Moss on courts

Has anyone had a problem with moss on their courts, and managed to resolve it?

Our favourite court has got increasingly mossy at the corners and sides and it's spreading into the middle now. On dry days it's not a problem, but when it's wet it can be quite slippery.

We tried using a few bottles of regular moss killer from a popular DIY store, but I reckon we'd need a LOT more than a few bottles to do it properly as it didn't really have any effect.

Has anyone had any success themselves? Or hired a company to do it? Or managed to get their council to pay?

Urea pearls, the kind used for thawing pavements, will kill the moss within a few weeks and should last til next winter. You can get a nice even spread if you use a lawn spreader, its not easy doing it by hand or shovel.

to save the planet use elbow grease and not chemicals

It's a public court so we couldn't really leave stuff on the ground for weeks at a time.

Elbow grease would be fine (we have 10+ players who could graft) but I don't think it would be effective. It's not deep moss you can scrape off; more like little bits of hardly-visible stuff that sits in all the surface imperfections.

We're getting a bit of that in Manchester too. Thought about chemicals, but just using stiff brushes seems to have got rid of some of it while we were clearing leaves the other night.

Well, we do play in Moss side.

Pressure washer

Make sure the ground is wet, then the urea dissolves very quickly

So piss on it? I can do that.

It would take a lot. Maybe if you bottled it up for this time next year? You should look into a catheter adaptor for your Camelbak, don't want to get caught short

Thankfully I keep all my piss.

you mean you don't drink it ?

i hear the '79 vintage is a doozy

Tried using chlorine?

Chlorine Bleach Moss Killer Recipe
5% – 10% Chlorine Bleach
90% – 95% Water

I don't think bleach is damaging enough to the environment, why don't you pour acid all over it, then resurface it, once a week. #jesus

What about DOT hydraulic fluid?

Yeah, maybe mix some of that with some hydrofluoric acid. Then garnish with some acetone.

Take a deep breath and then wash it off with blood from cows with foot and mouth.

Oh no! sorry to hear that highgate is now bryophytic...

Don't think it is that damaging at all:

Environmental effect of chlorine**

Chlorine dissolves when mixed with water. It can also escape from water and enter air under certain conditions. Most direct releases of chlorine to the environment are to air and to surface water.

Once in air or in water, chlorine reacts with other chemicals. It combines with inorganic material in water to form chloride salts, and with organic material in water to form chlorinated organic chemicals.

Because of its reactivity chlorine is not likely to move through the ground and enter groundwater.

Plants and animals are not likely to store chlorine. However, laboratory studies show that repeat exposure to chlorine in air can affect the immune system, the blood, the heart, and the respiratory system of animals.

Chlorine causes environmental harm at low levels. Chlorine is especially harmful to organisms living in water and in soil.

I refer you all to post #7...

Firstly, I'm super impressed that people actually care about the environment! Next we'll be saying that we don't want global sportswear brands involved with bike polo...

There are two types of bleach. Chlorine bleach is a pretty toxic to the environment, so I really wouldn't recommend this. However you can also get oxygen bleach, which (if I remember correctly) breaks down into water, oxygen and some sort of harmless salt. You should be able to get this from a garden centre in the decking area. This, a bucket of water , a couple of stiff yard brushes and half an hour of scrubbing should make a difference.

Or you could just get a power washer.. (see post #7)

Manx twat, according to my first passport!
