Advice needed - Do parks take care of weeds in white rock landscaping?

Most of our lots have white rock for landscaping. It looks nice except when weeds grow in the white rock.

We spend a ton of time reminding residents to remove the weeds. I’m wondering if it would be easier and less expensive to spray the weeds for the residents who want us to.

  1. California park owners-do you spray the weeds?
  2. Do you have the resident sign something authorizing it?
  3. Do you charge for it?
