Today, I went with Guillerme and Rich to spray the crabgrass at Olin College. Crabgrass loves to grow in warm sunny areas and there are plenty of those areas at the college. Along roadways, parking areas and along all of the sidewalks.
We concentrate on the "hot spots" and do a visual check of the interior areas and spot spray any crabgrass we see. I will be using the Permagreen power spreader and the guys will be using backpack tank sprayers.
This year, with all of the cool weather we are having has, reduced the amount of crabgrass and the size of the crabgrass. Usually at this time of year it is quite large, approximately 7-8 inches in diameter and requires multiple spraying to eradicate it. This year we are seeing the crabgrass to be only about 3 inches in diameter max., which is good thing, because it will require only 2 applications to kill it off.
It takes us the full day to cover the entire campus, and we will be back in a few weeks anyways with the next fertilizer application.
