Thanks for your recommendations. I would differ with you a little on Fall fertilizing. My lawn is mostly 'Turf type tall fescue', which is a cool-season variety. I've read that the primary reason for fertilizing cool-season grasses in early fall is that their growth shifts to root development during this time and fertilizer can help this activity.
Well, you ARE one zone warmer, so your turf may get something out of it, whereas I would not in Zone 5. ;)
That’s what I was taught anyway, when I was selling grass seed for a living. ;)
Also - my customer base was ‘The People’s Republik of Madistan’ and ANY nitrogen going into THE LAKES was a no-no, so I can see why fall fertilizing was discouraged. They weren’t too keen on fertilizing your lawn in the spring either, LOL! They even pulled my very favorite 10-18-10 granular lawn fertilizer that I used to use in my garden beds. Terrific stuff.
But, you know - you can’t always get what you want in this world. ;)
