The City of Cape Town’s Recreation and Parks Department advises the public that it will commence its mowing schedule at parks and public open spaces at the end of November 2022, to allow for spring flowers and a variety of indigenous plants to bloom – not just for aesthetic appeal, but also in aid of conservation.
The City's Recreation and Parks Department has adopted a 'no mowing' position during late winter and early spring.

Residents can apply for their community park or portions of green spaces in their area to be added to the list.
Email RP.Enquiries@capetown.gov.za with the location, some evidence of the flowers and support from neighbours living in close proximity to the area.
If your park or green belt is a now mow zone, but does not yet feature in this project, tell us below.
