serious case of quack grass

[grass disaster]

a friend of mine has a serious case of quack grass.


he wants it overseeded.

Question: how do i go about doing this.

should i put preemergent on it now then later on in the spring seed... or should i seed now and forget about the pre emergent.

don't put down any pre-m if you are going to reseed! I would also spray the quack grass with round up before seeding.

You might even need to spray Roundup twice. Quack can be very persistent.
