Lawn care - Knowledgebase Question

My lawn has developed large brown areas. It appeared to be lack of water but when I dug up a patch it appears that there is plenty of water. In fact I may have overwatered to rectify the problem. I recently fertilized with Scotts turf builder. I'm at a loss as to what to do. Help. Should I take a patch to my local Home Depot?

When you dug up the patch, how did the roots look? Brown patches can be the result of insect feeding (grubs will consume the roots) or compacted soils can keep roots from getting adequate water - or compacted soils can make water puddle which can suffocate the roots. Fungal diseases can also cause brown patches in the lawn. closely inspect the grass blades for fungal spores. Once you've confirmed or ruled these problems out, there's just one more consideration. There are both warm season and cool season grasses. Warm season grasses begin to green up in April or May, at about the time cool season grasses begin to go dormant. Then as the weather changes in September and October, warm season grasses go dormant and cool season grasses begin to green up. Could it be that you have patches of cool season grasses that die out in the summer? Hope this information helps you determine just what the problem might be. Best wishes with your lawn.
