With overlapping generations, there will always be elders to pass along such things as agricultural information. That has worked very well on the coast of British Columbia for the past 14,500 years, that we know of (Heiltsuk oral history, now confirmed by archaeology.). "Indian Time" is still prevalent here. The Neolithic has never been completely eradicated by the scourge of European influence. Culturally, it's so profoundly different and nice to see. My housekeeper is Haida. My gardener is Cree. If my land was a lot wetter/lower, I'd want to transplant our big ferns for the crozers, the fiddle heads in the spring. You only pick one or maybe 2 from each plant, acres of them. As they mature, we just go up in altitude where spring is later and the ferns are not so developed.
