Nat King Cole notwithstanding, chestnuts roasting on an open fire is a lot less romantic than you'd think. I have multiple chestnut trees. Used to have plum trees. More plums than I needed. Pain in the ass. Plum jam. Prunes. Plum wine. I just let the neighbor kids eat the plums off the front tree and harvested what I could from the back one. Chestnuts are even worse. First off, let me explain chestnuts. The grow in a hull. It's like a kiwi fruit sized porcupine. You just have to wait until the chestnuts fall off the tree. And try not to get stabbed too many times by the dead hulls on the ground.
And chestnuts aren't Christmas. They start dropping early September. So you spend all your free time in September collecting chestnuts. They're a pain in the ass to roast and even after you roast them they don't keep very well. On top of that, chestnut weevils are a thing. They go and lay eggs in chestnuts despite the tree's defenses and so you spend October throwing away, say, 75% of the nuts you collected.
On a related note, I like to think of chestnut weevils as evil and ruining my enjoyment of my chestnut trees, but I must allow that maybe it is *I* who is evil. I mean, chestnut weevils have "chestnut" right in their name. They are much more in the Circle of Life than I am. But I've damned a goodly chunk of this year's larvae to a horrible death by picking the chestnuts and putting them in my concrete basement, where they cannot burrow into the soil and turn into adult weevils to ruin the harvest 2-3 years from now.
