How early do you aerate?

How early do some of you do your spring aeration? I'm going to put down some 19-0-6 with Dimension sometime this week. If it is dry enough would it be ok to go ahead and aerate now are should I wait until the grass is about to start growing?

Without getting into a long technical explanation (which has beeen done here before) it is not beneficial to aerate a lawn unless it is actively growing.
There is no microbial activity, no root growth, no photosynthesis taking place, oh there I go.
I'd wait until it starts to grow. Good Luck

Actually, how late? I don't do any spring aerations. I rather save that service for the fall for overseeding. I am too worried about preventing crabgrass in the spring to deal with seeding.

I wouldn't put any pre-m down until after you've aerated, all you're doing is punching holes in the barrier. Is there a reason why you are putting Dimension down so early?

I would have to agree with Lbilawncare. When you pull a plug out of the soil, you'll pull up weed seeds too. if you pre-m before you aerate, you;ll have just as many weeds coming up as if you hadn't pre-m'ed at all.

According to the Un. of Georgia turf managment course I'm taking aerating doesn't have a significant affect on pre-m. Dethatching does dut aerating doesn't.

There is nothing wrong with aerating in the spring. It is best in the fall, but some people like to have their lawns aerated twice a year. I would take the others advice and wait and apply your Pre-M after you aerate. I would also wait untill the lawn is actively growing.

If the lawn is weedy, I would wait untill you get them under control and aerate in the fall.
