Maggie Reiter joined me to discuss how the start (and end) of the turfgrass maintenance season might be predicted. When is spring green-up? When does the season end?

• We discussed, and showed charts of growth potential and temperature, from this post: https://www.asianturfgrass.com/post/maps-of-average-temperatures-in-the-usa/
• The Sunday Lawn Care plans
• We discussed the article "An examination of turfgrass species use on golf course putting greens" by Brosnan et al., which you can read, and see the maps of species use, at: https://doi.org/10.1002/cft2.20160

I discuss small plot university research with fixed treatments vs. golf course and sports turf maintenance with treatments that vary, and consider which results we should trust more. I also discuss the bobble test after 270 rounds, mention that core sweepers are a nice machine, and explain how I estimate N harvested in creeping bentgrass clippings.
