Now is also a good time to apply an application for grub control. Optional, yet recommended to avoid potential lawn damage. Merit is a good product to use. If you have moles this product will also help, as it kills off their food source. Grubs can do a lot of damage to a lawn. Usually it’s not so much the insects, but rather the rodents that eat the grubs. I.g moles which tunnel under the sod and raccoons which will pull up the turf. Raccoons usually do the most damage. Often times just overnight. Apply around April / May.
