Growing moss on plastic is possible, but it may require some extra steps to ensure success. Some types of moss, such as Taiwan moss, will stick to almost any surface, while others like Xmas moss may be more selective. It's important to note that some plastics may have painted coatings that can flake off over time, taking the moss with it. To avoid this, one could consider sanding down the plastic to remove the paint and provide a better surface for the moss to grip. Additionally, using glue or a moss milkshake made from buttermilk, water, and moss can aid in attaching moss to plastic surfaces.

Using glue to attach moss to plastic
While moss can grow on almost any surface, attaching it to plastic can be challenging due to its smooth and non-porous nature. However, with the help of glue, it is possible to adhere moss to plastic and create a unique decorative element or a miniature ecosystem. Here is a step-by-step guide on using glue to attach moss to plastic:
Selecting the Right Moss and Glue
Choose a type of moss that is known to spread and attach to various surfaces, such as Taiwan moss. Avoid moss that is finicky about its growing conditions, like Xmas moss. For the glue, opt for cyanoacrylate super glue, which can be found at craft stores or hardware stores. The gel form of super glue is easier to work with than the liquid form.
Preparing the Plastic Surface
If the plastic surface has any paint or coating, consider sanding it down to create a better grip for the moss. Ensure the plastic is clean and dry before gluing. If the plastic will be submerged in water, such as in an aquarium, ensure that the glue is suitable for aquatic use and will not contaminate the water.
Gluing the Moss
Start by blotting the moss with a paper towel to remove any excess moisture. Apply a small amount of glue to the plastic surface, spreading it evenly in the desired area. Take a small clump of moss and gently press it into the glue. Avoid using tweezers, as the glue may cause the moss to stick to them. If necessary, use a toothpick or similar tool to nudge the moss into place.
Spreading the Glue Through the Moss
After attaching the moss, use a paper towel to dab the moss and surrounding plastic. This will help spread the glue through the moss, creating a stronger bond. Be careful not to use too much glue, as it may leave streaks on the plastic. If working with wood, you can blot the glue with kitchen paper to avoid streaks.
Caring for the Moss
Moss requires moisture to thrive. If the glued moss starts to dry out, gently mist it with water to maintain its health. Keep in mind that the glued areas of the moss may die off over time, so it is essential to have a large enough plant to compensate for any potential loss. With proper care, the moss should continue to grow and spread on the plastic surface.

Choosing the right moss type
Choosing the right type of moss is essential for growing moss on plastic. While moss can attach itself to almost any surface, different types of moss have varying levels of adaptability and growth patterns. For instance, Taiwan moss is known for its ability to stick to any surface, whereas Xmas moss may be more selective.
When choosing a moss type, it is important to consider the specific characteristics of plastic as a growth substrate. Plastic surfaces can vary in terms of smoothness, porosity, and the presence of coatings or paint. These factors can influence how well the moss adheres to the plastic and spreads across it. If the plastic has a smooth surface, methods such as gluing or tying the moss may be more effective.
Additionally, some plastics may contain heavy metals or chemicals that can be harmful to moss. For example, chromated copper arsenic in pressure-treated wood can leach into water and negatively impact moss growth. Similarly, zinc is known to retard moss growth. When choosing a moss type, consider selecting a variety that is known to be resilient and adaptable, especially if the plastic surface may contain contaminants.
Another factor to consider is the growth habit of the moss. Some mosses grow in clumps or tufts, while others spread laterally and form a dense carpet. If you are aiming for a specific aesthetic or coverage pattern on the plastic surface, choose a moss type that aligns with your desired effect. For example, if you want a lush, carpet-like appearance, select a moss variety that naturally spreads horizontally.
Lastly, consider the maintenance requirements of different moss types. While moss is generally low-maintenance, some varieties may have specific moisture, light, or nutrient needs. If you are looking for a moss that requires minimal care, opt for varieties that thrive in shady conditions and have low water needs. By choosing a moss type that aligns with your specific environmental conditions, you can increase the likelihood of successful growth on plastic.

