ugh. i would willingly ship u our 60 year old mulberry that is across from my stairs to my apartment; just now its flowers are falling all over my steps, and the bottom and on the side porch... the dogs are tracking them in as they cling to the dogs' fur; they srcunch under our shoes, they attract flies... and soon there will be tons of mulberries, the green/white variety. very sweet, but the fruit is high up since the tree has been pruned as its branches were interfereing with anyone trying to walk on our path to the neighbhorhood... however, it gives great shade, an important factor here, and fast fast grower, and now that i have chickens, well, the fruit will msot likely go to them (the fruit that is fallen, whish is most, some kids manage to climb and get to the fruit on the tree).... also, goats love their leaves, ans in the fall when all the leaves fall off on to my stairs and porch, i shove them in to the chicken yard, the chickens love them, and they are great compost.
i know that here, there are certain varieties and also the male trees that dont fruit so are not a nuisansce unless u want the fruit.
they grow really well here: jerusalem area, arid, high up, rain only some in winter, no rain in summer... cold nights, hot days in summer, cold days and nights in winter. (no real spring or fall).
