Featuring a water-reservoir that creates a self watering effect and a sub-irrigation water system which encourages root growth, this planter is a great choice for anyone who loves gardening. How does the Sub-Irrigation Water Reservoir work? These patio planters include a trough design creating a sub-irrigation water reservoir at the bottom of the planter. Capillary action allows water in the reservoir to soak upward keeping the soil and plant roots moist. To avoid oversaturation an overflow hole is drilled through the outside wall allowing excess water to drain out from the planter. Regular watering is required for the first few weeks giving the root system time to develop. Once the roots have grown down to the troughs the plants will be able to pull moisture from the reservoir creating a self-watering effect.
