It is a lovely thought, and a tree may grow from the soil provided, but after the 1,800-degree cremation process, the remaining bones are reduced to inorganic, basic carbon. With everything organic (including DNA) burned away, your sterile ashes are way past being useful to plants or trees. There are nutrients, but their combination is all wrong for plants, and don’t contribute to ecological cycles. Bios Urn charges $145 for one of their urns. The symbolism is beautiful. But symbolism does not make you part of the tree.
