We live in Massachusetts and put down a corn gluten pre-emergent weed
control product back on March 19th.

Although the lawn is still dormant, we've noticed some type of weed has
emerged (March 27). Can anyone identify what type of weed it is (URL
to picture is below) and the best way to get rid of it / prevent them
going forward (organic if possible).

Thanks, rw

Looks like Henbit (Lamium amplexicaule), a member of the mint family.
The best time to control Henbit (non-organic) is in the fall with a
postemergence broadleaf control product.

An organic approach would be to pull these weeds now, and mow high
(2.5-3 inches) the rest of the year... pulling the henbit when you see
it. The taller grass should smother the henbit seedlings.

I will be composing an article about Henbit on our website at the
following page: http://www.stockseed.com/weeds_henbit.asp ... look for
it in a few days.
