</font><font color="blue" class="small">( I get the exact results that I got from Chemlawn by doing absolutely nothing. The weeds and english ivy still grow and the lawn looks pretty good but not great. I think once or twice a month they would come by put the little sign in my yard, water it lightly and charge me a bunch of money. I know many people who have considered sueing them because they are such a rip off. At least in my area they don't seem to do anything more than a light watering. )</font>
<font color="black"> We used Chemlawn at the office and I discontinued the service before spring of this year. They had been treating the lawn area by the office for about 10 years and it still had weeds and bare spots. I'm not sure that they hurt the lawn, but this year the lawn doesn't seem to be any worse with NOTHING applied to it.
At home I refuse to use any chemicals on the lawn where the dogs play. We almost lost an Akita about 8 years ago when she walked on the lawn that had been treated with Weed & Feed (the spray kind that you hook to the end of your hose). The Vet who treated her said it happens all the time! People put posoin on their lawns and then let their kids & dogs play on it. Apparently every spring the Vet's office gets a rash of posoinings from fertilizer. As we had a 1 year old baby at the time that all occured, we talked to our pediatrition and he said NEVER to use fertilizer if you have kids. He advocated, very strongly and in no uncertain terms, to use organic controls. I admit that I didn't follow his advice completely, but I use chemicals VERY sparingly. I will only use something like Weed & Feed if the dandelines get really bad. And I don't think I've used it more than 3 times in the past decade. I let the grass grow a little longer and that seems to choke out many of the weeds. There are some organic fertilizers that I have used instead of things like Scotts, KGrow, etc. I won't even consider those things anymore.
From what I can tell, lawns that use chemical fertilizers & pest controls tend to have roots closer to the surface and require MORE water to keep them from burning. Also, I have found numerous organic pest controls to kill grubs, get rid of moles, etc that seem to last far longer and are more effective over a long term (although they may take longer to see results) . . . and none of them will make my kid or dogs sick. Just my 2 bits. </font>
