SAFE Summer Weed control. A golf course superintendent shares his thoughts 

My pleasure. Just happy to help when I can!

Thanks for the feedback and kind words!

@@GregPhillips.22 consider doing some thing on irrigation practices as most people want a set it and forget it philosophy that just doesn’t work with various weather types and drought conditions. Including, but not limited to wedding agents if you support their use on lower cut turf.

I totally agree and it was a goal when I first started. Problems are the warm/cool season grasses thing. I hate to do two videos on the same subject. There are so many differences I could easily do that. Then trying to be sure I get what folks need to make the right decision. Want to be thorough enough so everyone understands so they don't loose grass. First rule is do no harm. It's why I am so conservative in my approach. I do a lot of editing, retakes,notes to keep things moving. I think to leave something out and wonder if that is the one thing folks need to know. I am going to try to do some RU-vid shorts soon. Have tired those in the past and concerned someone takes advice that may not work on their type of grass or their situation. Thanks for the kind words and feedback!!!

It all depends... it can work holding your arm still. If you take a look at my backpack calibration video I'll show you how to see if you're coverage is correct. Basically what you do is put water in your backpack sprayer go out on an asphalt road and spray. Travel about 50 feet then turn around and watch how the water you put on the road evaporates. It all evaporates at the same time you have good coverage. I show it in my video of how to do that. The main thing is overlapping properly and ensuring you're getting the same amount of product out over the given area.

@@GregPhillips.22 thanks so much, I’ll watch that video!

What kind of grass do you have? Happy to help!

@@GregPhillips.22 thank you! It is a mix of cold season grasses: Perennial rye, TTTF, and some KBG.

Thanks for the kind words. I think Celsius in the packets would be your best bet. When it's above 90 do not use a surfactant. That advice is directly from bayer the manufacturer so that would be the best move.

@@GregPhillips.22Thank you for the quick response. I have done one Celsius app mixed with Certainty for sedges about 2 weeks ago with no result on the ivy type weeds so far. I'll wait another week or two and then do Celsius only with no surfactant. The Certainty is showing results on the sedges / Kalinga.

Spectracide makes a hose end weed killer that is safe for St Augustine and Centipede grass it comes in a purple top sprayer

You either get crabgrass early or late. For your region University of Minnesota states before the 3 tiller stage. Likely this will be prior or just after July4th. Or after the 5 tiller stage. Likely that will be after August 15. See UMs publication attached. extension.umn.edu/weeds/crabgrass#herbicide-control-3651661
