Bereaved families in St Albans have received a letter from the council warning them not to exceed new limits on where to place flowers on graves.
The letter says any grave at London Road Cemetery which has been there for more than a year should not have tributes outside an area of one foot, by four foot six.
Residents say that there have been no problems with burial sites, and many are upset about having to reorganise the graves of loved ones.
