Chief operating officer George Williams, son of Burncoose Nurseries/Caerhays Castle owner Charles Williams, said PlantSnapp started two years ago as a "simple plant-identification app" for 25- to 35-year-old non-gardeners.
The app now includes a monthly checklist of garden tasks and has launched on Android as well as Apple devices. Williams said there were 1,000 per cent more downloads this year than last year.
The app is "not for average gardening folk", he added. "They are people who aren’t gardeners but who quite like having an outdoor space." The community side is expanding but the app differs from others such as Garden Tags because it is not primarily a chat-based application.
"There are many people in their 20s and 30s and older who like having a garden to relax in but wouldn’t call themselves gardeners," said Williams. "Gardening sometimes suffers from a nerdy image so we’re trying to make it simple and easy for people to make the most of their outdoor spaces, without having to become gardening geeks."
Some 50 experts including Peter Mills and Rob Stacewicz identify and give advice on plants photographed and sent in by users. There are three free credits plus one a month afterwards. Premium membership (£36 a year) gives unlimited access plus My Garden and Care Calendar features.
