Our lawn ca.500qm was full of clover and various other herb stuff. Spread I have let it be due to a rain-free day and 2 days. Then I sprinkled vigorously. This is now a week ago. The clover is completely gone only remnants of dandelion can be seen, I can live with'll sprinkle it again. The lawn now shoots out of the ground that you have to mow or mulch 2 times a week. And it just looks cool.
Strong buy recommendation with a minus star for the high price.
