Real advice on Lawn care !
About watering your lawn
Well I like to keep things simple the best way to tell if your grass needs to be watered is by going to a couple spots on your lawn and see if the soil is dry. Its that simple , grass dosent like to be soaking wet but it doesent like to be dry either.
And the more fertilizier you use the more you need to water
Grass loves food ! but in the proper amounts at the right times
Fertilizing should be done as soon as the snow melts. It should be done lighter amounts then suggested. You are trying to promote healthy growth, not a super crop of super fast growing grass. You should only be getting an inch or two of growth a week.
