Can You Put Baking Soda Directly on The Moss?

A moss is a low-growing plant that forms picturesque colonies in damp climates and boasts garden visibility. There are more than 2,500 moss species, but they all live under the ground and do not have any leaves.

Mosses can grow without soil or sunlight, making them a popular addition to many homes.

Yes, You can use baking soda directly on moss as a natural way to control its growth. Most people use baking soda, or sodium bicarbonate, as a household remedy for various cleaning and gardening purposes. It alters the pH level on the surface it touches, creating a less favorable environment for moss growth.

To use baking soda on moss, follow these steps:

  1. Identify the areas where moss is growing. Moss typically thrives in damp and shaded areas such as sidewalks, roofs, or garden paths.
  2. Sprinkle the baking soda over the areas of moss growth, applying about a 1/4 inch thick in a circular pattern.
  3. Scrub the baking soda into the moss with a stiff bristle brush to loosen its roots and kill any existing moss. This also serves to break up any mold or mildew that may be present, preventing it from spreading to other areas of your landscape.
  4. Rake the loose baking soda moss and mold the mixture into a plastic bag. Baking soda is generally nontoxic, but these steps will keep it from getting into your soil or water sources.
  5. Use a garden hose to clean the affected areas of any remaining baking soda, mold, or moss residue. You may also consider planting native plants in these areas to prevent them from re-infesting when it rains.

What Keeps Moss from Growing Back?

FactorsDescriptionPreventive Measures
SunlightMoss thrives in shady and damp environments. Exposing the area to direct sunlight inhibits moss growth.Trim overhanging trees or plants that create shade. Increase sunlight penetration by pruning branches or using reflective surfaces.
MoistureMoss requires constant moisture to grow. Reducing moisture levels in the area prevents moss from regrowing.Improve drainage by removing debris, clearing gutters, or adding drainage channels. Avoid over-watering plants or lawns.
Air CirculationMoss favors still, stagnant air conditions. Promoting air circulation helps dry out the area and discourages moss growth.Prune surrounding vegetation to enhance airflow. Use fans or install windbreakers to increase air movement.
Soil AcidityMoss thrives in acidic soil conditions. Adjusting the soil pH to a more neutral or alkaline range prevents moss from re-establishing.Test soil pH and apply lime or other soil amendments to increase pH levels, Avoid using acidic fertilizers.
Nutrient LevelsMoss prefers nutrient-poor environments. Ensuring optimal nutrient levels in the soil promotes healthier plants and reduces moss growth.Do a soil test and amend the soil with appropriate fertilizers or organic matter. Follow proper lawn care practices.
Physical RemovalRemoving existing moss manually or with appropriate tools helps prevent its regrowth.Use a stiff brush, rake, or pressure washer to remove moss physically. Regularly clean and maintain surfaces susceptible to moss growth.

Is It Easier to Remove Moss When Wet Or Dry?

Removing moss can be more accessible when wet rather than dry due to several factors related to moss’s properties and growth patterns.

When moss is wet, it becomes softer and more pliable, making it easier to dislodge and remove from surfaces. Here’s an explanation of why it’s easier to remove moss when it’s wet:

  1. Hydration: Moss thrives in damp and moist environments. When the moss is wet, it absorbs water, becoming hydrated and more flexible. This hydration softens the moss, making it less resistant to removal.
  2. Adhesion: Moss has tiny root-like structures called rhizoids that help it attach firmly to surfaces. When the moss is dry, these rhizoids adhere tightly, making it challenging to detach it from the surface.

However, when the moss is wet, the rhizoids lose their grip, and the moss becomes less firmly attached, allowing for easier removal.

  1. Structural integrity: Moss consists of delicate filaments and structures that can break easily when wet.

Dry moss tends to be more brittle and resistant to removal without causing damage to underlying surfaces. When wet, the moss becomes more pliable, reducing the risk of damaging the surface while removing it.

  1. Penetration: Water can seep into the gaps between moss and the surface it is growing on, facilitating the loosening of moss from the substrate. The water helps to penetrate the moss’s structure, making it easier to dislodge and remove.

Is Moss Harmful To Humans?

Yes, Moss is harmful. Let’s get right into the six reasons why.

1. Reduces Air quality

Moss can soak up methane and carbon dioxide toxins from the air. This can contribute to environmental problems such as smog.

2. Damages Buildings, Roads, and Bridges

Moss is a natural plant that has developed the ability to break down rocks into the soil through its roots to obtain nutrients for growth.

Mosses have been known to cling onto building spires, bases, pillars, roadways, etc., which can cause damage or disruption for passing traffic or construction in those areas.

3. Destroys Property Value

People are motivated to maintain and improve their property, which is one reason why there has been an increase in masonry containment.

The risk of moss growing on a structure or building can cause it to lose value and become unusable. That means less money for repair or maintenance.

4. Destroys Natural Beauty

Moss negatively impacts the aesthetic natural beauty of buildings such as landscapes, mountain ranges, lakes, and streams. It also takes tiny, natural sediments and particles that help make the earth more fertile and productive.

5. Loses Nutrients

Moss can be detrimental if it covers a building or structure with much vegetation, including trees or food crops.

Moss will take plant nutrients and decrease the available nutrition on that property. That’s bad for human consumption since our bodies depend on these crucial substances essential to life.

Does Baking Soda Kill Moss and Harm Anything Else?

Yes, Baking soda can kill moss, but it may also harm other plants and organisms if not used carefully. Baking soda boasts an alkaline substance that can alter the pH levels of its surroundings.

Mosses thrive in acidic environments, so applying baking soda can disrupt their growth and eventually kill them.

When using baking soda to control moss, it’s crucial to consider the potential side effects. It can enhance the pH of the soil, making it more alkaline.

This change in pH can be detrimental to certain plants, especially those that prefer acidic conditions. Acid-loving plants like azaleas, blueberries, and rhododendrons may suffer if exposed to high alkalinity levels.

The altered pH may also negatively affect some beneficial soil organisms, such as earthworms and beneficial bacteria.

To minimize harm, it’s vital to apply baking soda to moss-infested areas and avoid contact with surrounding plants and soil. A targeted application can help mitigate the risk of unintended damage.

It’s also advisable to water the treated areas thoroughly after applying baking soda to help dilute and wash away excess alkalinity.

It’s worth noting that while baking soda can kill moss, it may not completely eradicate it from the area. Moss is resilient and can quickly regrow if the underlying conditions favor its growth.

Therefore, addressing the underlying factors that promote moss growth, such as excess moisture, shade, or poor drainage, is essential to prevent its recurrence.


Moss on buildings is a problem for many people. Moss can multiply and be challenging to remove, damaging the building or property it grows on.

The best solution for removing moss is to prevent it from growing in the first place. Try using a non-chemical approach to control the moss when this is impossible.
