90cm Pine Deep Square Wooden Sleeper Raised Bed Planter

The Caledonian Square Raised Bed delivers an exceptional 42cm planting depth and 270-litre soil capacity, engineered specifically for crops requiring substantial root run. By elevating the root zone, it enhances thermal soil retention in spring and delivers superior drainage during heavy autumn rainfall.

Built with heavy-gauge timber sleepers utilizing notched half-lap joints, the frame maintains its shape under maximum wet compost load. Pressure-treated against rot with a 15-year guarantee, it provides serious growers with a reliable, high-yield vegetable bed.

Key Highlights:

• Deep 42cm Root Zone: Optimal volume for parsnips, carrots, brassicas, and deep-feeding crops.
• 270L Compost Capacity: Massive nutrient reservoir reduces watering frequency during summer dry spells.
• Precision Machined Sleepers: Half-lap joints interlock tightly for quick assembly and lasting strength.
• 15-Year Anti-Rot Protection: Suitable for direct soil contact with zero annual timber treatment needed.
• Clean 90x90cm Footprint: Open base with no floor — sits on soil. Fits gardens, allotments, and patio perimeters.
