Why algae and lichen is a problem in Harpenden
On Harpenden properties, algae and lichen green film on paths, patios, render and signage that stains surfaces and makes them slippery through the winter. Around the common and the high street, Harpenden's mix of gardens, riverbanks, railway corridors and development plots gives invasive and persistent weeds plenty of disturbed ground to colonise, and infestations regularly cross property boundaries across Hertfordshire.
