Ontario has recently banned the use of herbicides for domestic use. There is a product called Weed Prevent whick killes the seeds but not actively growing weeds. Is there anything that can be used to control weeds (other than the old fashioned was of pulling them by hand). Jim

I'm not specifically familiar with your regulations, but there is one weed preventer that is considered "natural" that sometimes passes muster when others are banned. It's called corn gluten and there are several brands on the market  in the U.S. and (at least formerly) in Canada. Check for that. It it's not allowed, you don't really have any options, other than keeping your grass as tall and thick and healthy as possible, which will reduce -- not eliminate -- the weeds. Then pull by hand as much as you can.
