[quote=nelli]Hello everyone

I hope that you can help me
I need to find out urgetnly how long does the moss grow - the usual moss that grows on the roofs and for what period
I searched all over the internet but I could find the info. the only thing I`ve found was that moss can grow 4-6 inches, but it didn`t say for what period of time?

Please help

We had a roof covered in moss years ago before it got knocked (asbestos) down and it always looked the same length around 2-3 inch that roof was probably there for 20 years. There are hundreds of varieties of moss though and I bet there’s some Amazon rain forest moss that grows a foot long. Turf moss however usually stays under an inch.
