Some of the new broadleaf weed control products do a good job on non-grassy weeds... An important thing to do is get a soil test... You may have some sort of soil deficiency that is allowing those weeds to prosper.... Working on your soil health will help produce a wonderful yard... Last is watering habit.... Deep and infrequent watering tends to encourage Grass and the few deep rooted weeds while Frequent shallow watering encourages lots and lots of shallow rooted weeds... One comment... Some folks hate clover... Some folks love clover... It's a free source of Nitrogen that feeds your lawn... Historically, most grass seed was 25% clover so that you wouldn't have to fertilize... If you do get rid of it -- you will have to make up by adding that much more Fertilizer... Thanks John

I have a patch of white clover in my yard that I planted about 25 years ago. The soil is sandy. I don't remember the details of the planting, but I do remember that I broadcast the seeds by hand and lightly raked them in with a leaf rake. This clover is very well established and is the dominant plant in an area of about 300 SF.

As a rule the White Dutch Clover that grows best in lawns grows there because of lack of adequate levels of Nitrogen in the soil. When I was growing up people would seed the WDC into their lawns for that reason. If you do not want it there the first thing to do is get a good, reliable soil test to see where the other major nutrients are (Soil Nitrogen most likely will not be tested) so you can make a reasonably intelligent assessment of what that soil needs to grow a healthy lawn free of the Clover.

Picture #1: If you think that dead spot is from a dog, scatter some table sugar on the area. I've never seen a spot that big from dogs, so I'm not sure what the rate would be. Excess sugar is harmless, so I'd probably put 'several' cups of sugar on that area. Moisten afterwards, but don't wash it away. Give that 3 weeks before you do anything else in that area. The grass might come right back. If it does, it will be greener and faster growing that the adjacent grass. Sugar is not a fertilizer, but it will stimulate the microbes in the soil to go into mass production of organic fertilizer. Picture #2: Yes that was clover and yes, the herbicide kicked in. Although I've never seen Dutch white clover that did not have a white shadow ring through the middle of the leaves...like this. In any case, it's going away soon. Picture #3: If you decide to reseed that area, I would do a full renovation. Oops! I just remembered something about RoundUp from your initial post. I guess you can't do what I was going to suggest. The renovation approach I like involves two rounds of Round Up, one week apart with lots of shallow watering during the process. If you don't like glyphosate then that's out. So instead, tell me about your watering schedule. How often and for how long do you water the lawn? I think I'm going to suggest a change to that and see what happens.
