Moss walls are a beautiful addition to any indoor space. But like all living art, they come with their own set of unique problems, with some that can often get worse if not corrected. Here we discuss some of the most common moss wall problems we have encountered, provide practical solutions for how to treat them and give advice on how to prevent them from reoccurring. 

Excessive moisture: 

Moss walls can become damp if watered too frequently or in large amounts. This can lead to overgrowth of the moss and potential mold issues. For more information on adequately watering your moss wall, see our article: Do moss walls require irrigation or watering systems.

How to treat excessive moisture:

  1. If there is standing water on the moss, gently blot it with a clean, dry cloth or paper towels. Be careful not to press too hard and damage the moss. 
  2. If there is still some excess moisture on the moss wall, you can open any nearby windows, use fans, or place the moss in a spot with better airflow to help it dry out.
  3. If mold has started to grow, gently remove the affected areas of moss. You can also lightly spray the remaining moss with a diluted hydrogen peroxide solution (1 part hydrogen peroxide to 10 parts water) to discourage mold growth.
  4. If any parts of the moss have turned brown or mushy, carefully trim them away with clean, sharp scissors or tweezers. This will also help to encourage new growth.

How to prevent excessive moisture:

  1. Adjust your watering schedule. Try to reduce watering the moss wall if it feels too damp. 
  2. The best way to water your moss wall is to use a misting spray bottle and spray it on a schedule. Try misting twice a week and inspect the moss wall to see how it reacts. You can increase or decrease the amount of misting after a few weeks.
  3. If your moss wall has a container, ensure it has proper drainage. If not, consider putting some drainage holes in the frame or holster of your moss wall.

One key take away when caring for your moss wall is to not rush. Reviving over watered moss takes time. It may take weeks or even months for the moss to fully recover. Be patient and continue to provide appropriate care and you will see it start to change for the better.

Poor lighting: 

Insufficient light can cause moss to grow much slower, turn brown or possibly die. Mosses typically thrive in low to moderate light conditions, but they do require some indirect or filtered light to grow well.

Each moss species has a particular environment it prefers, including direct or indirect sunlight. Determine what type of moss you have to help identify the best location for your moss wall. For more information, see our article: How to select the right species for your moss wall.

How to treat poor lighting:

  1. Relocate the moss wall to a brighter area. North-facing windows are often ideal because they provide consistent, gentle light without direct sun exposure.
  2. If moving the moss wall isn’t an option, consider supplementing with artificial lighting. LED grow lights designed for low-light plants can provide the necessary light spectrum for moss growth. Hang the lights above the moss wall and set a timer to simulate a natural day-night cycle. Moss generally benefits from 8-12 hours of light per day.

How to prevent poor lighting:

  1. Before building your moss wall, chose moss species that work well with the location you want to install the moss wall.
  2. If your moss wall is moveable, try moving it to a location where it can receive indirect sunlight on a frequent schedule.
  3. If the moss wall is near objects or plants blocking light, trim or move these obstructions to allow more light to reach the moss.
  4. Ensure that the surface of the moss wall is clean and free from dust and debris. This allows maximum light penetration and promotes moss health.

Pest infestation: 

Since your moss wall is a living plant, sometimes unwanted pests will find it a too nice of a meal to resist. Spend a bit of time each week inspecting your moss wall for any signs of pests, bugs or damage.

How to treat pest infestation:

  1. Carefully inspect your moss wall to identify the type of pests infesting it. Common moss pests include mites, aphids, springtails, and tiny insects.
  2. If possible, isolate the affected portion of the moss wall to prevent the pests from spreading to healthy areas.
  3. Use a soft brush, tweezers, or a gentle stream of water to manually remove the pests from the moss. Be careful not to damage the moss in the process.
  4. Trim away heavily infested or damaged parts of the moss. This can help reduce the pest population and allow the healthy moss to recover.
  5. Dilute neem oil or insecticidal soap as per the manufacturer’s instructions. Gently spray the affected moss with the solution. These natural remedies can help control pests while being less harmful to the moss.

