Looking after it

Let the patina form on its own over the first one to three months and keep it off a pale paving surface while it does, because rust run-off stains. Plug or unplug the drainage holes to suit what you are growing.

A trough planter in A606-4 weathering steel, 91.4 cm long.

Bolted together from flat panels with the nuts, bolts and instructions in the box. It measures 91.4 cm long, 30.5 cm wide and 40.6 cm tall, and the drainage holes are pluggable.

A rectangular trough that reads as a single block of rusted steel once the patina is up, and gives you 91.4 cm of planting length.

The listing gives the size as 91.4 cm long, 30.5 cm wide and 40.6 cm tall (36 by 12 by 16 inches).

It arrives flat and bolts together with the nuts, bolts and instructions supplied.

The steel is A606-4 weathering steel, which forms its rust patina over one to three months and then holds it.

Drainage holes come with plugs, so you decide whether it drains freely or holds water for thirstier plants.

Rectangular Planter Box

A trough planter does a job a round pot cannot: it lines a path, edges a patio or screens a balcony rail, and it holds enough soil for vegetables rather than a single ornamental.

Rectangular Planter Box

This one is A606-4 weathering steel. It arrives grey and turns through orange to a deep brown over the first one to three months outdoors. That patina is the finish, and it protects the steel beneath it.

Rectangular Planter Box

The panels bolt together with the hardware supplied. Allow a few minutes with a spanner, and check the bolts again after the first season.

Rectangular Planter Box

Drainage is up to you. The holes have plugs, so a trough of herbs on a balcony can be left to drain and a trough of thirstier plants can hold more water.

Rectangular Planter Box

One figure on the listing does not add up: it gives the weight as 78.2 kg and as 38 lb, and those are not the same number. If the weight matters for a balcony or a raised deck, ask us before you order and we will confirm it with the supplier.

Not sure yet? That is fine.

You can change your mind. This shop's own returns policy gives you 15 days from purchase to send it back in its original packaging with proof of purchase, and we refund the price you paid for the goods.

If it turns up faulty, damaged or not as described, that is on us. The Australian Consumer Law covers you, we pay the return postage, and you can have a repair, a replacement or your money back. Read the full detail on our refunds and returns page, or ask us anything before you order.
