How’s this for a lede?
“Hollow-tine coring and solid-tine spiking practices may not alleviate creeping bentgrass summer decline.
Bill Kreuser shared a fascinating update from one of the experiments he is conducting this summer.
I wouldn’t have expected to see such a big difference in growth rate with a mowing height difference of 0.
