What is moss?

Mosses are small flowerless, non-vascular green plants usually found in damp or shady locations, which are typically in dense clumps or mats. The plants bare no true roots, flowers or seeds and reproduce asexually and via spores.

Moss attaches itself to surfaces through rhizoids, instead of roots like typical plants, and many mosses can even survive dry periods for months, quickly rehydrating after rainfall.

Mosses will grow almost anywhere the conditions are favourable, which given Britain’s mild, damp climate, these beautiful plants flourish. There’s no doubt that mosses add an element of beauty in the right locations, they even help reduce soil erosion, but in the wrong areas, they can be a problem.

Is moss harmful or dangerous?

Moss produces no dangerous fumes or spores and therefore poses no respiratory health risks. Mosses, however, retain and trap moisture, reducing evaporation on the surface it resides such as roofs, leading to internal mold should the fabric of the building degrade, allowing moisture to enter.

The indirect risks from moss growing on hard surfaces such as steps and car parks are that injuries may arise, due to the slippery nature of moss, especially when wet.  Employers, landlords and councils, therefore, have a duty of care to reduce and manage the risk of slips on their premises.

Can moss cause structural or surface damage?

In short, yes, if moss is left too long damage can occur, even from small amounts. The danger with moss is its ability to trap moisture which over time can lead to the degradation of surfaces and structures.

In turf, moss can reduce the aesthetic appearance of your lawn, but it’s the result of other pre-existing conditions and therefore will not cause any damage.

Is it difficult to remove and control moss?

Moss can be challenging to control and will take advantage of the existing environment, spreading in every nook and cranny through division, spores, animals and even human intervention.

There are many manual and mechanical methods of removing moss from roofs, structures and surfaces but from experience, without any treatments from an HSE approved biocide, it quickly returns as the cleaning process alone cannot remove every tiny piece or spores.

There are numerous products on the market, including some products made from blends of organic and natural ingredients, providing options and longevity for all sites.

What services do Wild Ground offer to control moss?

Wild Ground is fully qualified to deal moss on all surfaces, and we are also one of only a small number of UK businesses that are a City & Guilds Professional Softwash Technician assured.

We offer mechanical and manual removal of the main bulk of any moss and detritus, reducing the need for large amounts of label approved products, with organic products being our preferred choice.  We can then build in a regular maintenance program depending on your product preference, as some clients will choose surface sweeping and manual removal over chemicals.

It is important to note that pressure washing can damage certain surfaces, structures and building fabrics. Equally, harsh and unlicensed chemicals can cause surface damage, but more importantly, environmental damage if they enter standing and flowing bodies of water.

Wild Ground will not under any circumstances use dairy bleach (Sodium Hypochlorite) or other non-approved chemicals to gain instant results and reduce our costs. Our approach is that the environment comes before profits, and we aim to manage your moss problems in the most sustainable way possible.
