In recent years, garden centres have evolved to become a leisure destination with play centres for children, restaurants and other activities designed to improve the shopping experience and increase the time spent at the centre. These changes have partly come about because the main competitors to the traditional garden centres, such as the DIY chains, have brought down prices. Competition has also increased from online garden centres such as Crocus and Greenfingers, although companies such as Capital Gardens, Dobbies, Riverside Garden Centre and The Garden Centre Group have now responded by developing and marketing their own online operations. Some open-air attractions (e.g., National Trust properties, the RHS Garden, Wisley, Westonbirt Arboretum) also run small garden centres as additional sources of revenue or to discourage the unofficial taking of plant cuttings.
