Do Covered Planters Allow for Water Drainage?

How Water Drainage Works in Covered Planters

Outdoor resin planters should always have drainage holes to allow excess water to escape, preventing the roots from becoming waterlogged. When you add a decorative layer—such as pebbles or a resin-bound surface—it’s essential that your chosen covering does not block these holes. Permeable coverings, which allow water to pass through easily, are ideal for this purpose.

Choosing Permeable Coverings and Kits

If you aim to add an attractive layer to your planter while ensuring good drainage, select materials and binders designed to remain permeable. For example, the Flowstone permeable kit allows water to run freely through the decorative layer, avoiding unsightly puddles and helping roots breathe. Avoid fully sealing your planter’s base with non-permeable resins, or ensure you keep the drainage holes completely open.

Practical Tips for Covering Without Compromising Drainage

• Always check that drainage holes remain clear before and after adding your decorative layer.
• For resin and stone mixes, use binders specifically designed to stay permeable, such as those found in Polirock or Flowstone systems.
• If using a creative topping, do a simple drainage test by watering to make sure excess flows out easily.
