Building A Marimo Terrarium


The steps:

Step 1 - Name your Terrarium: Naming your terrarium kit helps us to pack your items  appropriately so that you will receive all of your terrarium ingredients grouped together. This is especially helpful if you are building multiple terrariums on one order, or adding other loose items to your order from elsewhere in our store.

Step 2 - Choose your Container: Select your favorite container from our hand selected collection. Container size and other details are listed next to the photo. All of our marimo containers are an appropriate size for our miniature marimo, but the openings differ so be sure to check the details of your container.

Step 3 - Add your Base Layer: Choose from our selection of terrarium sand and pebbles (Click on the image to select your chosen color). We recommend using a combination of sand and pebbles in your terrarium (most of marimo terrariums use a ratio of 1 part pebbles to 4 parts sand), but just sand or pebbles is a fine option as well.

Step 4 - Select your Plants: We are currently only offering miniature sized marimo, with plans to add more sizes in the future. Mini-marimo look great in pairs (or more) in a terrarium, so don't be afraid to build with more than one!

Step 5 - Create your World: Let the fun begin! In this section you will find a wide variety of elements to customize and personalize your terrarium. All of the elements in this section are small enough to fit through the smallest of our container openings, and provide a variety of options for creating your own unique terrarium.

Plant Like a Pro...

Designing and planting your terrarium is a fun and creative process. Follow your imagination and pay attention to the elements that catch your eye. Every person is unique, and everyone's style will reflect that. Below are some thoughts, tips and tricks that I consider when designing our terrariums. Hopefully they will be helpful to you as well.       -Matthew Herbage, Owner.

Selecting your container:

  • This step is mainly about choosing the container that best suits your mood, but there is one thing to consider. Most of our container options are round, and will magnify the element within once filled with water. This is a highly desirable effect, as it creates an illusion of expansive terrain larger than the container itself. In addition, by playing with the position of the elements within, you can dramatically change their size, and the overall feel of the terrarium. Our "flat bottle" and "pillar" are the only two container options that have limited or no magnification.
Selecting your base layer:
  • While pebbles as a base layer work well for air plant terrariums, and are perfect for certain themes, overall we find decorative sand to be the more versatile of the two options. It is easier to nestle the base of your plants in sand (lending to the "planted" feel of your terrarium). In addition, taller elements (such as driftwood) can be stood upright more easily in sand.
Selecting your elements:
  • When selecting decorative elements, it is often a good approach to choose a mix of sizes, including at least one large (relative to the size of your container) element. This helps to provide a landscaped feel, and adds focal points to your terrarium. Larger elements also help to fill negative space. For marimo terrariums, black sea fan is the top option for filling space. In our opinion, it is a must have.
Designing and building your terrarium:
  • The most important tip when building your terrarium is to have fun. Don't force it, and try to remain open to the end result. Often times the terrarium will begin to take shape as you start adding ingredients, and it doesn't always end up how you thought it would. The more fluid you can be in your design the better.
  • Remember to rinse your base layer well before adding your remaining elements. Some pebbles/sand require rinsing multiple times before the water remains clear.
  • Keep in mind smaller elements (such as small rocks, shells etc.) will mix in with the sand in your terrarium. By using the stir stick sent with your terrarium you can dig in and bring them back to the surface. Really small elements such as terrarium pebbles will always remain somewhat mixed, so you may want to add a little bit more than what you want to be visible.
  • Sometimes air bubbles will get trapped in the chamber of small seashells, causing them to float. To solve this, pre-fill them with water before adding them to your terrarium.
  • Be sure to play with the positioning of your decorative elements. Because of the magnifying effect that occurs when most of the terrarium containers are filled with water, objects placed further from the front will appear significantly larger than those placed closer. This can alter the overall look dramatically, and is worth exploring!
