Mayne 20in Self-Watering Square Planter, Black — UV-Stable Double-Wall Coastal Bead-Board

Designed to evoke a coastal aesthetic while standing up to sun and weather, this 20-inch square planter in black brings both curb appeal and practical performance to porches, patios, balconies, and entryways. Its double-wall polyethylene construction offers insulation and impact resistance, while the built-in reservoir and overflow drainage simplify watering routines so plants get consistent moisture without frequent attention.

How does the self-watering system simplify plant care?

The planter includes a hidden reservoir beneath the soil zone so roots can draw moisture as needed, reducing the risk of drying out between waterings. An overflow outlet prevents waterlogging and helps protect roots from rot when you fill the reservoir.

• Integrated water reservoir feeds roots from below for steady moisture
• Overflow drain prevents excess water accumulation and root suffocation
• Less frequent surface watering saves time and reduces maintenance

Will this planter resist sun, cold, and outdoor wear?

Yes — the UV fade-resistant polyethylene resists color loss and brittle cracking from extended sun exposure. The double-wall design provides insulation that buffers temperature swings, helping roots survive hotter summers and colder nights better than single-wall pots.

• UV-stable material preserves black finish and appearance
• Double-wall construction increases thermal protection for roots
• Durable polyethylene stands up to impacts and seasonal conditions

What size and style benefits does the 20-inch square form offer?

The 20" square footprint makes a bold statement while remaining versatile for single large specimen plants or mixed seasonal displays. The classic bead-board texture gives a refined coastal look that complements traditional and contemporary settings alike.

• 20-inch size fits doorways, wide steps, and patio corners
• Square shape suits grouped arrangements and tight spaces
• Bead-board aesthetic adds timeless, coastal-inspired charm

What warranty and origin information should buyers know?

Manufactured in the USA, this planter is backed by a 15-year limited residential warranty for long-term outdoor use. That coverage reflects confidence in materials and construction while offering homeowners peace of mind for seasonal planting projects.

• Proudly made in the USA with quality-controlled production
• 15-year limited residential warranty covers material failures
