Not really. “Witch” is a pretty broad term. Some witches simply stick to the doctrine of signatures and affect change with direct action (no assist/intercession from non-corporeals).
Some would argue by working with plants/dirts/animals/etc. one is automatically working with “nature spirits”. That’s a matter of opinion. I don’t think it’s the same relationship though.
Personally, I work both ways, but I do find that the herbs and roots I gather for direct action are more useful and effective if they are gathered with deference and respect for the spirit of the place, making a request and leaving an offering.
