Topping soil with decorative pebbles, stones, or even colored glass beads provides a polished, professional finish to home plant arrangements. These accents help retain soil moisture, prevent mess, and discourage pests, but their main role is aesthetic. The contrast of smooth pebbles against lush green leaves introduces a tactile quality, while metallic stones or radiant crystals add a touch of glamour. By matching the color and texture of your top dressing materials to your broader décor, you reinforce the cohesiveness and creativity of your indoor garden.
