I will not know anything until the spring.
I am waiting to see if the Preen product I bought last Fall and spread it on the entire alley really works for 60 days on the label.

Nice application
Would RecommendWe just purchased this to tackle the weed problem in our backyard. Landscaper said to sprinkle this on to avoid future weeds. We only applied it once so far. Application process is easy to do and easy to follow from the written instruction. Results are TBD.
