Aerating - almost time !
""The 2 best times to aerate your lawn are the spring and the fall. I have a personal opinion that the fall aeration works better than the spring." The reason why you aerate in the Spring and in the Fall, is because this is when the ground is the softest. Also it is a great time of year for fertilizing and over seeding your lawn which work best with aeration. Unlike the previous comment, I think Aerating works best in the Spring. This is because clay soils get compacted in the summer when it gets hot and this puts a lot of stress of the roots. If you aerate your lawn in the Spring you can actually prevent this from happening. (The most popular weeks nation wide are the second and third weeks of April. October is also a popular month!)
