I've already thrown many fertilizer on my lawn. From Compo to ?? - the rest of them, 20 of nearly 30% nitrogen. But what makes this fertilizer from a lawn you just have to have seen. In mid-March I applied the fertilizer and thought after some time? Well, bad buy - because of !! In mid-April was mowing "latest" every 3 days announced. The watchtower of the lawn is as good as other good fertilizers also. But, I've never had such a dense lawn as these fertilizers. It really is as on a carpet. This fertilizer is absolutely recommendable, if it costs a few more. For lawn fetishists a must.
