Making a Marimo moss ball terrarium is a fun and easy project that enables  bringing a little bit of nature inside. This DIY project yields a peaceful, low-maintenance terrarium that features five easy-to-grow aquatic plants.

DIY Moss Ball Terrarium

Materials Needed

  • Glass container: Use a jar, vase, or bottle as the base for the terrarium.
  • Substrate: Sand, gravel or small pebbles are required to form the base of the moss balls and decorations.
  • Decorative elements: Adding a couple of pieces of driftwood, shells, and even a few plants will help them look aesthetically pleasing and create a mini ecosystem.
  • Marimo moss balls: These are the main point of the terrarium, a thing of beauty and peace.

Step-by-Step Instructions

  1. The glass container  must be free from all dust and dirt. The best is to rinse with warm water and then let it fully dry before beginning the project.
  2. The bottom of the container should have a layer of sand, gravel or pebbles. This is the base and it allows for water to drain away. People can color it as thick as they like.
  3. Handfuls of driftwood, shells or small plants can also be used in the terrarium. All these parts can nicely get together and look gorgeous along with the moss balls making it look really natural.
  4. The Marimo moss balls should gently touch the substrate and decor. They need enough room to float and swim around naturally. It is also important not to fill the pot to the top so that there is room for larger plants.
  5. Dechlorinated water should be added gradually to the container. Be careful not to disturb the placement of the moss balls or decorative items. People must use room-temperature water because temperature extremes can stress the moss balls.

How to Care For Moss Balls

They are easy to care for and look great and can be an excellent addition to any home or aquarium.

How to Care For Moss Balls

1. Water Requirements

Moss balls do better in clean, non-chlorinated water. Dechlorinated tap water, spring water or mineral filtered water should be used in order for them to have access to salts and minerals. Distilled water must not be used as it lacks minerals and actually may not support their growth. Changing the water every 1 to 2 weeks is essential for keeping the water fresh and not allowing it to become stagnant. This also helps the moss balls and the environment around them remain healthy.

2. Lighting

Moss balls prefer low to medium indirect light. Avoid direct sunlight too, as it will make them brown or ruined. They can be placed under LED aquarium lighting or even in ambient room light. Giving them the perfect amount of light will make them healthy without burning up this tender plant. It’s important to place them in an area where they can receive gentle, indirect light. 

3. Temperature

Marimo moss balls should be kept at an ideal temperature of 65-75°F (18-24°C). They should be stored away from direct heat sources, e.g., radiators or heaters and from temperature fluctuation areas. Storing them in a cool, moderate-temperature environment allows them to grow properly and keep their bright green color.

4. Maintenance

Marimo moss balls are easy to care for. To help the balls maintain their shape, roll them occasionally every 1 to 2 weeks. This composting aids in their even growth and round shape. If the moss balls begin to float, that’s a sign that some air has gotten trapped inside. Gently squeeze them under water to release any air, in order for them to sink down to the bottom to retain their shape.
