How to Kill Purple Deadnettle
If you have purple deadnettle growing in your lawn, it is a sign that you are not maintaining your lawn right. If you routinely mow (once a week) and fertilize 4-5 times a year, the density of your turf will choke out purple deadnettle. Broad leaf post emergents will take care of purple deadnettle if you apply it in the fall.
