoid, or do if a plant has been in sphagnum for over a year.
Can I use sphagnum moss instead of potting soil?
Sphagnum moss can be used alone or mixed with soil or other potting mediums. It requires frequent watering and fertilizers due to its low nutrient content. It is popular for lining hanging baskets and creating shapes in succulent wreaths or floral displays. Sphagnum moss is also decorative when used in container planting, enhancing the finished look of pots, baskets, or terrariums and filling in dead space. Its soft, light, and pliable form makes it a versatile and practical choice for various plant care needs.
📹 Why I stopped growing my orchids in live sphagnum moss
… way i grow my orchids and uh it’s kind of simple um trying to maintain a collection of almost 200 plants and live sphagnum moss …
Do you still use the zero water? Which ones are in the semi water culture? Any changes since you made this article? How long can they go without watering? So far, mine can go a week except for a few mounted ones. Trying to find a way to stretch to 2 weeks on occasion. Great to see your article! Been a long time. Happy growing!
You have a beautiful orchid collection! I was about to suggest to you that you need your own website, and here you are! Just so you know, I don’t water my sprouted sphagnum that I showed in the last article more often than I do the regular, unsprouted sphagnum. It’s weird, a couple of years ago I had problems with algae growing in my moss pots, but I don’t anymore. I think larger pots tend to grow algae more than smaller pots do…that’s the only thing I can figure. Anyway, just wanted to let you know I enjoyed your article and the skunk named Stella is beautiful!
Thanks so much for the update!!! I found myself more fascinated with the skunk…is that your pet? Your orchids look great too, but that skunk was something else ha!ha! I find that my Oncidium types for me grow better in water culture but I live in a dry climate in Canada, and it helps with not getting the accordion shaped leaves. Thanks again for the update. I’m growing some live moss since I was impressed with your older articles. May I ask what your water source is now since you moved? Do you use reverse osmosis or still zero water pitcher, or find your new water source okay? Thanks again.
