my goodness... it's just grass.... last year I overdid the fertilizer in some spots, the grass burned there, what can I say 8 weeks later the spot was green again without doing anything. When the first children, dogs, or other housemates have used the lawn, a bald spot somewhere doesn't matter to you anyway ;) I also wonder how you water the soil if you don't step on the soil.. paddles ([Schneeschuhe]) under your feet and with a finer spray square meter by square meter, otherwise the seeds will wash away on you
