Hi,

My name is Sara and I live in London. Im new to this forum and new to
gardening, ive just got a place with a garden, which is mostly decking
- it is covered with nasty green stuff (I think its algae) which is
very tenacious and resists my attemps to kill it off. Ive tried a
scrubbing brush (very labour intensive, took my half a day and sore
knees!)and decking cleaner (only removed a little bit). I think I
might need some sort of high power water jet but I dont know if that
will destroy the decking. Please help!

You could hire a Karcher or similar power washer. Alternatively, you
can buy one in B & Q or similar. They are useful for all sorts of jobs
and will clean up your wood in very little time, provided it is not
rotten.
By the way, there are some strange postings on here, I expected it to
be all about keeping caterpillers off your cauliflowers and there seems
to be a strange thread about the battle of the
classes/sexes/post-menopausal stalkers which I was fascinated to read!

Don't take any notice of the post-menopausal stalkers. I wouldn't say
too much about them though, as they may just try getting you expelled
