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.
How to Remove Moss from Block Paving
Removing moss from block paving is essential to ensure that the surface is safe and in good condition. Here are the steps to remove moss:
Step 1: Gather the Right Tools
Before you begin, you will need to gather the right tools. You will need a stiff brush, a pressure washer, and a moss killer. Make sure to read the instructions on the moss killer before using it to prevent any damage / harm to local wildlife.
Step 2: Remove Any Debris
Remove any debris, such as leaves or twigs, from the block paving before you start cleaning. This will ensure that the moss killer can penetrate the surface.
Step 3: Apply Moss Killer
Apply the moss killer according to the instructions on the label. Make sure to wear protective gloves and clothing, as the moss killer can be harmful to skin and eyes.
Step 4: Wait for the Moss to Die
The moss will start to die within a few hours of applying the moss killer. Wait for the moss to turn brown before moving onto the next step.
Step 5: Use a Stiff Brush
Use a stiff brush to scrub away the dead moss. This will help to remove the moss from the surface of the block paving.
