Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Water irises, too much of a good thing

One of the better low volume to purchase herbicides (1 gallon size abt $32-35) that will work on iris and many other emergent shorline plants is called Shoreklear-Plus. It is glysophate based with a surfactant included. Dilute and spray. You may have to spray several times up to 2 yrs later to get everything killed that you want killed. Spray some this September and see what sprouts next April-May. Spray again before or during flowering. The iris may stay relatively green most the the year if sprayed in May. Although few of those regrow the next spring from my experience. I'm in the process of getting rid of all my yellow water iris. As you learned they are too aggressive for a smaller pond where one could do better to have other slower and shorter growing emerent shoreline plants.
