I live in SW Missouri and would like to know the ideal time to aerate/overseed my lawn. I would also like some recommendations on type of turf fescue blend and water schedule for the best seed germination. My yard is about 1/3 shaded, 1/3 shaded/sun and 1/3 full sun. Should I use a different seed type for the different areas of the yard? I have a sprinkler system and plan on renting a core aerator. Thanks in advance for your help!
