I received some black walnut nuts at Christmas this year from my brother in law. They were picked this last fall and placed in a five gallon bucket. They have been stored in an unheated garage since (currently -12 degrees). I am planning on planting them in containers this spring and transplanting either next fall or next spring with tubes for protection. Does it pay to plant them after they froze? Is there any danger to planting them where I have apple trees planted? Is there anything special to do with the nuts until I plant them or once I plant them. Thanks for any advice given. Just when I thought I started to understand apple trees a little now these showed up.
