Q.Butchered mulberry
A labourer hacked my mum’s non suckering mulberry tree. The tree is about 20 years old, it was cut down about a month ago the remaining stump is about 40 inches. It is Spring here in temperate Auckland New Zealand. The tree has extreme sentimental value as it was gifted by my grandfather.
What are the odds that we will get some new growth? Is there anything we can do to encourage new growth and support recovery?
Thanks for your time and expertise

There are a few things you can do to ensure the tree will come back bbigger than before, but I would not recommend them to anyone who hasn't any previous chemical knowledge. These chemicals are very harsh, and carcinogenic. Now on the bright side, these trees have been known to make some pretty astounding comebacks. Keep the area watered, and you may or may not see new growth. I would say that you will see something start poking out soon.
Here is an article showing how to prune them, and that even a heavily pruned tree can recover: https://www.gardeningknowhow.com/ornamental/trees/fruitless-mulberry/how-to-prune-a-mulberry-tree.htm
