There’s a new column on the Nichino Ryokka website. It’s a collaboration between ATC and Nichino Ryokka, with some selected content from the ATC site published in Japanese. The first column is here, and the topic is a 12 point checklist for dealing with creeping bentgrass heat stress (the original list is here).

In addition to the translated content, there will be a few newly commisioned articles on interesting topics. This heat stress checklist is a timely one.

I’ve checked the data from this year and again looked at the average air temperature at Kumagaya in Saitama; at Blackville in South Carolina; and at Avondale in Pennsylvania.

average air temperature 2020 in 3 locations

Those temperatures will put some heat stress on creeping bentgrass. I’d consider the heat stress to be especially intense when the average temperature is above 25 °C.
