While visiting theUS cemetery in Normandy, France, I picked up three acorns. I’d like to plant them this week. how deep? Should I move their container outside now, or after they sprout? Should I put the acorns in the refrigerator or freezer first?

Charles, if you just got them off the ground,, they should be be cold stratified and ready to plant. Bury the acorns about twice their length, in good soil, outside now. Keep the soil moist, but not overly wet.

And use some kind of critter fencing or guards. The squirrels will want them

Charles thats pretty cool. I sure hope they do well.

then tube the tree, I have done many this way

Charles, just out of curiosity, do you happen to know what variety of oak it is? I've no idea what they have over there.

Probably against the law to bring them here. Just sayin'.

Unless they are declared, and have been treated.

Do you really want to plant what could be considered an invasive plant? Lotsa history on that sort of thing…good and bad.

People grieving our lost heroes at the American Cemetery in Normandy intentionally planted American Red Oaks there. It's pretty well known and mentioned in a lot of documentaries on Normandy. There are other types of oaks in the area. The fact the acorns hadn't sprouted yet makes it very likely they are American red oaks.

There's dozens of species of foreign oaks in the US already. The only species considered invasive by some people is the Sawtooth Oak, which many people plant for deer and other wildlife.
