You should pull up and remove weeds by hand as and when they appear. If it is a regular problem, you might need to reseal the paving. In extreme cases, the sub layer itself may need to be re-laid. You can use weed killer, however some paving can be discoloured by stronger weed killers.
New Quay
New Quay is a seaside community (as well as selecting ward) in Ceredigion, Wales with a resident population of around 1,200 people, lowering to 1,082 at the 2011 census. Situated on Cardigan Bay with a harbour and huge sandy coastlines, it pushes the Ceredigion Coast Path, as well as continues to be a prominent seaside resort and typical angling community. Along with stores, dining establishments as well as pubs, New Quay has a big primary school, a doctors' surgical treatment, a small branch of the county library service as well as a fire station. New Quay Lifeboat Station, run by the RNLI, houses two lifeboats: a Mersey class called Frank and Lena Clifford of Stourbridge in commitment to its major benefactors and an inshore inflatable D class. In 2014 the terminal commemorated 150 years of service, throughout which period it made 940 callouts. Public transport is given by regular bus services to Aberaeron, Cardigan as well as Aberystwyth. The town has never ever had a train service, as plans to open paths to Cardigan or Newcastle Emlyn were deserted in the 1860s, and that from the Aberaeron to Lampeter branch line (the Lampeter, Aberayron as well as New Quay Light Railway) was never ever finished due to the First World War. A couple of miles outside New Quay is a honey farm. There is a public park on top of New Quay beside a tennis court.
