"We go way over-the-top," Shelton confessed to a news publication about his hidden hobby. "It's embarrassing how much we spend on seeds."
"Besides music, gardening has been our biggest bonding activity," the country sensation continued to reveal of him and the "Hollaback Girl" singer's various zinnias and sunflower-filled gardens. Meanwhile, Shelton admitted that the couple has ways to go when it comes to successfully growing Icelandic lilies.
While his passion for gardening has always taken a back seat to his music career and 12-year run as a judge for NBC's famed singing competition series, Shelton is ready to officially retire to a recliner instead of his large red throne on The Voice.
"Gwen and I have done so much traveling and touring and work the first half of our lives that now we're like, 'Hey, I'm good to put my sweatpants on at 6 p.m. and watch Ozark eight times,'" Shelton admitted of his exciting new chapter, as the show's live season finale is set to air on Tuesday, December 13. "That's our life now, and we love it."

Although the "Nobody But You" singer feels ready to devote his time to joy-filled hobbies and taking care of his three stepsons, Kingston, 16, Zuma, 14 and Apollo, 8, Shelton admitted that leaving his famed role on the competition show is bittersweet.
"The holdup over the years has been that it's a hard thing for me to let go of. I've been here literally since the first minute," the "God Gave Me You" crooner — who has been a judge on the show since the very first season in 2011 — explained. "When I started on The Voice, that was 10 years into my career as a country artist. I never really made it to the A-level of country artists until I became a coach."
"The show did a hell of a lot more for me than I brought to the table at the time. I've far exceeded anything I thought I could ever accomplish in the entertainment world," Shelton gushed.
