How can I get rid of periwinkle in my lawn?
What type of herbicide can I use to kill periwinkle? It has taken over a large part of my lawn, and digging it out is impossible to do it myself.

You can use either Speedzone or Trimec. It is a liquid that you mix with water. Purchase a pump type sprayer and spray it on the lawn, following label directions.
