I'm going to aerate my yard this fall but I have a couple questions about timing and applications.
1) When is it to late to aerate? When is the perfect fall timing (NW MN)
2) I want to over seed an area as well. Should I add the seed before running the aerator?
3) Id like to add a pre-emergent herbicide as well. When should I add this? Same time as aeration? Will this harm the grass seed.
Spell it out for me guys, those three questions.
