The Mystery of Watering Basins
Many restoration plans recommend the installation of watering basins. The specifications will read something like: "Restoration contractor shall install a watering basin consisting of a berm at least 3" to 4" tall with a minimum 3 ft. diameter around the plant." This makes no sense, unless you water the plants with a watering can or hose, but no one does this.
A watering basin is at best useless, and at worst creates a zone of overly saturated soil around the plant. Try to gently ignore the requirement for watering basins.
