How to get rid of moss on your patio? Anyone who has tried to remove moss from a patio knows that it can be a difficult and frustrating task. Moss can take root overnight, and can quickly turn a nice smooth patio surface into an uneven mess.

Fortunately, there are also a number of safe and effective moss removal methods that you can use at home which we will talk about in this article.

Why You Have A Moss Problem

Before we go through the methods on how to remove moss from your patio, it is important to understand why moss is growing there in the first place.

By knowing the causes, you can take appropriate measures to prevent it from growing back. So here are some of the reasons why moss is growing on your patio!

Patio Has No Direct Sunlight: One of the main reasons for moss growth is a lack of sunlight. If your patio is in a shaded area, this will provide the perfect environment for moss to grow.

Patio Has Lots Of Moisture: Moss thrives in moist environments, so if your patio is constantly wet or humid, or has poor drainage, this will result in the accumulation of moisture that favors moss growth.

Moss Spores From Nearby Trees: It’s tough to prevent the spread of moss spores because they are very resilient, and if just one moss spore was to break off it can easily spread to an area on your patio.

Although moss isn’t harmful to human beings and pets, it should be eliminated on your patio before it can cause damage to the slabs.

Springtime is generally considered to be the best time to remove moss. This is because the moss is the most active, absorbing nutrients from rainwater and moisture in the air.

For example, if you were to use a moss killer and the moss is dormant (like in the summer) it’s less likely to absorb the solution which means it won’t be very effective and could end up growing back weeks later.
