I started using Millorganite last year because of all of the good feedback on it and plan on using it again this year. I saw a person mention Pennington pre-emergent. Any other recommendations for just pre-emergent?
I like Milorganite but it is super expensive now that it got super popular, when you compare the nitrogen content to synthetic fertilizers. Keep in mind that the typical analysis on milorganite is like 6-4-0. That means you're lawn can eventually build up too much phosphorus over the course of a couple seasons. There are other issues with excess phosphorus getting into our waterways. If you've been using it more than two seasons, I'd recommend a soil test to check levels. Some county extension offices will do a simple soil test for very little money or sometimes free.
