Over a year ago I treated an area with Casoron. I now want to add more top soil and plant hydrangeas. Will it work to peal or rake off a layer of soil, apply the new top soil, dig the planting holes deeper, fill with new soil and then plant the flowers?
If you want to plant in Casoron 4G Herbicide treated areas you would need to just wait one year. After that time nothing is needed, ie removing soil, to be able to plant in the area.
