Q. I planted horseherb like you suggested and it was doing great, last week put corn gluton meal on it to fertilize and now it is all almost dead, was it wrong to put it on, I thought it was a fertilizer?
A. Although this native groundcover has very low fertility requirements, corn gluten meal shouldn't hurt it unless overused. On the other hand, you may have come up with a new broadleaf herbicide.
