thank you, well im a bit far from you to recieve cuttings plus its also impossible as im actualy in fact on a island called new zealand, in the great southern hemisphere, im originally from south africa and we as kids absolutly love the tree in raiding it for fruit and leaves for silkworm raising, new zealand has morus alba but only in the form of the weaping white mulberry, and they rare and few inbetween, but seeds i can get of the large variety but only in seed form, hence my enthusiasm to grow from seed, i love a challenge hahaha, but good note on the digestive tracts of birds, maybe scarification could do the tick as i think thats what the gizzards of birds do, plus warm and cold stratification. will try to get cuttings from a large morus nigra down the road and see if it works.
