Flower Well is a sturdy plastic reservoir for hanging baskets and planters that captures water and food that would otherwise drain away. So your hanging baskets can go longer before watering and dripping is much reduced. Holding a full quart, Flower Well concentrates the liquid in a central well from which plant roots and capillary action can draw up the nourishment. Made from recycled material, Flower Wells can be re-used over and over again. Top has over 100 drainage holes, central well is 2" across. 8-3/4" across overall x 1-3/4" deep. Fits baskets and planters 12" diameter and above.
