Response to Hemlock Landscape
Right here in mid-Michigan, we have been very successful using straight urea 40-0-0 (no specific brand) for fall application. We apply granular urea just before we have our irrigation gets winterized, and water it in. We deal with pre-emergent apps in the spring when the Forsythia bloom to control our crabgrass. Our 180+ acres that we maintain is nearly always the first to green up in the spring. I'm no expert, but this has worked for us for many years. Hope this helps.
