I've moved to a new house. I dug up and trashed Foxglove plants because I believe they're toxic. Do I need to dig up all the roots? And How long should I wait to plant an edible (Sage) in that soil/area? Thank you.

Yes, Foxglove is indeed toxic, according to Cornell University. You can learn more about it here:

I was not able to find any research indicating whether or not its toxic compounds could linger in the soil after it is removed, and be taken up by edible plants in the area.

According to UC Davis Weed Research and Information Center, mechanical removal (like digging out the entire plant and roots) is the best way to control foxglove. You can download a PDF from UC Davis with more details by visiting then entering "digitalis" in the search field on the left.
