Iris Borers

Asked July 27, 2016, 4:19 PM EDT

Just discovered that my iris are infested with borers; they did not bloom well despite lots of buds this spring, and now they have "worms" on the roots, appear to be water-soaked, etc. Can I remove all the plants, treat the soil soon, and still plant new rhizomes before fall? Or what do you suggest? Thank you!~
