Hello,
Next week, a massive Giant Sequoia tree is being felled in my area, and I’d love to collect some cuttings to try propagating it. As a beginner, I’m wondering:

How thick can a cutting realistically be to have a chance of rooting?

I know that thinner cuttings tend to root more easily, but I’d like to try using thicker ones to get a bigger head start. Is it possible to root thick hardwood cuttings, or is that too difficult?

Any tips, advice, or success stories would be greatly appreciated. I’d love to preserve a piece of this beautiful tree.

I am not sure they will root, but why not take bigger as well as smaller pieces. I think a propagator at this time of year will be needed.
