Are there yellow patches on your lawn?
Unfortunately, it is hard for an inexperienced person to properly identify the cause of the yellow patches found on a lawn and thus determine the appropriate treatment for the situation. Indeed, these patches can be caused by harsh weather conditions following a freezing or drought period. They can also reflect the presence of grubs, lygus or webworms. Finally, they can simply be the calling card of your neighbourhood dogs.
Given that the treatment will vary depending on the exact cause of the problem, an accurate diagnosis will help you save time and money.
