Crescent Garden planter saucers are designed for durability and ease of use and are 100 percent recyclable. Deep plastic plant saucers are ideal for plants that require a lot of watering. Leave them filled with excess water to continue watering through the root system even when you forget to top water containers. These heavy-duty plant saucers, designed to withstand heavy pots, will easily catch excess water while the transparent colorless material will subtly blend in with your planter.
