This mulberry is great, it is very forgiving and is constantly flowering and setting fruit, even indoors and over winter.
Bought one of these guys on a whim and it has gone through a lot (zone 10a and lots of squirrels). Bounces back every time and is really just the easiest thing to grow. Makes me confident I can grow anything but I think it's really just the plant doing all the work. I've got mine in a huge container but honestly I think I could have gone smaller. I did see berries in less than 6 months since I bought it but unfortunately a squirrel came and mowed the whole thing down. It's regrowing wonderfully and I'm hoping for berries soon!
It arrived in great condition, with young fruit already starting despite the tree's small size. It's already working on a second crop of yummy berries.
