Setting up the Bloomers Railing Planter takes minutes with these steps:

• Measure your rail width to confirm 1.25-3.875 inches fit.
• Slide the planter over the rail, using stabilizers at the bottom for grip; tap gently with a rubber mallet if needed.
• For extra security on windy decks, add zip ties, bungee cords, or screws through pre-marked spots.
• Line with pebbles for better drainage before adding soil.

Space multiple planters evenly along rails for a full cascade of color. Avoid drilling directly without caution to prevent rail damage.

Maximize success with plants suited to rail planters:

• Herbs: Basil, oregano, thyme, or mint thrive in the sunny, accessible spots.
• Flowers: Petunias, marigolds, or trailing ivy add vibrant porch appeal.
• Veggies: Lettuce, radishes, or baby carrots in the divided sections.

Use well-draining potting mix with perlite; aim for 20-25 dry quarts per 24-inch planter. Water regularly but let drain fully to prevent rot. Fertilize lightly every 4-6 weeks for steady growth.

Keep your rail planter thriving year-round:

• Empty soil in fall for winter storage or leave in mild climates since it's weatherproof.
• Clean with mild soap and water; avoid harsh chemicals on the BPA-free resin.
• Check stabilizers seasonally and tighten as needed.
