What is it up there that requires Celcius??
I haven't used it yet, because what I am having problems with requires Certainty!
I hit preemerge two weeks ago with vessel and coron for uptake........slightly yellowed out both types of grasses. Thank goodness for the Issac rains and the other rain last week.
All week the lawns have grown 45% more than before the storms. Dang!! This week we busted our butts after the holiday!!
