Moss and slime on hard surfaces

Sponsored article

It is well known that certain conditions favour the growth of moss or algae. If you have one or more of these conditions there is certainly a greater chance of ‘greening’

  • Dark, shaded areas – out of direct sunlight
  • Wet or permanently damp surfaces, i.e; poor drainage
  • Humidity
  • Where airflow is reduced, ie; enclosed areas, courtyards, etc

Moss requires moist air to grown and reproduces via spores that attach to the nearest suitable surface. Since the reduction in air pollution, acid rain and sulphur dioxide in the air, moss, algae and lichen has become common everywhere. Often all three suspects are found together; however the small flat, dark spots of lichen are almost impossible to remove without jet washing or blasting.

How to get rid of moss & algae

Although the problem is treatable, unless the conditions in which the moss & algae grew are changed there may be some re-growth and this is where you need to manage customer’s expectations. Where you can it is best advised to chop away any overhanging trees or bushes, improve drainage around edges of mossy patios by digging a small channel and backfilling it with gravel. Removing rotten fences and bushes are also an option that can also serve to improve airflow and reduce the incidents of moss & algae.

There are a number of moss and algae control products on the market but Algoclear Pro is one of the few super concentrated biocides, containing quarternary ammonium compounds. Four times more concentrated than regular products it neutralises the acidity in growing conditions and bonds to treated substrate so that it can keep on working well after spraying. AlgoClear Pro is applied diluted in a pump spray. Suitable for use in a variety of situations such as patios, artificial sports pitches & lawns, tennis courts, timber, vertical cladding and roof tiles - this is a highly versatile product.

AlgoClear Pro in action

Slime on a north facing shed door was sprayed and left for over a year with no subsequent intervention and has kept free of green. The Algoclear works into the wood and any biofilm (greening, slime etc) which tries to attach itself is washed off by natural weathering and rainfall.

Are you automating the aeration process mechanically or manually ? 
Large area or small area ? 
If the clay is deep you need to go down into the clay beyond the root zone therefore hollow tine but a…"

"Horticulture gypsum is an organic mineral. 
Considering a lawn is generally 80-90% of a garden keeping it green, healthy and free from disease is in my opinion, gardening. "

Hi all, hope this is in the correct thread.So i've had some BG86c blower problems recently. Long story short, i've replaced the carb with a genuine Stihl carb as my previous one wasn't priming, everything was fine once replaced but on full throttle…
