When it comes to country music, it seems like everything Blake Shelton touches turns to gold — but the singer isn’t quite as lucky when it comes to one of his other passions.

In a recent interview with CMT, the 48-year-old Voice star admitted he’s been having a hard time growing a particular crop on the sprawling Oklahoma ranch he shares with wife Gwen Stefani.

“I think fans would be surprised to know that I am a struggling flower gardener. Struggling,” he said.

“It’s something that Gwen and I do together, but you know, if I’m gonna plant flowers I wanna do like 10 acres of flowers so I can use my equipment, my tractors, really tear some crap up,” Shelton continued, adding, “So far, not so good.”

It could be that Stefani, 55, has a greener thumb than her husband.

In a 2024 interview with Nylon, Shelton praised the former No Doubt singer for her skills in the garden.

“Gwen has an incredible sense for planting things: how to grow them and, once it’s growing, how to cultivate it, and when to prune something,” he said. “I like to farm on a big scale, like corn or beans, acres at a time. She concentrates more on patches here and there and ends up farming things a little better than I do.”

“Gwen has her own tractor now, and we’re working toward her one day soon being able to fire it up and go out to do her own thing on it,” he added.
