I am transplanting Iris to an area with crabgrass

Rototilled it 3 times. Do I apply herbicide before or after transplanting Iris.

Answer:

Since Hi-Yield Weed and Grass Stopper with Dimension Herbicide is a pre-emergent herbicide, you should apply this only around established ornamentals. That means that if you are going to transplant ornamentals, you would need to do that first and allow the plants to establish roots before using the Hi-Yield Weed and Grass Stopper with Dimension Herbicide. Per the product label, established iris is tolerant of this herbicide.
