Wine Bottle Planters, beautiful. Cut off the bottom of the bottles. We wouldn’t be able to use potting soil as our planting medium. From the look of the pictures, it seems moss was used—perhaps peat? Wire bound or small rope tied just below the bottle’s threads is all we’d need to hang. You don’t need to wire in the plant. You have to give it at least 2 weeks growing, with the bottle upside down & the plant growing upward in the natural position. When the roots take, it should stay put after hanging. If you are unsure, a light wire cage & moss can be used but don’t inhibit the root growth.
