How can we get rid of brown spots on grass? How to kill weeds.

Sometimes putting epsom salts on the lawn can help it. We do this on occasion on brown spots.

Pour a glass of beer on the brown spots. It works like a charm. Beer has lots of fermented sugars and nutrients inside it and the dead patch will absorb them and feed the soil underneath. So the beer acts as a fertilizer and if the brown spots are cause by pets it will neutralize the nitrogen in their urine.

I use plain household sugar and Epsom salt to fertilize my lawn and it wonders. Cheaper to buy and no harsh chemicals to deal with. Try it.
