How long does the acorns take to sour or rot. Once they fall off the tree?

Are you trying to store them and replant? Storage life is about 4 months.

Depends on what kind of oak tree it came off of. I don't remember specifics but different acorns have different levels of tannins, higher tannin acorns usually take longer to germinate so they last a lot longer.

White oaks are preferred by deer - less tannins , germinate quicker. Red oaks have more tannins and last longer, don't germinate until spring

Correct, white oak acorns have low tannin levels, therefore they are more palatable to wildlife, as well as they will sour quicker. While red oak acorns have higher levels of tannin, so while they don’t typically taste as good, they will last much longer on the ground.

If you are talking about collecting in hopes to plant it this coming spring, the ones that have been on the ground for weeks are probably no good. When acorns hit the ground, there is a high chance they get eaten by deer, squirrels, or even insects. If you see a hole in an acorn, even a very small hole, insects have gotten into it and it’s no good to plant.

If you want to collect to plant, it’s best to look between late September-approx. early November when trees are actively dropping.

With that being said, this has been an absurd year as far as acorns go. I know of shumards that are still green currently and dropping still. That should all be done after the weather this weekend.

If you are looking to collect and plant, just perform a float test on them and that will tell you if they’re still good or not.
