Dahlia Pro-Tip: Martha Leaves Her Dahlia Tubers in the Ground Over Winter - April 2026
I don't know why I found this pretty shocking: Martha Stewart keeps her dahlia tubers in the ground all year long. Through the cold, harsh winter. How? She tarps them. That is genius. I shouldn't be surprised that Martha innovates in the garden. I can't embed her Instagram post, but you can see it all here . I've pasted a screenshot below showing how she tarps her dahlia beds and surrounds the perimeter with bales of hay. In her post, she talks about how she has found a way to eliminate the worst part of growing dahlias: yanking them out of the ground and storing them for the Winter. She points out that their enemy isn't just cold, but wetness. And, getting soggy will rot the tubers. After cutting down the stalks, she applies a fresh layer of compost. Then, yanks a tarp over the top and weighs it down. Remember what Martha said: If you want to be happy for a year, get marrie...
