Ware is Milo part of your regimen as well?
Not exclusively, but yes I use it a lot. It's definitely not the most cost effective source of N, but for me some of the benefits outweigh the cost for a lawn the size of mine.
I really like the even/thorough coverage I can get when using lower N content products. For example, I can easily spread two 50 lb bags of Greens Grade Milo over my 7k lawn in two directions to get a modest ~0.85 lb of N. With something like a 32-x-x, I would only spread 18.6 lbs of product to get that same amount of N. Depending on the SGN, I'm not sure my spreader would feed that consistently if I reduced the setting enough to spread it in two directions.
I like that I can work with full bag quantities, even on my smaller lawn. I can use 1-2 50 lb bags of Greens Grade, or 2-3 36 lb bags of standard Milo to tune my N rate without weighing product or dealing with leftover or partial bags.
I also really like how easily the SGN 90 Greens Grade Milo flows from my spreader and falls down into my dense turf canopy.
The recent reduction in Fe from 4% to 2.5% bothers me a little, but I probably won't stop using it.
Milo breaks down with heat not water like other ferts. That's why you don't need to water in and it works better with higher temps.
But worth noting that 2.5% of the 6% total N in Milo (~42%) is water soluble. So like Redtenchu, I've never had any trouble getting some response within a week following application.
