I weed, use preemergence and more weeding but can't keep out the dandelions in my Iris bed. Is there a weed killer that I can use in the bed that will not kill my Iris.
|You might be able to very carefully use an herbicide containing glyphosate by wiping it on rather than spraying it. This will eventually translocate to the roots and kill the dandelions. Be very careful to read and follow all of the label instructions and allow it the full time to work. Alternatively, when it is time to refurbish the iris bed and lift and divide all the iris, you could go after the dandelions then.|
