So I've googled just about every possibility for grass decay, I've been taking different routes through my town (not running), planted as many flowers as I could, watered all the flowers over the dead/nonexistent grass. NOTHING IS GROWING BACK??? I even have a cordoned off section (the PWP fenced in area) where I planted flowers and I only stand on the outskirts to water that and now that's decaying too?! What gives?! Now I have so little grass and I don't know what I'm doing wrong and it's freaking me out!! What should I do? Or rather, what CAN I do? 
Any and all help is appreciated!! Thank you!
