Last call for crabgrass control. This season got off to a late start so be sure if you have not already, get down an application of Dimension, and then 90 days later do a second application.
Wondering - is it possible to overdo the crabgrass preventer? If I'm using "straight" crabgrass pre-emergent without any fertilizer can I do damage if I use a little extra or do a couple applications close together?
IIRC a product like HALTS has an advisory on the label to not apply more than twice a year.
The problem is that too much pre-emergent may stunt the root growth of 'good' plants. In your case, a little extra or little often (as long as you 'un-catch' up on the timing and don't make it a habit), probably won't hurt.
I would recommend only using a pure crabgrass preventer...no fertilizer.
Go with Dimension, then apply a second application 90 days later.

Thanks - yes, I don't like combining fertilizer with other treatments, especially in early spring - I hate trying to mow grass twice a week when it's constantly raining!
Definitely causes more mowing, but then more fungus issues come summer when using synthetic fertilizer in the spring...I save that for the fall and put down 2-3 applications as that is when you want to be using nitrogen.

Best way to determine when to apply your first application is to keep an eye on soil temperature.

Hard to believe, late April and next week in the mid Atlantic areas, temps in the upper 80s after a colder than average winter....for those that did not get down their crabgrass preventer, crabgrass will definitely be sprouting.
Withinin the next 2-3 weeks, time to put down my second application of Dimension to last me through the summer.
