Mushrooms and Ants in my lawn
We live in Michigan and have been battling our new front lawn for two years. The soil is sandy and we added top soil and planted seed. Grass has started to grow and then we faced all kinds of weeds. We have attempted to kill the weeds and were planning on overseeding in late summer but now we have tiny mushrooms growing on one side of the lawn and small ant hills on the other! How do we get ride of these and keep our lawn growing.

The mushrooms are simply an indication that there is organic matter in the soil that is breaking down. The mushrooms feed on the organic matter, and form fruiting structures when conditions are moist. As it dries out this summer, the fruiting structures of the mushrooms will go away. In the meantime, if you'd like to break them off with a rake  you can do so. There is no effective fungicide to get rid of them.

Similarly, ants in the lawn usually cause no damage to the lawn, so they don't need to be controlled. If you'd like, you can apply ant killer directly to their mounds, but keep in mind that doing so will kill beneficial insects as well.
