How is the best way to kill morning glory weeds in a new lawn?



Morning glory (aka field bindweed) is most responsive to herbicides in the fall when it is taking in nutrients to last through the winter.  Spraying broadleaf herbicides now, when the temperature is above 85 won't work and will do damage to other plants.  Wait till fall and spray your lawn with something that has trimec in it, or states that it will kill bindweed, oxalis and clover.  Put a surfactant in it to make it stay on the foliage.  Also, mow your lawn long during the summer.  A thick, long lawn will help crowd out weeds.
