A planting system according to the present disclosure includes a pot configured to contain a planting medium, and an irrigation ring configured to be inserted within the pot and to irrigate the planting medium. The irrigation ring is an annular body including a first planar wall defining a first set of outlet openings, a second planar wall intersecting the first planar wall at a vertex and defining a second set of outlet openings, a third set of outlet openings formed along the vertex. The size, positions, and geometry of the outlet openings are selected so that water ejected from the ring saturates the planting medium substantially evenly throughout an annular wet zone in the top surface of the planting medium, while leaving dry zones in the center and the outer perimeter of the pot.
