I seeded my yard with scotts turf builder sun mix it contains a 50 50 Perennial ryegrass and Kentucky Bluegrass. I did everything I was supposed to do according to the directions now 10 weeks later I have patchy grass drowned out by thousands of weeds. When I planted it was bare dirt. What I have read is you not supposed to use weed killer until you have mowed the grass 2-4 times. It's not even close for it's first mow. At this point I am worried the weeds are completely drowning out the grass. I want a nice thick lawn with no bare spotts and as is sits right now it doesn't look like I'm going to get that. What should I do to thicken it up and get rid of the weeds? Any suggestions? When I applied the seed I was very generous so it's not due to the lack of seed and I have been watering it consistently. Online I was unable to find anything that talks about weeds and seeding. Any feedback is greatly appreciated. Has anyone else expierenced this?
