Iāve never bothered trying to propagate AO (though I did graft an improved variety of AO on some wild seedlings and transplanted them this spring - looking good so far). I have tried, repeatedly, to start goumi from hardwood cuttings and failed. However, the cuttings were from my orchard at my parents place in Houston over the Christmas holidays and goumi never really goes dormant there so that could be part of it. Clark has got me thinking that maybe I should try budding or grafting some onto AO. Suckers may be problematic though.
I think AOs, though invasive, are pretty useful. They fix nitrogen in the soil, are delightfully fragrant in spring, edible fruit (to varying degrees) in fall, and the leaves are a preferred forage. Our goats love them, deer seem to love them. There was even an article in a recent ACRES USA about managing AO for cattle/sheep/goat/deer forage to improve the pasture.
