Being one of the largest stores in the Maidenhead group, there is plenty to see at Birchen Grove Garden Centre. To start, there is an eighteen thousand litre Koi display pond with a viewing window, enabling you to watch the huge Koi gliding around under the surface. You can feed them too, with bags of Koi food on sale in store. Next is a two and three quarter metre long marine display tank and three, three metre tropical display tanks and two, two metre tropical display tanks to provide you with an amazing spectacle when visiting and to give you lots of inspiration. The store specializes in all areas of tropical, marine fish and invertebrates, and has an excellent range of fancy Goldfish, pond fish and Koi as well. Set within the Welsh Harp Environmental Area, this store must be one of London's best kept secrets.
