Why Choose This Planter?

• Spacious Growing Area: The generous depth allows you to grow a wide range of plants—from colourful annuals and perennials to fresh herbs and salad greens.
• Trellis Back Panel: Provide vital support for vines or climbing flowers, encouraging upward growth and maximising limited space.
• Long-Lasting Construction: The wood-plastic composite boards are weather-resistant, so they won’t crack or fade in sun or rain. The powder-coated aluminium frame adds extra durability for year-round use.
• Healthy Roots: A built-in drainage hole keeps soil well-aerated and prevents root rot by allowing excess water to escape.

Planting & Care Guide

• Best For: Climbing annuals (sweet peas, nasturtiums), perennial vines (clematis), trailing flowers (petunias), herbs (mint, parsley), compact vegetables (lettuce, radish).
• Light Requirements: Place in full sun to partial shade depending on plant choice. Most climbers thrive with at least 6 hours of sunlight daily.
• Soil Type: Use a quality multi-purpose compost; amend with slow-release fertiliser for season-long growth.
• Irrigation: Water regularly to keep soil moist but not soggy. Ensure the drainage hole remains clear for healthy roots.
• Caring Tips: Train young vines onto the trellis using soft ties. Prune spent flowers to encourage new blooms throughout the season.

Design Inspiration & Placement Ideas

• Create a lush privacy screen on patios or balconies by grouping several planters together.
• Add vertical interest to courtyards or frame entryways with flowering climbers.
• Pair with companion plants like marigolds or nasturtiums to attract pollinators and enhance visual appeal.
