Hey shelley! Try first cutting your lawn at the highest setting. This starts to "shade out" some of the weeds. Then, water deeply and not very often. THis makes the grass roots go deeper than the weeds normally will be able to go. My husband is still dealing with this, as his MO has been twenty minutes per zone every day. I think the rule is to water J-u-s-t when the leaves begin to curl, and water deeply (put a bucket out and water about an inch). Then, go to the extention office and get a soil kit. Test your soil and amend it (yup, in a thin layer right over top of the grass, compost, chicken manure, whatever, they'll tell you how to do it, depending on what the soil needs) according to the directions the office gives you. You may want to aerate, depending on the age of the lawn, but in general, don't thatch (if I remember correctly). In fact, mulch the grass right back into the grass when you cut it, don't bag the grass you've cut. THis puts nitrogen back into the soil and shades the roots. Amending the soil should help you get rid of some of the strange weeds, as they "crave" certain deficits in the soil. See if all that helps. Organic gardening just did a little piece on organic lawn care...see if you can find it at the library. Also I got a link on this site just this week about organic lawn care in general. If you make the environment for the grass healthier, you should have grass that can outgrow the weeds! Good luck.
