too true about all 3. one thing you may not know, is the impressive protein content of Mulberry leaves especially–up to 28%. this is something that is of great use in a Holistically Managed and/or a Permaculture set-up, because these trees/the foliage can be so easily pollarded or coppiced for animal forage to HUGELY increase nutrition, and avoid feeding them so much legume )which is ok in season, but should never be more than 20-30% of their diets.) also you likely know that humans can also eat the leaves, so that amount of protein and minerals, is super useful in this tree genus, Morus, which is ever so giving for so little effort on our parts.
my question is always which Morus species (alba/rubra/nigra) for Mediterranean zone 9 is best? there is so much conflicting info out there…
