Fertilizer causes a very good result. Strong grass growth but only in conjunction with a very good grass seeds Wolf. Mention should also find that there are more seeds are required as in the instructions given by Wolf. Have the lawn fertilizer in conjunction with a Wolf - spread seeds and a Spreader. Here I have but increased after a short time, the setting on Gritter contrary to the requirements. After the grass had cast in late summer, the difference in the scattering surfaces was clearly visible. Danger is here but certainly an over-fertilization!
