Our stand-out pick

Rowlinson Marberry Square Planter

The Rowlinson Marberry Square arrives pre-assembled with a liner, so there’s no building to do before adding compost and plants. It holds 62 litres and has a 10-year anti-rot warranty.

The details

Five wooden planters at a glance

01 · Best lightweight cube

Rowlinson Square Planter

A neat 50 cm cube for patios where you want a simple square planter.

At £69.99, the Rowlinson Square Planter is the lowest-priced option here. It is a 50 cm cube with planed tongue-and-groove cladding and pyramid-topped corner posts. It holds 62 litres and weighs 10 kg, half the weight of the pre-assembled Marberry with the same capacity. It comes as a self-assembly kit, and the 10-year anti-rot warranty is included.

02 · Best ready assembled

Rowlinson Marberry Square Planter

A pre-assembled square planter with a liner included and a 10-year anti-rot warranty.

The Rowlinson Marberry Square Planter costs £95 and is built around convenience. It arrives already put together, and the liner is included, so the main jobs left are choosing a spot and adding compost and plants. It is 50 cm wide and deep but only 39 cm tall, so it sits lower than the cube-shaped Square Planter while holding the same 62 litres. Rounded corners give it a softer shape, and the wood is planed and pressure treated. At 20 kg, it is worth deciding where it goes before you fill it.

Price snapshot: £95.00 at One Garden, recorded 2026-11-02. Check the retailer page for the current price.

03 · Best for climbing plants

Rowlinson Square Planter and Lattice

Uses height rather than width, with a rear diamond trellis for climbing plants.

The Rowlinson Square Planter and Lattice costs £85 and stands 140 cm tall. A diamond trellis at the back gives climbing plants a place to grow, which suits a narrow spot where floor space is limited. The planter base is 40 × 40 cm and holds approximately 34 litres, the smallest capacity in this group. It comes as a self-assembly kit and weighs 10 kg, with a 10-year anti-rot warranty.

04 · Best large, ready-assembled planter

Zest Holywell Large Planter

A roomy square planter that arrives assembled, with far more capacity than the smaller Rowlinson models.

The Zest Holywell Large Planter costs £99.99 and holds 148 litres, more than twice the capacity of the 62-litre Rowlinson planters. It measures 60 × 60 × 65 cm, giving it room for larger plants or mixed planting. The boards are 12 mm tongue-and-groove with 45 mm framing, and the wood is pressure treated. It arrives pre-assembled and weighs 20 kg.

05 · Best for a raised bed

Zest Deep Root Planter 1.8m

The longest and deepest planter here, aimed at growing in volume rather than in pots.

At £169.99, the Zest Deep Root Planter 1.8m is the priciest option and works more like a raised bed than a patio pot. It measures 180 × 70 × 80 cm, offers a 38 cm growing depth and holds up to 500 litres. That is a lot of room for vegetables or a long run of planting. It needs self-assembly, and a liner is not included. At 41.5 kg before any compost goes in, it needs a settled spot. The warranty covers parts for 12 months.
