Did according to the instruction we seeing weed are popping this morning. we got rain past 2 day in the area, so far has not live up to what suppose to take care of all those type of weed.
This Is the 1st time I've used Anderson's barricade.I put it down and got an inch of rain 2 days later. Have not seen any crab grass or other weeds that I normally have in the spring . I am very happy with this product.
