How to remove the moss on your terrace? 7 radical tips

After our tips against lichens on roof tiles, it’s time to move on to removing moss from the terrace! Indeed, mosses have the gift of inviting themselves to our paths, between the garden slabs. Indeed, weeds, mosses and lichens always creep into hard-to-reach places and quickly colonize our terraces and balconies. Not only does it not look clean, it also stains and slips. And depending on the pavement, we can’t always afford a high-pressure cleaning with a karcher to loosen them. This can make the plates porous and affect the watertightness of your outdoor space. So here are some chemical-free tips to get rid of patio moss.

Naturally, in this area it is possible to carry out preventive waterproofing treatment to prevent its reappearance in case of humidity and lack of sunlight. In addition, there is certainly also a ready-to-use anti-foam gel or spray treatment on the market. However, beware of herbicides that are often toxic and not very ecological. As for bleach, it eats away at materials and damages the patio while contaminating the soil and killing your plants. So choose mechanical solutions and natural products from grandma without any danger!

A high-pressure cleaner is not always recommended on facades, roofs, gutters and terraces. On the other hand, you can rely on brushing and elbow grease for gentler removal of dirt and mold. Against the moss, gently rub and scrape your terrace with a broom, a stiff brush or a spatula. Then rinse carefully so as not to damage the treated surface, especially not on a wooden terrace. This mechanical cleaning will make it possible to remove the thick foam residues before applying a treatment chosen below.

2) Recycled cooking water as an anti-foam treatment for patios

Cooking water for rice, cooking water for potatoes, cooking water for pasta… We often recommend that you save your cooking water for reuse! While your water is still warm, it can help prevent the spread of foam on the various coatings in your outdoor areas. And it works even better with starchy or salty water. Simply pour it onto all surfaces to be treated and take your time to brush and scrub a bit.

3) No cooking water at hand? Use salt water!

To eradicate mosses with salt water, the affected area must be cleaned away from lawns, ponds, plants and other vegetation. Salt is not good for the health of the plantations (it is a very corrosive weed killer). Not biodegradable, it also carries risks pollute the soil. To use it, dilute coarse salt in water (eg rainwater if you get it). Then proceed to apply the product with a sprayer and rinse immediately. Salt does indeed have a fast effect. Alternatively, you can also dig at the root of the foam and sprinkle some coarse salt on it before rinsing it off quickly. It’s very effective!

4) Soap to remove suds

If you have basil essential oil with weed killer and fungicidal properties, you can add a few drops to the bucket to make the product even more fungicidal. Dip your broom in it and scrub the surface to be treated. Repeat if necessary. Then leave it on for half a day before brushing and rinsing.
