In this video I take some time to try and simplify the concept of growing degree days and how that helps you understand when you should re-apply plant growth regulator. There is a lot of information out there on what PGRs do and how you should apply them; however, I had not seen much information around when you apply them again beyond it being referenced in passing in a few videos. This information is hopefully helpful in establishing an interval that you should re-apply your PGR to avoid any sort of growth rebound, where the turf actually grows at a rate higher than it did prior to the PGR application for a period of time.
