Maybe they ran out of funds for mulch.
I wonder who is in charge of the garden. They could probably get all of the free mulch they would need from either a local utility company that has to limb trees to protect electrical lines or even from another division of the parks department.
The city of San Jose provides chipped wood mulch to the San Jose Heritage Rose Garden every year. It's good for the garden and the city.
