Flowerbed fence

Plants have been planted at the intersection of Verseny Street and Jobbágy Street on several occasions, which we were very happy about, as Verseny Street is a fairly barren area. However, unfortunately, since it is not surrounded by a fence, people often walk over it and use the area for other functions (garbage bin, toilet). It would be great if these plants could survive this time and the area could remain greener. Thank you very much in advance for your help!
