The local one here in Southern Louisiana is the Red Mulberry (Morus Rubra)
its basically a fast-growing weed.
you can cut it to the ground 3 times a season or more, and it comes back every time with vigor.
i use the extra long branches it makes as posts for Muscadine and other vines, or other uses.
every single one i put in the ground grew.
cuttings start very very easily, every time.
i have a dwarf everbearing with similar habits...
- grows fast, cuttings strike easily, and pruning just makes it grow faster.
The difference with the 'red' is the fruit is larger, and its wild locally.
Now that i have Pakistani and Shangri-La and a few others
i will be doing some grafting, and try to get them all on one tree.
i figure the root-stock should be a 'red' , since they are so vigorous, and cutting strike so easily
i figured grafts should take easily also ?
I will be finding out shortly.

if the leaves are turning yellow due to water
you can put cardboard around the trunk in a circle
(keeping it 3 to 4 inches away, not letting it hit the trunk)
and put some mulch on top... it keeps moisture in.
or, you can grow a ground cover the shade the soil....
peanut is a good choice. Peanut is a nitrogen fixer, the nitrogen feeds the tree also.
