Lusaka City Council (LCC) has advised residents to stop planting umbrella trees, also known as Melia azedarach, along roads, pavements, driveways, and other road infrastructure within the city.
Council Public Relations Manager, Chola Mwamba explained that umbrella trees have aggressive and shallow root systems that spread extensively as the tree matures.
“These roots crack and lift pavements, kerbs, drainage channels, and road surfaces. This damage reduces road durability, increases maintenance costs, and creates safety hazards for motorists, cyclists, and pedestrians,” she said.
She noted that the Council in the past year passed a by-law to encourage tree planting at household level as part of efforts to green Lusaka and improve the urban environment.
Ms. Mwamba, however said umbrella trees must not be planted on household boundaries near road infrastructure, road reserves, drainage lines, or underground services.
She urged residents to observe the recommended planting distance of at least 3 meters from any road infrastructure and to choose tree species with non-invasive root systems.
“LCC’s Parks and Recreation Unit under the Department of Engineering and Infrastructure Development is available to advise on suitable indigenous tree species that provide shade without damaging public assets,” Ms. Mwamba added.
“Community cooperation in responsible tree planting is essential to preserving public assets and extending the lifespan of Lusaka’s road network.”
