After 2 weeks, well, not much has changed :( Now, after 4 weeks, I have to say the grass grows much closer, and the weed is definitely declined. Especially when I look at the cluster boundary is there a big difference. It Although still present weeds, but overall I guess so 60% to 70% less than before. That's what! The rest I'll stop by hand away.
Will definitely repeat the next spring.
