It depends a lot on what type of mulberry it is, but I'm assuming it's a fruiting variety, many of which are smaller than the species.

In any event, as with other trees, summer pruning should be the best way to keep it small. You might even get a small second crop of berries as a result of this.

It is fruiting. I have a larger one here that does not set fruit, a couple smaller ones that will be cut down that haven't set fruit and this one. This is the only one that has fruit. I'd like to try to keep it. I'm thinking of pruning it soon if it won't cause too much damage to the tree. We just had a very large elm removed and now I can get to the mulberry and work on it.

Prune them like hell. You can stub them back or train them to a weep, but prune them a couple of times during the growing season and you can keep them in bounds. They bear on same year wood so as long as you keep smaller pieces of wood regenerating they can bear well no matter how you prune them.

Thank you harvestman,
I will be out there pruning this baby up.

Here's a photo of my 3 year old, 4 1/2 ft, Illinois Everbearing Mulberry. It has about 100 berries on it. String and stacks in the ground are bending the branches and the center leader has been removed. Light weights on the grow tips can help shape growth also. If at some point it gets out of control I'll just start a new one. They grow and produce fast.
