How to keep sphagnum moss alive: practical tips

Sphagnum moss is a plant belonging to the family of mosses that grows in peat bogs in specific locations around the world. It is sometimes transplanted for various reasons, including sale, repotting, and changes in environment. But how do you keep it alive during this process? This is what our editorial team will address in a few points.

What is sphagnum moss?

Sphagnum moss is a plant belonging to the moss family that grows in hydrophilic environments . There are various species of sphagnum, playing a vital role in the formation of peat bogs. However, they are primarily found in peatland areas distributed throughout the Northern Hemisphere.

These plants originate from peat bogs, which are areas of soil saturated with slightly acidic rainwater . This stagnant rainwater fosters biodiversity, and the bog must be located near a watercourse to maintain sufficient moisture. Sphagnum mosses are a valuable resource in gardening, but their harvesting is limited due to their slow growth and environmental restrictions.

Sphagnum moss plants are recognizable by their size, ranging from 10 to 20 cm, giving them a shrub-like appearance. They are composed of two parts, described as living and dead . The former is the upper part and the latter the lower part.

The upper part is where sphagnum moss grows, recognizable by its green appearance. This part includes leaves that curl in a spiral. The lower part is black and composed almost entirely of soil and decomposing plant matter rich in humus .

It should be noted that the upper part of the plant , where the moss grows, can be yellow, brown, white, or red depending on the season. Therefore, a brown color does not necessarily mean the plant is dead.

Given its properties and benefits for plants, farmers and agricultural entrepreneurs use it to improve their production . Therefore, it needs to be transported from its natural state, far from cities, to cultivated areas. How then can this be done?

Properties and uses of sphagnum moss

Sphagnum moss, this bog plant with shallow roots, possesses exceptional properties that make it invaluable for gardening and houseplants. Thanks to its impressive absorption capacity, it can retain up to 20 times its weight in water, making it an ideal substrate for plants requiring a humid environment. Furthermore, sphagnum moss is naturally acidifying, making it perfect for plants that prefer acidic soil. In addition, it is rich in polysaccharides, giving sphagnum moss valuable antibacterial properties to combat plant diseases. Whether for your orchids, carnivorous plants, or living walls, sphagnum moss will meet your substrate needs.

How to cultivate sphagnum moss?

To remove it from its original growing conditions , simply harvest it, taking care to preserve the living part by incorporating the dead part. Peat plays a vital role in the formation of peat bogs and is used as a component of horticultural substrates, as it retains moisture and can be incorporated into various gardening mixes. However, this method is recommended for experienced growers . Even they must have certain safety precautions for this type of transplanting.

Transplantation method by experts

It's important to know that only experts are authorized to collect Sphagnum moss from its natural environment . These plants are generally protected and subject to regulations that experts will try to follow in order to obtain the necessary permits.

In practice, they make incisions at the root and then in another part of the peat bog, placing the seedlings in a container. This container must be kept at a temperature similar to the natural environment . They then place them in a greenhouse where they cultivate them themselves. To return a purchased product, it is essential to keep it in its original condition. The steps include requesting a return, packaging the product, and shipping it according to the specified conditions. Some exceptions may apply; always check the return policy.

This involves chopping up live sphagnum moss and transplanting it into different pots for soilless cultivation or in a terrarium.

Amateur cultivation method

Amateurs can take a sphagnum moss culture , chop it, and divide it among several pots. Once the waiting period is over, you will have a double of sphagnum moss using the greenhouse method.

Simply cut the live sphagnum moss , water it, and place the substrate in the pots. Then spread it out in a mat-like shape and leave it in full sun in a humid environment . Kokedama, a style of Japanese bonsai where a plant's roots are wrapped in a ball of substrate and moss, uses sphagnum moss for its ability to retain moisture and promote plant growth.

Before learning how to care for sphagnum moss , it makes sense to know its advantages.

The benefits of sphagnum moss for carnivorous plants

It's important to know that sphagnum moss offers four key benefits for carnivorous plants . However, it's crucial to understand that these benefits are provided by the moss itself. Essentially, it offers water retention and drainage, increased resistance to external factors , and improved pH and fertility. Carnivorous plants require a substrate that retains moisture while allowing for adequate air circulation, and sphagnum moss perfectly meets these needs.

Water retention and drainage of sphagnum moss

One of the properties of sphagnum moss is that it retains water in its visible, green upper part. This keeps the soil or growing surface sufficiently moist for carnivorous plants to thrive.

Furthermore, this plant helps to drain the soil by aerating its roots and moss . And a plant in aerated soil can quickly access nutrients in addition to those provided by the living sphagnum moss .

Resistance to external agents

Just because we're talking about carnivorous plants does n't mean they're immune to external threats. But fortunately, live sphagnum moss has increased resistance due to its initial growth in peat bogs . In this case, you'll have a healthy carnivorous plant, free of fungi, insects, and other pests .

A pH adjustment

It's important to know that carnivorous plants like sundews, pitcher plants, and others mostly thrive in acidic environments . Since the formation of the peat bog has made the sphagnum moss acidophilic, it is colonizing its new surroundings.

It then distributes the pH to 3.5 or 4.5 depending on the surface area , which is suitable for carnivorous plants like those mentioned above. However, it's important to know that adding other substrates is recommended for a lasting and guaranteed effect.

Soil fertility through sphagnum moss

This advantage stems from its drainage, moisture retention , and soil aeration. Furthermore, it is known for its longevity, providing a continuous supply of nutrients to the soil and resulting in significant fertilization.

But these benefits will be useless if you don't know how to take proper care of them.

Using sphagnum moss in terrariums

Sphagnum moss is an ideal substrate choice for terrariums, thanks to its ability to retain moisture while remaining aerated. It creates a perfect environment for plants that require a humid atmosphere, such as orchids and carnivorous plants. Its lightness and ease of handling make it a material of choice for terrariums. For optimal results, it is recommended to combine sphagnum moss with other substrates such as coconut coir and coconut husk. This mixture helps create a balanced environment conducive to plant growth in a terrarium.

Sphagnum moss maintenance

It's true that sphagnum moss and the plant itself can change color; however, their greenish appearance is a sign of good health. Therefore, for optimal care, once you've opened the package, you should begin transplanting .

Here are some essential steps for its maintenance:

• Irrigation (it is important that it is filled with enough water. You will notice this when it no longer retains water).

• Shade (it is advisable not to put sphagnum moss in direct sunlight for a long period, as this will dehydrate the plant).

• Always prune (trim the longest ones, put everything in a new jar so that your carnivorous plant does not become invasive).

Don't forget to maintain the humidity and temperature indicated on the instructions provided by the Sphagnum moss supplier. You can also buy it online or in garden centers!

Benefits of sphagnum moss for the environment

Sphagnum moss is a sustainable and renewable resource, ideal for soil production. It can be cultivated sustainably, making it an eco-friendly choice for environmentally conscious gardeners. Its high water retention capacity reduces irrigation needs in gardens and crops, contributing to more efficient water management. Enriched with nutrients, sphagnum moss also improves soil fertility. Finally, by absorbing CO2 from the atmosphere, sphagnum moss plays a role in reducing greenhouse gas emissions, thus contributing to the fight against climate change. Using sphagnum moss in your crops and gardens is a way to help the environment while meeting the needs of your plants.
