My honest advice? Keep mowing the weeds, spray roundup to kill everything later in the summer, and start again in the fall. Maybe roundup the current crop earlier then water again to bring up another round of weeds and kill those as well before seeding.

Thanks for the quick reply. To be clear you mean to start over with the seeding later? Sorry just want to make sure. If so, is there a better option instead of roundup to just contain the weeds as the grass is growing?

Yes, start over with the seeding in the fall. Between the weeds and the heat of summer you're probably not going to have much grass left anyway when fall comes.

Weed pressure is going to be much less during fall. If you water during the summer and germinate all that weed seed, then that helps you get a clean canvas for fall. For any weed seed left over, look into spraying Tenacity along with the grass seed - it's a pre-emergent that will allow the fescue or bluegrass to germinate but kill anything else that tries to germinate. Apply starter fertilizer with the seed, it helps with root formation.

Thank you again. Someone recommended seeding with annual rye seed in the meantime until the fall. Any thoughts on that?
