How to use and plant your Bios Urn in nature

We are dedicating this blog post entirely to planting instructions for the Bios Urn. If you have any other questions, please feel free to add a comment down below, and we will help answer them.

We try to make the Bios Urn as user-friendly as possible. The Bios Urn itself is divided into two capsules: a lower capsule, and an upper capsule. The upper capsule comes sealed and contains a soil expansion disc, growth medium, and seeds of your choosing.

Instructions for using the Bios Urn

1. Fill the lower capsule of the Bios Urn with ash (any amount, regardless of how little can be used.) The Bios Urn can be filled by a crematorium, or by the individual user. Thanks to its double capsule design, the Bios Urn locks into place, so that a crematorium can give the ash back to you ready to plant. Once the ashes have been transferred to the lower capsule, close the lower capsule with the top capsule by sealing it into place (place the top capsule on top, and then twist it slightly to the side).

2. Choose the location or planting spot for your Bios Urn. If you need assistance with this, contact us here, or leave a comment below.

3. Plant your Bios Urn! Dig a hole large enough to accommodate the Bios Urn. Generally around 15-16 inches (36-37cm) is a good depth, with a width of 10-12 inches. Plant the Bios Urn inside, leaving the soil surface a couple of fingers above the top of the urn. TIP: water the entire hole before you plant the Bios Urn into it, as this will help begin the process of biodegradation. If you plan on using a Bios Incube, you will receive instructions for use, as well as the amount of extra soil needed.

4. Remove the seal from the top capsule, and unpack the components (soil expansion disc, growth medium, and seeds.) Place the growth medium inside the top capsule. We recommend adding additional soil from the site you are planting the Bios Urn, on top of the growth medium. Place the seeds on the very top!

5. Cover the Bios Urn with soil from the surrounding area, and thoroughly water the spot you have planted it. There should be around 1/4 inch to ½ inc of soil on top of the seeds (make sure you don´t place too much on top!) None of the Bios Urn should be exposed, it should all be covered by soil.

Simply plant your urn where you want your tree to grow and take care of it. Always plant all of the urn, which is 100% biodegradable and won’t damage the soil. You can plant your Bios Urn using a seed or a young sprout if you prefer. We generally recommend planting during the appropriate season according to your tree. If you have questions about when to plant your Bios Urn according to your location, message us, and we will assist you with this process.

Remember that Bios Urn can be saved for as much time as you want because it doesn’t have an expiration date. If you don’t plan on using your Bios Urn anytime soon, we recommend getting a Bios Urn without a seed and then adding the seeds when the time for planting comes.

    • Hi Colette,

      That really depends on the seed used. Some last for a year, while others can remain dormant for up to 6. We recommend acquiring one without a seed, and contacting us if you need seeds in the future, or acquiring some locally. We can accommodate both requests 🙂

    • Hi Hans! The Bios Urn can hold 220 cubic inches of ash. It cannot hold the full amount for two people, although you could divide in into two and split the portions in half. You could also use two Bios Urns if you would like.

  1. Una ves que estás listo para plantar cuánta agua necesita para que la semilla prenda ?
    Es un maple el árbol que compramos y que tan seguido es necesario regarla ?

    • Hola Mayra! Cada árbol requiere diferentes cantidades de agua. Los árboles recién plantados requieren riego regular durante los períodos en que hay poca precipitación. Algunos Arboristas recomiendan regar árboles jóvenes dos veces por semana.

  2. Where does the expansion disc go? Top or bottom? The instructions do not seem to say.

    • Hi Ward! Thanks for letting us know. The expansion disc goes at the bottom of the top capsule, followed by vermiculite on top and additional soil 🙂

    • Hi Petra, there are rarely issues of non-growth. The most important thing to ensure growth is planting an appropriate tree species (see here for zones: We also recommend planting during the correct season, which generally falls between spring and late fall! If you need specific help based on your tree type, we can send you additional info via email or by phone.
