Sorry if this has been posted before I tried the search and kept coming up with "Fatal Error" message. I have a large lawn that has a lot of high and low spots caused by Winter and not being that flat to start with. I thought this Spring I would core aerate a couple of times to loosen the soil and then roll to help flatten it out. Leave it for the Summer then do it again in the fall. Does this sound like the correct solution or is there a better way to flatten out a large area. I not looking for a pool table just trying to get rid of all the bumps. Thanks for any help !!
