How To Grow Moss On A Bonsai

Moss is affordable, spreads quickly, and creates a thriving environment for your Bonsai. Cultivating this moss landscape enhances the look of your miniature tree while adding to its health. The harder question to answer is why not grow moss on a Bonsai? The five steps to growing moss on your Bonsai are broken down in detail below. 

1. Grow Or Collect Moss Specimens

First, you need to gather the moss you plan to use. Moss can be grown from store-bought spores, or specimens can be collected from the surrounding environment. Growing moss in a separate container takes about one month.  

Amazon offers fern moss, perfect for Bonsai here.

Ensure the container you are using to grow your moss has adequate drainage. Cover the container with a cheesecloth or breathable lid, and mist the spores or specimen once a day until they are ready to be harvested. 

2. Prepare The Top Layer Of Soil Around Your Bonsai

Before you lay your moss around a Bonsai, the top layer of soil needs to be properly prepared. Remove any debris and remove any aerial roots using a sharp pair of root scissors. 

Have a look at these root scissors here on Amazon.

3. Lay One Layer Of Sphagnum Moss

Next, you will put down a layer of sphagnum moss over the top layer of soil. Having sphagnum moss between your soil and fresh moss helps to keep your fresh moss moist and in place. After you lay your sphagnum moss, lightly water to flatten the moss into your soil. 

Find dried sphagnum moss here on Amazon.

4. Arrange Pieces Of Your Cultivated Or Collected Moss 

You can start placing your cultivated or collected moss around your Bonsai. Place your first piece of moss to lean against your tree, then continue to lay your moss in a natural-looking way. Avoid layering your moss as this will decrease the amount of moisture that makes it to the Bonsai roots. 

5. Press Down Your Moss And Apply A Light Mist

With all your moss in place, gently press down on the top using a spoon or spatula to keep everything in place. The last thing you will do is lightly mist the newly positioned moss and let the soil do the rest.

What Moss Do You Use For Bonsai?

There are a variety of mosses that you can use for your Bonsai. The important aspect is to match the soil pH with the individual needs of your moss. You can’t grow moss that likes an alkaline environment in acidic soil.

Alongside different environmental needs, different mosses offer unique looks. You can choose moss that gives off a mountainous appearance, one that is flatter and all sorts of colors.

Always research the moss you plan to use to get familiar with its characteristics, such as the pH, and water requirements. You also want to be familiar with the needs of your Bonsai and try to match the two. Some types of moss you can use for Bonsai include the following:

Each choice offers a different look, and there are even more moss choices outside this list. The moss you use is really up to the look you are going after and the environment you are planting in.

How To Propagate Moss For Bonsai

Growing or propagating the moss for your Bonsai can be done in two different ways, and both are quick and painless. Propagating moss can be done using spores or by collecting established moss. Let’s take a closer look at the process of each method. 

How Do You Use Bonsai Moss Spores?

Bonsai moss spores are great if you plan to use moss over a long period of time on multiple trees. Cultivating moss using spores creates a supply of moss you can consistently take. 

You can buy moss spores from online gardening stores or your local plant nursery. Do your vigilant research on the type of moss you plan to use to ensure it is a good match for your Bonsai and its environment. 

You can find Kyoto moss spores here on Amazon.

Fill a pot or container with standard potting soil. Ensure the soil and your pot have adequate drainage.

You can create additional drainage using a false bottom in your container or pot. A false bottom can be made with stones, charcoal, and a type of mesh screen, with your potting soil placed on top.

Spread your moss spores evenly within your soil. Keep up with daily misting to maintain a moist environment and allow plenty of sunlight to reach your soil.

One month out from laying your spores, you should have moss that is ready to be transplanted around your Bonsai tree. Simply take what you need from the moss pot, and allow the moss to continue growing for use on another tree. 

How Can You Utilize Established Moss?

Propagating moss using established moss is beneficial because you will use moss that you know does well in your environment. Collect moss from your surrounding area, focusing on moss species that grow in areas with plenty of sunlight.

Allow your collected moss to dry out for a couple of days before crumbling it with your hands, creating a dust-like substance. Thoroughly water your Bonsai before sprinkling the moss dust over the top layer of soil. Continue to mist this layer of moss twice a day to promote growth.

How Do You Water A Bonsai Tree With Moss?

Once your moss becomes established, continue to water your Bonsai tree normally. The average Bonsai requires weekly watering; the amount may vary depending on environmental factors like:

  • Temperature
  • Humidity
  • Sunlight
  • Wind
  • Soil choice
  • Size of your tree
  • Size of your pot

Are you noticing your moss is drying out between watering? Use a spray bottle to mist the top of the moss between watering. This allows your moss to get the moisture it needs while avoiding over-watering your Bonsai.

The amount of water your Bonsai tree gets can vary, just like the watering methods. Some methods include watering by rainfall, drip irrigation systems, water immersion, and the use of watering cans or a hose.
