Yeah, Dwarf Mulberry tree = very small fruit. Mine are less than 1/2". But it looks like I will get 3 crops per year.

Thanks for the reassurance... I knew they might not be full size, but 1/2" is about where they are and they are very, very small! I may try repotting and giving it some fresh nutrients, etc. to see if I can eke out just a bit more out of it. Mine seems to fruit constantly from spring through fall, though maybe it's just multiple harvests running into each other. :-)

my dwarf

My dwarf Issai I bought at Logee's produces 1-2 inch fruit from spring - fall. You can see their size next to other berries I’m growing

Nutrients in a container planting do not come from the soil - it doesn't have any (unless you use something like Miracle Gro potting soil that comes with fertilizer additives). Fertilization is addressed by the grower and needs to be done routinely, as it is leached out with the need for frequent irrigation. No fertilizing will result in poor fruit development.

I have a huge tree on my property that produces fruit like this. I’ve been worried to eat it bc I do not know what it is. Is there anything not edible that looks like these berries? Sorry, I don’t mean to hijack but I saw the pictures and it looks just like the fruit on my tree!

amanda take a picture of the tree and a berry and post it for us to see, thanks !

It hasn’t broken dormancy yet but it’s a huge tree. Haha I know you can’t tell anything by this picture. I’ll have to wait until it fruits.

Hi gardengal, thanks for your comment -- agreed, I see repotting and fertilizing as two separate things, but after a few years was inclined to repot in case of any root binding (bounding? Boundedness? Haha) or excessive compaction, etc. I fertilize regularly as it is but was considering altering what I use in case the current products weren't quite meeting all needs... Although judging by the other pictures, it may be right in line with what everyone else is experiencing, more or less. Thank you to everyone for all the input!
