Have you ever successfully reproduced marimo naturally (without splitting them apart)?
If not, here are a few tips on how to encourage natural reproduction:
- Take one or more larger marimo and place them in a separate jar, aquarium, or other container.
- Let the marimo live undisturbed and change the water as little as possible to avoid disturbing the tiny new growths.
- It can be helpful to add a small aquarium filter to gently circulate the water and prevent deposits from forming on the surface (although this is not necessary). If you do, there is no need to change the water.
- Wait several weeks or even months for a tiny ball of algae to naturally break away from the larger marimo.
- Let the tiny ball grow naturally for several weeks or months. Once it has grown enough, you can gently roll it into a nice round shape, as shown in the picture.
- After one to two years, the new marimo can grow to around 1–2 cm in diameter.
This is the natural way marimo reproduce. We do not recommend other methods, especially splitting or tearing them apart.
More than 10 baby marimo can naturally break away from a single larger marimo over the course of a year. This means that in the wild, where many marimo grow together, their natural reproduction can be truly remarkable.
Our baby marimo production
As the only producer of marimo in the EU, we grow our own marimo from scratch. They are tiny, lovingly grown, and ready to spread joy wherever they go.
If you haven’t been successful at reproducing your marimo, or simply don’t want to wait for your baby marimo to grow, you can take advantage of our selection. The more baby marimo you order, the better the price.
Macro shots of naturally reproduced marimo
These detailed photographs show what marimo look like at approximately 4 months old. At this stage, they are just 3–5 mm in diameter.
Marimo grow faster during their early stages. However, the larger they become, the more slowly they grow.
