I'll have to say that I'm somewhat lucky as I seem to not get hardly any weeds during the off season. The few little bits I do get I pull out asap so that it doesn't spread.
I've always been of the opinion the less chemicals you can use the better your lawn will be for it.
Cheers, BB.
I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
