I'm just a customer, but a lawn service messed up (for all I can tell), and I wonder what can reasonably be expected to fix the situation. Our neighbors' lawn service mistakenly treated my lawn instead of my neighbors'. I know it was just a mistake, but I might as well put it as: they entered my property without authorization and spread chemicals I didn't order or want. Well, they checked the "needs overseeding" box on the slip (hey, at least I didn't have to pay for it), but spread "25-0-3 Fertilizer with crabgrass control (Barricade .29%, 4lbs/1000 sq ft). Now for all I can tell, overseeding isn't possible for the next couple of months, but my lawn was newly seeded too late last year, most of it didn't make it, and I was planning to reseed it soon. I surely don't want to be left with this all summer: For one thing, how could they apply a pre-m for a lawn which so obviously needs over-/reseeding??? But more importantly, what can be done about it now, and what can I reasonably expect them to do? I suppose laying sod on top of the pre-m'ed soil should work, but then I strongly doubt the lawn service would pay for that to make up for their mistake (and I'm not going to pay for that, either). But in my opinion, they messed it up, they need to do something about it -- what?
