brings the lawn in September nor the green

Immediately before an intense rain, I had applied the fertilizer. It dissolves very quickly and evenly. The granules are not so big and not fine. The bucket was enough for my 250sqm.

Be careful: with the iron content should be avoided, to sprinkle Terrassenplatten, since this form the known oxidation stains all costs. Even here, the granules dissolve quickly and therefore deliver a speck.

Otherwise, the fertilizer is reappointed in the next season. For the treatment of large lichens pure iron sulfate is more suitable.
