Oak acorn drop times
 

Looking for a list of acorn drop times by species. Eastern north america. Im in eastern canada. I have about 20 different types of oaks growing to hopefully avoid failure during late frosts. My problem is i need oaks that drop november or later. My property is crawling with black bears that usually hibernate first week of november. Right noe im looking at nuttall oak, water oak and shumard oak. Anything else? Technically zone 5 but temps lately serm to be fine for zone 6. Any thoughts would be appreciated.
still would appreciate a list or chart of drop times for eastern oaks. I realize it will be different where im further north but should be still relative. I would have thought that would be easy to find but it hasnt been.

Here in WI anything in the red oak family drops them late. In big years, they'll be dropping on top of the snow.

Some of it depends on the weather. How much rain happened and when the killing frosts start.

doesn't matter bears climb them and strip the limbs before they fall

guess i better get used to bear meat as they are breeding quicker than you can shoot them. Thanks

Enjoy, personally I don't care for it, glad I have friends that like it.
