The connected devices craze appears to be spreading to the yard, and Urbana-based startup PlantLink is trying to stake its claim. PlantLink, which makes a sensor that tells users when their plants need to be watered, is partnering with industry juggernaut Scotts Miracle-Gro on its mission to get millennials and younger generations into gardening. Scotts released the Gro app this week to coincide with Earth Day. The app can pair with PlantLink and other Connected Yard devices, like smart sprinklers. The partnership will provide a wider customer base for PlantLink and the other devices, and display them together at retailers. PlantLink's new products will be added to those displays in 2017. This could be PlantLink's second chance.
