How Long Does a Wicker Coffin Take to Decompose?

A wicker coffin usually breaks down completely within two to five years once it's buried. That's a fraction of the time it takes a traditional hardwood or metal coffin to decompose, and it's exactly why so many families choosing a green burial pick wicker in the first place.

If you're comparing coffin types, or just curious about what happens after a woodland burial, here's a clear look at why wicker breaks down so quickly, what affects the timeline, and why a faster decomposition is actually a good thing.

Why Wicker Breaks Down So Much Faster

Wicker coffins are handwoven from natural plant materials like willow, seagrass, or rattan, with no metal fixings, no varnish, and no synthetic lining. There's nothing added that would slow nature down.

Compare that to a traditional coffin. Hardwood coffins are often sealed with varnish or lacquer, which acts like a raincoat, keeping moisture out and slowing decay for decades. Metal coffins go even further. Steel ones can stay largely intact for 50 to 80 years, and some bronze or copper coffins can last over a century.

Wicker has none of that protection, and that's the whole point. Every part of it, the base, the sides, the lid, is designed to let air and moisture in, so soil bacteria can get to work straight away.

What Affects the Timeline

While two to five years is the general rule, a few things can speed things up or slow them down a little:

• Soil type. Damp, acidic soil breaks materials down faster than dry, sandy ground.
• Burial depth. Natural burial grounds often use shallower graves than traditional cemeteries, which means more oxygen reaches the coffin and speeds up the process.
• Weather and climate. Warmer, wetter conditions encourage the bacteria and fungi responsible for decomposition. Cooler, drier ground slows them down.
• The specific material. Willow tends to break down a little faster than denser materials like bamboo or seagrass, though the difference is usually measured in months, not years.

None of these factors change the outcome, just how quickly it happens. Within a natural burial ground especially, conditions are usually close to ideal.

Wicker vs Wood vs Metal

If you're weighing up coffin materials for a green funeral , this is usually the deciding factor for families who want as little lasting impact on the land as possible.

Is Faster Decomposition a Good Thing?

For a green burial, yes, and it's worth understanding why. The whole idea behind a natural burial ground is letting the land return to something close to its wild state, with wildflowers, trees, and grass growing undisturbed. A coffin that lingers for decades works against that. One that returns to the earth within a few years works with it.

It's also worth knowing that a faster breakdown doesn't mean a flimsy coffin. Our own wicker coffins are weight-tested to 190kg and built on a solid base, so there's no trade-off between strength on the day and a natural end afterwards.

A Natural Ending

Choosing a wicker coffin means choosing a send-off that finishes the way it started, gently and naturally. If you'd like to see the range for yourself, you can browse our willow coffin collection , or take a look at our FAQ page for more answers like these.
