Moss growth on tarmac can be unsightly and hazardous. If left unattended, it can cause the surface to become slippery, leading to potential accidents. In this article, we will provide you with the answers to frequently asked questions about killing moss on tarmac, along with some expert tips to help you effectively tackle this issue in 2023.

1. What causes moss to grow on tarmac?

Moss thrives in damp and shady areas. Tarmac surfaces that receive minimal sunlight and experience high levels of moisture are ideal breeding grounds for moss. The presence of organic matter, such as fallen leaves or debris, can also contribute to moss growth.

2. Why is it important to kill moss on tarmac?

Moss can compromise the integrity of tarmac surfaces by trapping moisture and causing cracks. Additionally, its slippery nature poses a safety risk, especially during wet weather conditions. Regularly removing moss helps to maintain the longevity and safety of tarmac surfaces.

3. How can I kill moss on tarmac?

There are several methods you can employ to effectively kill moss on tarmac:

a) Manual Removal

Start by manually removing the visible moss using a stiff brush or a scraper. Be sure to wear protective gloves and goggles to avoid any injuries. This method is suitable for small areas with minimal moss growth.

b) Chemical Moss Killers

Chemical moss killers, available in most garden centers, are effective in killing moss on tarmac. Follow the instructions provided by the manufacturer carefully. It is important to choose a moss killer that is safe for use on tarmac surfaces to prevent any damage.

c) Pressure Washing

Using a pressure washer can help remove moss from tarmac surfaces. However, be cautious not to use excessive pressure as it may damage the tarmac. Start with a lower pressure setting and gradually increase if necessary.

4. Can I prevent moss from growing on tarmac?

While it is difficult to completely prevent moss growth, there are measures you can take to minimize its occurrence:

a) Improve Sunlight Exposure

Trim overhanging trees or bushes to allow more sunlight to reach the tarmac surface. Moss thrives in shady areas, so increasing sunlight exposure can hinder its growth.

b) Regular Maintenance

Regularly sweep and remove any fallen leaves or debris from the tarmac surface. This reduces the accumulation of organic matter, which moss feeds on.

c) Apply Moss Inhibitors

Consider using moss inhibitors, such as iron sulfate or proprietary moss control products, to prevent moss growth. These inhibitors work by altering the pH levels of the tarmac surface, making it less favorable for moss to grow.

5. Are there any eco-friendly alternatives to chemical moss killers?

If you prefer to avoid chemical moss killers, there are eco-friendly alternatives you can try. One option is to create a homemade solution using a mixture of equal parts vinegar and water. Spray this solution onto the moss-infested areas and leave it to dry. Vinegar has natural antimicrobial properties that can help kill moss.


Killing moss on tarmac is crucial for both aesthetics and safety. By following the tips provided above and regularly maintaining your tarmac surfaces, you can effectively eliminate moss and prevent its regrowth. Always prioritize safety when carrying out any moss removal methods and ensure you choose the most suitable option for your specific situation.
