@chu @teadrinker villages here often have old, much-pruned mulberries in the main square as productive shade.
This thread has just reminded me I had a mission to go grab some of the twigs that get cut-back every winter, to use them for propagation. I may have left it too late. It's a long bike ride to nearest town I know that has them.
Last summer, I was collecting the fruit and the old people smiled and remarked. Those still working generally ignore and the younger people dont even know they're delicious when ripe... because, due to their short shelf-life, they're not marketed as a consumer product.
" #mulberry is a #climacteric #fruit and high ripeness fruits are more susceptible to decay and can infect other healthy fruits, shortening the overall storage period, which causes great problems for fruit traders (Lee and Hwang, 2017)"
