I don't know who fed you that line, but you needn't worry. Olives can
reproduce from seed but rarely beyond the original grove. I've never
seen a volunteer growing more than about 5 feet beyond the dripline and
most of those are the result of ground squirrel activity. We've got a
number of abandoned olive groves in my part of the world (California's
Sacramento Valley) and they never expand beyond the original plantings.
