1. I have a weed in my lawn and in flower beds that has scalloped leaves and white tuberous roots that resemble a Rattlesnake’s rattle. It seems to be taking over, I have tried to pull it up but it keeps coming back. How can I stop this weed?
The weed that you are describing is Florida Betony (Stachys floridana). To control it in your lawn we recommend spraying with Hi-Yield Pre-Emergent Herbicide in mid to late February. One pint will cover 10,900 square feet of lawn (roughly a quarter of an acre). To control it in beds spot treat with Hi-Yield Killzall. Killzall must be sprayed on the leaves to be effective, because it has no soil activity you will be free to plant areas where it has been sprayed. Keep off of the foliage of desirable plants because Killzall will damage whatever it is sprayed on. Florida Betony is difficult to control. You will likely need to spray again in November and next February. Bring us samples of your problem weeds and we will give you the best control strategies for eliminating them.
