At 36 inches wide and 3 gallons capacity, it suits small to medium displays of flowers, herbs, or trailing plants, making it great for beginners building curb appeal.

Key features shine in real-world use: the self-watering reservoir delivers steady moisture to roots, reducing wilting from missed waterings, while overflow drainage avoids soggy soil during heavy rains. Mount it securely with included brackets, fill via the port, and watch petunias or geraniums thrive with minimal effort.

Start with well-draining potting mix suited for containers to complement the self-watering system. Fill the reservoir to the line, then add soil and plants.

• Choose sun-loving flowers like petunias, impatiens, or million bells for south-facing spots.
• Mix heights: tall center plants, medium fillers, and trailing edges for lush fullness.

Water topsoil weekly to activate the reservoir, adjusting for hot weather.

Secure brackets to sturdy surfaces like window frames or railings using provided hardware. Level the box for even watering, and plug the fill port when not in use.

• Measure twice: 11-inch depth needs 12 inches of clearance.
• Two-person lift recommended due to 13.5-pound weight when full.
• Clean quarterly with mild soap and hose; store indoors in extreme winters.

Check drainage holes yearly to prevent clogs from soil debris.

Transition plants easily: summer annuals to fall mums, then winter greens or empty for storage.

• Spring: Refresh soil and start seeds indoors before transplanting.
