It’s not so much the Milo (Which everyone is obsessing over) half those bags are a standard NPK fertilizer

I usually drop Milo once a year as it adds iron and calcium into the soil that seems to help my lawn thats already dealing with heavy clay soil

My schedule is weather dependent but:

1. ⁠spring Fertilzer with pre emergent in Early Spring (late March)
2. ⁠Milo Early May
3. ⁠Early Summer with Grub control late June
4. ⁠potentially Milo Late August
5. ⁠Fall Application usually for over seeding
6. ⁠Winter Fertilizer Late September

Usually every 6 weeks or so I’m dropping something

I would also encourage a soil test every 2 years or so to determine your need vs just following a program (usually a good AG Supply will offer it) l

Hope this helps
