Acorn size matters


Active Member
I was looking around online to try to find out if an oak that produces a big acorn, much bigger than the normal size of the other Blackjacks in the area, would continue to have the same genetic trait (producing larger acorns). I know it might be environmental but these acorns are 30% larger than any other in the area.
I didn't find anything about that but I did find these study's that both came to the same conclusion that larger acorns means larger sapling. Some times 2-5 times larger in the first 2 years.
Once germinated, the acorn provides the nutrients for the new seedling; makes sense, bigger the food supply, bigger the seedling (on average) ..... ceteris paribus (everything else equal).
That's why you should always plant the largest and freshest acorn you can obtain. A well known chestnut grower in western Illinois sells fresh chestnuts with different sizes and includes a category called specially selected chestnuts for wildlife. When i order from him, I always purchase seeds from his "large size" group. The marginal cost is insignifient; I want that big food supply to give the young trees the best possible start. Just a suggestion.

When I got my chestnuts from Roy this year he had separated them by size and location. I like that so I can see which ones are doing the best for me and report it back to him.
