in the season. I started using the Milorganite because of a video by Dan Hansen, he said it was one of the best things to green up daylilies early. I guess that is also where I got the lawn fertilizer recommendation.

Milorganite contains a lot of iron, which can make plants greener, especially if they are low in iron (which is more likely if the pH is high, in which case you wouldn't want to apply lime). For lawn fertilizer a ratio nearer to Fred's would be more appropriate than 20-0-5 unless you know your soil already has a lot of potassium (adequate potassium helps reduce rust severity while excessive nitrogen may increase rust). You really do need a soil test or you're just guessing A soil test doesn't just tell you if something is deficient but also tells you if something is too high and therefore might cause problems.
