Moss treatment if using crabgrass pre-emergent

[Howard Canning]

Hi,
I want to prevent crabgrass growing on my lawn and I understand now is the time to do it. (4/23). I was going to use https://low.es/2Kws6ki but I also have a new outbreak of moss on my lawn under trees. Should I apply pre-emergent first or treat the moss first or how would you schedule it. Also when should I aerate and lime? Is there a sequence this should all be done.
I'm in Massachusetts USA and use a RYE and Bluegrass seed blend. 1/3 acre lawn.
Thanks.

Have you had a soil test taken yet?

It is irresponsible to advise gardeners and other plant enthusiasts to apply any chemical, without regard to soil conditions, plant needs, and environmental health. Sounds like you may have soil pH issues and that's why its important to get a soil test and be sure before adding any chemicals.
