Answer: Yellow patches of grass are a worrisome problem for all homeowners, and there are a number of possible causes: insects, chemical or gasoline spills, dog urine, disease, close cutting or poor lawn maintenance, or some of the grass may died over the winter. Yellow patches also occur when the grass becomes dormant during hot weather.
To find the right solution, it is often necessary to use deductive reasoning. No one knows the condition of your lawn better than you do. A daily inspection of the lawn will help you nip any problems in the bud, so you will not have to use pesticides to fight infestations at a late stage when they are more serious.
If your lawn has yellow patches, try pulling the grass up in those areas. If it lifts up like a carpet, grubs may have severed the roots of the grass. If you see birds pecking away on your lawn, a skunk digging, or groundhogs burrowing, check for white grubs before chasing the animals away. There are grub controls available in garden centers, such as Bayer Advanced 24 Hour Grub Control.
