Can I spray Dimension 2EW as a pre-emergent in January and overseed my lawn in April?
I live in the "inner coastal zone" of South Carolina. The only weed problem I am battling is crabgrass. I plan on aerating early April and overseeding my existing lawn followed by fertilizing. My only concern is, if I spray Dimension 2EW in early January as a pre-emergent will it affect my overseeding and will it be effective in controlling early crabgrass?
Yes, you can apply Dimension 2EW in January and then overseed in April as long as you wait a full 90 days between treatments. Overseeding of treated areas within 3 months after a single application of Dimension 2EW, or within 4 months after a split application program may inhibit the establishment of desirable turfgrass.
