Once the reservoir of your planter is filled to capacity, water will start seeping out of the overflow drain hole. Always make sure there is a clean passage way out of the drainage hole to ensure water can escape.
The Overflow drain hole is manufactured/pre-drilled in all of our window boxes and Patio Planters.
Our Tall Planters require you to drill your own drainage hole. The hole is not pre-drilled in our tall planters so the you can best decide placement based on how you choose to use your planter. Instructions for placement of these drain holes is included below.
