Killing Weeds With Sugar

Will sugar kill dallisgrass and crabgrass? Is it applied directly or broadcast? Will it kill grass as well as the weeds, and does it need to be watered in after application.

No sugar will not kill weeds. You can use corn gluten in the early spring to help control crabgrass and other types of weeds. If the weeds are not in the middle of the lawn, horticultural vinegar will kill them. But it only kills the top growth, you can however, "wear out" the weeds by repeated application.
