Dwarf Black Mulberry grafted?

Minky starts with ...
HI I have had a dwarf black mulberry tree (from Daleys - morus nigra) for about three years in a pot and have only recently put it in the ground. Since doing this it is a much happier tree and seems to have a lot more fruit and a lot of strong new branches.
My question is, is this tree grafted as the new branches are below the original branches, and are a lot thicker, stronger and longer (they are the highest branch now) but so far have no fruit. If this is grafted I can't see a graft line on the trunk and should I remove these branches? Thanks for any assistance.

Maybe some plants that are labelled as 'grafted' may actually be grown from cuttings.
the point being that they're vegetatively propagated and therefore a clonal selection.

If you cant see the graft union on the mulberry, you could just cut the new branches off and the tree
should resprout or 'wake up' the buds on the upper portion of the plant and direct growth into them.
it's wanting to grow now , so it will do so anyway it can.

It certainly wouldn't hurt the tree, especially a mullberry.

That's what I'd do, just to be sure.

Hi all

Thanks for your responses. I did contact Daleys and they have told me that the black dwarf is growing from cuttings and that the vigorous branches are probably water shoots that can be removed to keep the framework if I want.

Gabbie - my experience only, but my dwarf mulberry didn't do much for two years while in a pot (I was also probably a little neglectful with watering though). Once I put it in the ground it has improved out of sight. Your choice though.
