Denise from Grand Junction writes

A friend of mine said she used Pin Dee 3.3 T&O Herbicide on her Iris flowers and got rid of the weeds. Is it safe to use on my Iris bed?

Answer:

Pin Dee 3.3 T&O Herbicide is a pre-emergent herbicide labeled to control most annual grasses and broadleaf weeds as they germinate. It will not kill weeds that are already present. It can be used in established landscape ornamentals and gardens. However, this product has been discontinued, so it is not available for purchase from our company. I am not sure if it is still available at other locations in your local area.