Preparing the plastic surface
Firstly, it's important to select the right type of plastic. Choose a plastic surface that has a porous or rough texture, as this will provide a better grip for the moss. Avoid using painted plastic surfaces, as the paint may flake off over time, potentially taking the moss with it. If you already have a smooth plastic surface, consider sanding it down gently to create a rougher texture, which will provide a better anchor for the moss.
Once you have the right plastic surface, you can enhance its ability to grip the moss by using an adhesive. Super glue, specifically Cyanoacrylate super glue in gel form, is an effective option. Apply small dots of glue to the plastic surface and then attach a few pieces or a single strand of moss, applying a little pressure to ensure adhesion. The glue will provide a strong hold and, although it may leave a white residue, the moss should eventually cover it.
Another option is to use a natural adhesive like yogurt or buttermilk. Create a mixture by blending yogurt or buttermilk with moss, either live or dead, and water. This "moss milkshake" can then be painted onto the plastic surface with a brush. Keep in mind that this method requires regular misting to maintain moisture for the first few weeks.
If you prefer a mechanical method, you can try using mesh. Nylon butterfly netting or galvanised steel mesh can be placed over the plastic surface and sewn or tied down, providing a base for the moss to grip onto. The mesh method may take a little longer, as you'll need to wait for the moss to grow and cover the netting.
With any of these methods, it's important to remember that moss generally thrives in shady, moist environments. Ensure that the plastic surface is located in an area that receives minimal direct sunlight and has a consistent source of moisture to promote moss growth.

Using a moss milkshake
While it is possible to grow moss on plastic, it is important to note that some types of moss, such as Taiwan moss, will stick to plastic, while others, such as Xmas moss, may not. Additionally, painted plastic may flake off over time, taking the moss along with it.
One method for growing moss on plastic is by using a "moss milkshake". Here is a guide on how to create and use a moss milkshake to grow moss on plastic:
Ingredients and Preparation:
For the moss milkshake, you will need a handful of moss with some dirt attached, and a liquid base such as buttermilk or yogurt. You can also experiment with other ingredients such as cornstarch, beer, peanut butter, sucrose, or absorbing crystals. However, it is important to note that these ingredients do not provide additional nutrients for the moss and may only affect the pH.
To prepare the moss milkshake, simply blend the moss and the liquid base in a blender until the moss is well blended and the mixture resembles a thick goop. It is normal for the mixture to look like mud or sludge at first. You can also manually break down the moss instead of using a blender, but this may be a more tedious process.
Application and Maintenance:
Once you have your moss milkshake mixture, you can apply it to the plastic surface. Spread a thin layer of the mixture onto the plastic, ensuring that it is evenly coated. Keep the plastic surface fairly moist to encourage moss growth.
In the first week, you may notice the growth of fluffy white mold on the plastic. However, by the second week, the moss should begin to show itself as the mold dies away. By the end of the second week, you should see the moss growing nicely on the plastic surface.
It is important to note that the moss milkshake method may take a significant amount of time to achieve noticeable growth. Additionally, the food-based ingredients in the mixture may attract unwanted critters or pets, so take the necessary precautions to avoid any interference with your project.
Tips and Variations:
- If you are concerned about the blender, consider using a separate blender dedicated to preparing moss milkshakes, as the process can be messy and may clog up the blender blades.
- To enhance the mixture for growing moss on stone surfaces, you can add pottery clay or any appropriate type of clay.
- If you are creating a moss terrarium, avoid using this method if you plan to house amphibians, as mold and fungi can be harmful to their skin.
- For movable moss, you can apply the moss milkshake to lizard matting carpet, as it holds moisture well.

Maintaining the moss
The type of container you use is also important for maintaining healthy moss. Some materials will kill moss, while others will stop it from spreading. Moss is sensitive to heavy metals and some chemicals, so it is best to use glass or plastic containers. If using plastic, be aware that some plastics have painted coatings that may flake off over time, taking the moss with it. In this case, you could sand down the plastic to remove the paint and give the moss a better surface to grip.
If you notice brown patches on your moss, don't panic. Ageing moss can turn brown naturally, and if kept properly, most of it will stay green. You can try to revive the moss by placing it in a clear bag, misting the bag with water, and then sealing the bag so that all of the moss is covered. Leave it for 1-2 weeks, and the greenhouse effect should help bring your moss back to life.
If your moss is in a terrarium, you may have to deal with mould at some point. Mould often occurs as a result of overwatering, and you will see white, cotton-like spots on the surface of the moss. Try wiping the mould away gently and then let some water evaporate before replacing the lid. If the mould doesn't come off, use a knife or scissors to carefully remove the affected moss to prevent it from spreading, and then replace it with fresh moss.
Finally, remember that moss likes its soil packed and firm, and it thrives in acidic environments with a lower pH level, usually between 5.0 and 6.0.
