Abstract
A device for watering and feeding living plants including a cylindrical tube, closed at the bottom and the top having a funnel-shaped orifice to receive and hold an inverted reservoir (for example, a two or three liter plastic bottle). The tube is buried vertically in earth or plant soil to expose only the orifice, which may be capped when not in use allowing camouflage of the device at the soil surface. Two holes in the sidewall of the tube allow water and water soluble plant nutrients to pass therethrough slowly.
