A mate recently gave me a heads up with some growers.. Take an old plant (tree) out the ground, cut everything to sh1t, literally, pot in label it 10 years old wait for shoots and bobs your uncle... maybe this is happening here maybe not. I don't like cheating my 40 plants or more are all grown from my personal seed germination or out the wild as 'infants; not big trees cut and bonsai'd, but what do I know learning as I go. Cheer$;)
