The Keter Signature 21.6-inch square planter is a weather-resistant, wood-look self-watering pot that keeps plants healthy with an integrated reservoir and easy maintenance.

Combining classic wood aesthetics with modern resin durability, this Signature planter delivers the look of natural wood without the upkeep. At 18" wide and 21.6" tall, it offers a 20-gallon soil capacity suitable for medium to large flowers, shrubs, or mixed container gardens. The built-in water reservoir and readable level indicator simplify watering routines, while removable drainage options let you adapt it to indoor or outdoor use.

How does the self-watering system work?

The planter contains a dedicated water reservoir beneath the soil zone that supplies moisture to roots gradually, helping avoid overwatering or root rot. A clear water-level indicator shows when to refill and a drainage cup collects excess to signal when draining is needed.

• Full watering reservoir holds reserve moisture for dryer periods
• Visible water-level indicator for quick checks
• Drainage cup prevents sitting water and signals when to empty
• Optional drainage holes allow conversion to standard pots

Is this planter durable enough for year-round outdoor use?

Yes — the Keter Signature planter is molded from durable resin designed to resist sun, rain and cold without peeling, denting or rusting. The faux-wood texture retains the aesthetic of timber while standing up to outdoor exposure with minimal upkeep.

• Maintenance-free wood-look finish resists cracking and fading

• Sturdy build supports medium to large container plantings
• UV-stable materials maintain color over time
