Jeyes Fluid or bleach solution


We have severe problems with moss on tarmacadam drive this year. Last
week I tried an experiment. Jeyse Fluid 125ml in 5L as recommended and
applied from a watering can. Then a 20% solution (Not 10% as I tried
before), of Tesco's finest household bleach, applied in a smiliar
fashion.

Both killed the moss but I think the bleach was more effective. It
appears to have killed a wider swathe than the Jeyes Fluid.

In both cases the dead moss will have to be brushed or power washed
away.

On the above basis I will today try the 20% bleach solution in a
pressure spray as I find applying from a watering can to be very
wasteful. ( I had previously tried the same strength Jeyes Fluid but 10%
bleach solution in a pressure sprayer but it was not very effective.)The
10L of mix should go considerably further, cutting down on not only the
cost but the time taken to mix and fill.

This time next week should tell the full story.

Incidentally, whilst I don't mind the small of Jeyes Fluid SWMBO detests
it. Depending on ones attitude this could be a plus or a minus point for
it ;-)
