If you have block paving in your garden or driveway, you may have noticed moss starting to grow between the cracks. While it may look nice and add a natural touch, it can also be slippery and unsafe. Additionally, moss can damage the blocks by retaining moisture and causing cracks. In this article, I will discuss how to remove and prevent moss growing on your block paving.

Why Does Moss Grow on Block Paving?

Moss is a common plant that grows in moist and shady areas. Block paving is an ideal environment for moss to grow due to the cracks between the blocks. These cracks can retain moisture, providing the perfect growing environment for moss. Additionally, the lack of sunlight can help the moss thrive.

The gaps between your blocks are also a perfect breeding ground for block paving weeds.
