Moss Killers You Should Avoid Using

If you have moss growing on your block paving, you may be tempted to reach for a chemical moss killer. However, many of these products contain harmful chemicals that can damage your paving and harm the environment.

Additionally, they often only kill the surface moss, while the some that grow between the pavers remain intact, meaning that the moss will quickly regrow.

One of the ingredients that moss killers should not have is bleach.

Important: Depending on what type of pavers you have! Bleach can potentially ruin your block paving by discoloring the suface, turning it pale. Bleach can also be dangerous and toxic to surrounding areas, like grass, and live plants!

Suppose you also use a moss killer with bleach near your grass and other vegetation. It might get absorbed by the soil and ultimately kill your grass and other plants.

These types of moss killers are also highly corrosive and toxic to pets and children, even adults.

Lastly, check if your moss killer has zinc sulfate. This substance is also highly corrosive and might be dangerous to you and your loved ones’ health, including pets.

You should also apply it with a garden sprayer to ensure that all parts will be covered.

It would be best if you also cleaned your pavement by sweeping away any dust, dirt, dried leaves, and other garbage before applying moss killers on it.

Lastly, you should wear gloves and goggles when applying moss killer to avoid potential allergies and injuries.

How Often Should You Apply Moss Killer To Block Paving?

Moss killer is a great way to keep your block paving looking its best. But how often should you apply it? The answer depends on a few factors, including the type of moss killer you’re using and the amount of traffic your paving sees.

Moss and algae can quickly take over block paving if left untreated, making it slippery and unsafe. In addition, the growth of moss and algae can cause the paving to degrade over time.

Take Note: It’s very important to regularly apply moss killer to your block paving. Many experts recommend applying moss killer at least once or twice a year, preferably in the spring or early summer.

This will help to prevent the growth of moss and algae before it gets out of control. If you live in an area with a lot of rain, you may need to apply moss killer more frequently.
