Isn’t it disgusting how many folks whine about wanting a good lawn, yet they go out and scalp it week after week after week? EVERYBODY says mow high–EVERYBODY! Local newspapers, suburban mailings, all the idiots on the airwaves, and yes, even national magazines!
I think a lot of folks don’t realize that their lawn mowers actually have adjustable wheels! I’m serious. I know these folks want a good lawn–they apply fertilizers a few times a year. They clean the leaves up in the fall. They water in droughts. In addition to scalping their lawn the other huge mistake they make is using a very popular, heavily advertised, nationally well known retail product–that contains the weakest of all crabgrass herbicides–pendimethalin. I saw the bag sitting on the driveway this past spring when this guy was applying it. “Pendy,” as it’s affectionately known in the industry, must be used twice in the spring to get a half-way decent level of crabgrass control. For more information on crabgrass herbicides, go read my older blog You Shouldn’t Have Crabgrass!
It was a WET and WARM spring and summer, which put extra pressure on the crappy herbicides. Scalping the lawn exacerbates the problem, because is supports constant weed germination. There’s a HUGE difference in shade between even a 2 inch mowing height and a 3 inch mowing height. Shaded soil will suppress weed growth much better than sunny soil. Cooler soils (high mowing) will suppress weed seed germination much better than hot soils (scalped lawns).
Here’s another nit-wit. It’s hilarious that these folks are actually WATERING THEIR WEEDS! I’ve labeled the crabgrass seed heads and yellow nutsedge seed heads as a teaching tool.
And finally, I can’t resist taking another swipe at a crappy lawn care company. This lawn has a south facing blend of cool season grass–mostly bluegrass with some turf-type fescue. It’s not mowed as low as the first dolt, but this guy hires a guy with a professional walk behind mower. Because it’s a south facing slope this lawn should be mowed at 4 inches, not the 2.5 inches. This poor guy has a crappy lawncare company and a moron for a mower.
It’s not hard to have a great lawn, folks! Hire a local chain, not the big national ones. Better yet, just do it yourself! Sure, hire someone to mow your lawn it but make sure you read my blog, so that they mow right and edge right!
