Is it necessary to prune Fruitless Mulberry tree?

Question

Is it necessary to prune a Fruitless Mulberry annually? Mine has been pruned each year and has the round knobs at the end of each limb. I am too old to do it myself and really cannot afford the $100 charge to have it done each year. But I have been told that it must be pruned each year.

Answer 1

As this article explains, trees like yours that have been pollarded (forming the round knobs at the end of limbs) do need to be pruned every other year at least:

A tree that was previously pollarded and then not pruned for years could become overgrown and need more expensive maintenance later:
