PACE Turf updates in 2022
I’ve been doing some of the updates since spring, and all of them since mid-summer, and I list—below—all the 125 PACE Turf updates so far this year to show you the range of material covered.
If you are already a PACE Turf subscriber, you know about all the information available—the weather data, the climate analyses, the references, clubhouse editions, and the updates.
In 2022 there are topics ranging from algae to zoysia. And that’s just in the updates section. If you are not yet a subscriber, I encourage you to sign up to get access to this information.