How to prevent pest infestation:

  1.  If you plan to add new moss or materials to your moss wall, quarantine them separately for a few weeks to ensure they are not carrying pests before introducing them to your established moss.
  2. Keep the area around the moss wall clean to prevent debris and decaying plant matter from attracting pests.
  3. Don’t overcrowd the moss wall with too many plants or materials. Overcrowding can create hiding spots for pests and make it challenging to control infestations.
  4. Learn about the specific pests that affect moss and their life cycles. Understanding the common moss wall pests will help you develop effective control strategies. For more information, see our article: Safeguarding Your Moss Wall: How To Pinpoint and Eliminate Pests.

Remember that early detection and prompt action are key to preserving the health and appearance of your moss wall. With proper care and vigilance, you can create an enchanting green oasis that thrives for years to come.

Uneven growth: 

If left for long periods, moss may grow unevenly or in patches on your wall. Uneven growth can occur due to various factors, including differences in light exposure, moisture levels, or substrate conditions. Periodic inspection and trimming of the moss will help level out over-grown areas; where as reintroducing new moss or encouraging growth will help fill thinning areas. 

How to treat uneven growth:

  1. Examine your moss closely to identify the specific areas where growth is uneven. Determine the potential causes, such as variations in lighting, moisture, or substrate.
  2. If you suspect uneven lighting as the cause, consider moving the moss wall to a more balanced location. Ensure that all parts of the moss receive an equal amount of indirect or filtered light.
  3. Carefully groom the moss by trimming or gently brushing it to encourage more uniform growth. You can also rearrange patches of moss to fill in uneven areas.
  4. Check the substrate or base material used for your moss wall. Ensure it’s consistent in terms of moisture retention and texture throughout the wall. Adjust or replace the substrate if necessary

How to prevent uneven growth:

  1. Ensure that the substrate or base material used for your moss wall is consistent throughout. This uniformity helps maintain consistent moisture levels and promotes even growth.
  2. Periodically inspect your wall to identify areas of strong or weak growth.
  3. Position the moss wall in a location where it receives uniform, indirect or filtered light. Avoid placing it in areas with extreme variations in lighting.
  4. Groom the moss regularly to encourage even growth. Trim or gently brush the moss to distribute nutrients and prevent overgrowth in certain areas.
  5. Space out moss patches or pieces evenly when creating or maintaining the moss wall. Overcrowding can lead to competition for resources and uneven growth.
  6. Using similar species of moss on the wall may help to ensure that they grow at the same rate.

By implementing these preventive measures and maintaining a balanced care routine, you can significantly reduce the chances of uneven growth on your moss wall and enjoy a lush and harmonious display.

Algae growth: 

Algae can out compete your moss if the conditions are favorable. Treating your moss with the right amount of water and care will help prevent algae growth.

How to treat algae growth:

  1. Determine the specific type of algae present on your wall, as different algae may require different treatment approaches.
  2. Use a soft brush or toothbrush to gently scrub the affected areas of the moss wall. Be careful not to damage the moss while removing the algae.
  3. Dilute hydrogen peroxide with water (about 1 part hydrogen peroxide to 10 parts water) and lightly spray the affected areas. Be cautious when using hydrogen peroxide, as it can harm moss if used in excess.

How to prevent algae growth:

  1. Algae thrive in well-lit conditions. Adjust the lighting around the moss to reduce direct or intense light exposure. Move the wall to a shadier location if necessary.
  2. Ensure that moisture levels are consistent throughout the moss wall. Algae can thrive in areas with fluctuating moisture levels. Avoid over-watering or under-watering the moss.
  3. Enhance air circulation around the moss by using fans or opening windows. Good airflow can help keep moisture levels stable and discourage algae growth.
  4. Consider introducing algae-eating species, such as small snails or aquatic animals like shrimp or fish (if the moss is in a water feature). These creatures can help control algae growth.

With some periodic maintenance using these tips and tricks, your moss wall will be bright, clean and vibrant for years to come.
