First they will have to be soaked - 4-6 days in warm water. Then the shells need to be scarified before planting.

Check out the linked discussion below for more info. It is about hickory but the process is the same.

You might also check over on the Trees forum here as I recall a discussion about them there earlier in the year that the search should pull up for you.

Good luck.

My I suggest planting those as far away from foot traffic as possible, The sticker balls that fall from the trees aren't any fun. I build a new house back in 2003 at a property that had two mature chestnut trees and they were the first thing I had to have cut down..The trees were not in the correct location and just didn't work, tried racking up the sticker balls and there was 8 wheel barrel fulls and there was still stickers on the ground.

I love to eat chestnuts.
I want to know which season is best for seeding it and Propagate it ??????????
Which country has more growth of chestnuts ????
