Afew years ago, the EU (in their infinite wisdom?) decided that those excellent moss killers we used to use, which contained Dichlorophen, should be banned.
Now some of the moss killers are “organic” – but isn’t moss??? There are 5 different types of moss that thrive on tennis courts. Four of these preferring to start growth underneath the grains of macadam, which of course is detrimental to the court surface.
Richard spent one winter testing every major moss killer on the market (organic included!!), until he found one that suited his tennis court needs.
To this end, it was found that the moss killer has to be applied in a certain way. The court surface must be wetted sufficiently with the product to allow it to soak around each grain. The use of light sprays will not be quite as efficient.
After the moss has been killed, it MUST be washed off the court. Leaving it to Nature (as some manufacturers recommend), will NOT work, since the dead moss is blocking the pores of the macadam which will affect the drainage.
If the court has been thoroughly cleaned, the application of a moss killer thereafter will only act as a preventative – hence no more moss – ever!!
