My black walnut tree is about 20 years old and for the third time now has grown nuts. I'm in a zone 4a and am wondering what the best way to go about propagating plants from this tree is because I think that it is such a nice addition to the landscape. Should I take cuttings and try to root them or should I try to plant the nuts? Any insight on the methods would be very helpful. I hope that I did not wait to late into the season to ask this question. If pics are necessary just let me know and I could post some. Thank you in advance for any help or insight.
Cuttings won't work. Plant the nuts; bury them about 10cm deep where you want the trees to grow, and put a sheet of chicken wire over the top to stop squirrels from digging them out. After a year or two, clip the wire away so it doesn't strangle the young sapling.
