The Druids, as far as I am aware, were at their zenith pre Roman times. The Romans did their very best to exterminate the Druids and were pretty successful at it, by all accounts. So perhaps a few thousand or so years ago, the druids may have exterminated mistletoe growing oak trees. I have no idea.
What I do know from long personal experience of farming in Gloucestershire and Herefordshire---- my family still farm down there---- where mistletoe grows almost everywhere in the Severn and Wye valleys on assorted trees and where we still have many fine oak trees that are at least 700 years old, some are considerably older, and my family have been planting oak trees and nurturing them for almost as many years, I have no record, or recollection of mistletoe growing on young, old or even ancient oaks there.
Interestingly we even had a real Druid working on the farm----a nice chap---- I was quite young at the time and could not take the idea that seriously, but the older generation took the Druid thing much more seriously in minor sort of way, but as I suppose, they were Christians of some sort they still gave him considerable respect.
