Drooping Mulberry Tree

Question

Why is my Mulberry tree drooping? It was repotted last year and began to grow like crazy from a small 2m bush. The branches were strong. It lost its leaves in Winter and then sprouted new ones. It is now carrying about 500 new mulberries but for the last few weeks it is drooping. I understand the obvious answer would be too many leaves, too much fruit, but it has had this for some time without drooping. Its only recently that it appears to be unable to support itself. I don’t believe it is the leaves or the fruit, the whole tree just seems to be limp.

Answer 1

That didn't go out correctly. I meant:
"...It was repotted last year and began to grow like crazy from a small 1m twig to a 2m bush.
