Unique Self Watering Baskets and Planters that really work. Simply water the Basket/Planter from above in the usual way as in the base there is a reservoir that will collect all excess water. The basket will then be kept moist by combination of a wick and capillary action. Should only need to be watered once a week depending on conditions. Drainage holes around the top of the resevoir prevent over-watering and allow excess rainwater to drain through.
