Add in your apples, pinecones, or ornaments in the holes between the cyclamen. Instead of adding potting soil to fill in the space, simply squash your plastic pots, flip them upside down and use them to add height before placing the apples.
Finally, a bit a of height and sparkle! Add silver branches for a holiday touch throughout the center of your container. If you don’t want to buy the branches, find some thin branches and use Rustoleum metallic paints in silver or gold.
