That was no gardener ... could possibly have been one of the groundsmen who massacred the gardens where I used to work ........ but a gardener............ not in a million years.
Give it a feed of chicken manure pellets and water them in ... the nitrogen will encourage new growth from the base. Then when it's tall enough to screen what you want get the chap back and get him to carefully cut out the old stems from the base. That'll larn him.
On the plus side, you should get some good bamboo poles ... do you grow runner beans ?
