Clover – Chemical Eradication

Q: Is it possible to chemically eradicate clover in a bed of dwarf iris?

A: My friend Theresa Schrum points out that irises are monocots (single-leafed plants) and therefore should be immune to 2,4-D, the primary ingredient in broadleaf (dicot) weedkillers. However, many products containing 2,4-D are only labeled for lawn application. I suppose you could do a small test plot to see how the irises respond to herbicide application. I have other chemical options for clover control in the landscape at bit.ly/cloveriris.
