I put down some crabgrass inhibitor earlier this year and so far uor lawn has looked "great". It's really not great but it is compared to last year. I put it down on May 19th and it's supposed to work for 3months. I guess that time is nearly up and you can tell because now there are all sorts of weeds growing up through the lawn. Looks like I will be spending some hours out there today plucking what I can. My question is, can weeds grow at any time? I thought the idea of the inhibitor is to stop weeds (I should say crabgrass) germinating at the time of year when they typically germinate thus preventing them altogether. It appears as though I have simply delayed their coming by a few weeks. Is that other people's experience too? I know that building a strong lawn takes a a looooong time. Our is patchy and needs reseeded but I can't do that until the fall now. I'm hoping that we have a thicker, fuller, stronger lawn over the coming years.
