But now britons have fallen in love with artificial grass.Evergreen UK,which sells the stuff,says it has seen a 120% rise in sales since 2015. Artificial grass is popular with families who have children or dogs and don’t want mud dragged through their houses. It has another charming factor,too - people now see gardens as “outside rooms”- pairing carpet of artificial grass with delicately decorated seating and hot containers.           

Not everyone is a fan. Artificial grass contains microplastics that ruins soil and risk flooding. A study finds earthworms gain 14% less body weight when operating under rubber, a form of artificial grass, which might not be a problem for its fans,as wormholes are regular disgusting things,but it disappoints green types. Ms Davison of the RHS(皇家园艺学会)says a group of wildlife-loving gardeners is booming,many having caught the bug during COVID-19 lockdowns. For example, a landscape designer says they like things less neat and try “to capture that wild element”.These eco-gardeners are influenced by rewilding project and are more likely to be environmentalists.
