Does it always matter what type of fertilizer one applies? Maybe so. Maybe yes. Not sure really sure.
I never used to, but .... from now on, I will promote more core aeration (especially in the fall). During the past 2 or 3 years, most folks around here aerated lawns in August & September when we were still under drought conditions. Hard/dry soil - then only pulling out 1/2 inch plugs. But we always waited until we got rains to allow good plugs -- might be late October or even late November. I aerated my lawn in late November the past 2 years. Plenty of soil moisture, nice plugs, and even the weather was warm (just have to keep an eye on the forcast).
my 2 cents
I remember spreading liquid fertlizer on a lawn that didn't get much water after that... It took several months before the ground was wet enough again... At that time I noticed "Green Patterns" in the turf and realized that the lousy job I did covering with fertilizer was now showing through...
The N in the application was still in the turf,,, it just wasn't being taken up by the plants becuz it was too dry... How much 'volatized' during that dry spell,,, Who knows???
