Hi, can anyone help please?

I've tried the FAQ for this ng at
(http://www.tmac.clara.co.uk/urgring/urgfaqs.htm)regarding lawns but
it doesn't really address my situation. First, I am not a gardener,
I'm truly a novice at this so please excuse my ignorance.

I've had my garden landscaped recently with a new circular lawn. It
looks fantastic. What I'm after is recommendations for a book(s) or
online resources that can tell me how to maintain the lawn and to
advise on the type of lawnmower I should purchase. For the record, the
lawn has a diameter of 8 metres - just in case this has any bearing on
the kind of mower I should get. I've been told that a small electric
cylinder mower with a heavy roller is probably the best.

Any advice would be most appreciated.

Cheers,
Simon
