I've been fighting a losing battle against my lawn for the last few years. However, I tried mowing high and that seemed to work reasonably well. I fertilize in the fall and spring. I've spent hours pulling out violets, creeping charlie etc. Now, my latest woe is that my lawn this summer has been invaded by another type of grass. Looking on the internet, I think it may be a Bermuda grass, possibly crab grass. It seems to be crowding out all the grass I had, even in areas where it was well established and dense. I'm desperate for any organic solution - can you help?
I have the same problem with lots of weird "grasses" and the violets. I have been pulling them as much as possible but as soon as I take a break from it they come back. I think I have a pH problem. Maybe you do too. Paul Wheaton reccomends having your soil professionally tested. Good luck.
My son, Dane, is gearing up to be in the pH testing biz. He's using my tester. He's gonna do the tests for $5 plus $5 per test. We're trying to put together web pages to describe how to collect the soil sample and all. But if you're in a hurry, you can e-mail him: dane at richsoil.com
Crab grass is an annual. Frost will kill it. The mowing high and infrequent watering will kill of the seed sprouts.
