Mayne Cape Cod 20x20 Square Planter — 20" White Polyethylene Double-Wall with Reservoir

The Mayne Cape Cod 20" square planter is a durable, double-wall polyethylene pot with a built-in water reservoir, designed for year-round outdoor use and long-lasting color retention.

This 20 x 20-inch white planter from Mayne delivers a low-maintenance container solution for patios, terraces, entryways and commercial landscapes. Made from 100% high-grade polyethylene resin with UV inhibitors, the Cape Cod planter balances lightweight handling with impact resistance. Its double-wall construction improves insulation for roots, and the integrated reservoir reduces how often you need to water.

How does the Cape Cod planter hold up through all four seasons?

The planter is built to tolerate sun, rain, wind and winter freeze-thaw cycles with minimal prep. UV inhibitors in the resin slow fading and the high-impact material resists cracking and chemical damage.

• 100% high-grade polyethylene resists dents and shocks
• UV-stabilized material reduces sun-related color loss
• Weather-resistant construction for year-round outdoor placement

What makes the double-wall design beneficial for plants and stability?

The double-wall shell creates an insulating air gap that buffers temperature swings and protects roots from direct exposure. It also provides a robust structure that can be weighted for windy locations.

• Insulating cavity reduces soil temperature fluctuation
• Can be filled with sand or gravel to increase anchoring
• Sturdy walls keep shape under load and over time

How does the built-in water reservoir improve plant care?

A concealed reservoir stores water below the soil zone so plants can access moisture steadily, which lightens your watering schedule and helps prevent overwatering at the surface. It’s especially helpful for busy homeowners or public plantings.

• Approximately 8.75 gallons (33 liters) reservoir capacity
• Consistent moisture availability reduces frequent surface watering
• Promotes healthier root development by encouraging wicking from below
