Any success rooting Redwood Burls?

[Notsureaboutplantnames]

Has anyone roots portions of Sequoia sempervirens burls?
I have access to several large burls with active shots emerging and have permission to remove small pieces.

I have no experience with this but Dan Robinson has a Coast Redwood bonsai grown from a burl.

They used to sell live burls in bags in tourist shops on the Cali coast. They said the burls would sprout in a pan of water. Never tried it but it mostly works from what I’ve heard

Thanks.... I have had one in the past in water but never saw roots. I guess I will not give up early this time.

I don't have experience rooting burls specifically, but it makes sense that it would work; burls are typically packed with hyperactive cells. I would treat it like any other cutting, it will probably take a few months for roots to start coming out. For redwoods, maybe up to a year. Someone here mentioned they grew one for 5 years in water: https://www.bonsainut.com/threads/safe-to-repot-after-redwood-burl-puts-out-roots.9508/page-2

Interesting. There is an old fruit tree (flowering plum) next door that has a cut off old branch about 3-4" in diameter and sticks out about 3". It's pretty rough looking but it has 3-4 starts of the mother tree that are about 6-8" long and doing well. If I cut that off flush with the tree and put it in water or something and get it to grow. Sorry for the bad pictures. Help appreciated

I came across a website I read several years ago about how redwood branches naturally layer when buried under some redwood duff or other OM. I had failed to look up the presented references until a few days ago. The references are for a scientific paper and a "gardener" publication in Arnoldia both authored by Peter Del Tredici. I can post up the pdf files if you would prefer.

Very interesting read for sure. I have been familiar with burls for years, and lignotubers on many Australian and California natives but never on Redwoods.

I ride my bike past this tree with these really odd "roots" but I never stopped nor investigated what they are until a few days ago.

These lignotubers are numerous and varying in size from a hint of growth to over 4' long. Hard to see in pictures, I should have taken one showing the base of the tree but these are on a serious road cut which is why they are doing what the author said they do.
