If your greenthumb can get a little forgetful, make sure you get the Bloem 18 in. Lucca Resin Window Box on your side. The planter comes with an attached basin that can be filled for the plant to feed from once the root system is established. To start the plant, use conventional top watering techniques, and then switch to bottom watering by filling the basin as needed for the roots to wick the water up. The fill spot is more subtle than traditional self-watering planters, giving the flower pot a more acceptable appearance. Choose from an array of quantities and colors to best suit your garden.
