Our saucers resist harsh weather conditions, making them suitable for outdoor use. Grooves at the bottom of the tray direct standing water away from your plants to prevent root rot.CLEAR AND TRANSPARENT: Each round plastic saucer is transparent and therefore practical for seeing the quantity of water remaining at the bottom of each. Their neutrality does not distort the beauty of the plant. Each transparent flower pot tray is placed discreetly under your pots and harmonizes perfectly with plants, flowers and pots of all colors. Add stones and rocks to the bottom to give your plants a unique touch.SURFACE PROTECTION: Each plant saucer sits under your pots and allows excess water to drain and prevents overwatering. They protect your surfaces from water and soil and from damage and stains. Use these saucers for ceramic, plastic and clay flower pots, indoors and outdoors. Our containers are not just for plants. Use them as dog water bowls, pet feeders and to store small candies and snacks.
