Seedlings treated with Dimension at 23 days old and about 3 inches tall were not injured. Sept 2011.

I think it may be possible to treat new grass with Dimension if you can get it up to 3 inches tall before treatment. I hope to try this this year. Clearly there is a narrow window of time when the new grass is 3 inches and yet crabgrass has not yet germinated. I think the label says the new grass must be well-established. You must accept some risk.

If anybody tries this let us know what happens.
I am worried about the dimension hurting the seeds before they have a chance to germinate.
