I've tried to root saguaro cuttings and was unsuccessful. I didn't use rooting hormone. (I had permits to move or destroy the saguaro, each of which had to be tagged and recorded).
Perhaps it's "possible" with some technical or hormonal manipulation but doubt they would grow to full size and somewhat doubt it's possible at all. Otherwise commercial growers would do it (large saguaro for landscaping can be very expensive).
Other cactus (particularly the Opuntia, prickly pears and cholla) will propagate very easily from cuttings and do so in nature.
- zasdffaa 4y agoYeah, opuntia pads do root easily. I also won't have them in the house any more. Guess why (shudders with memories of pain) But other columnar cacti do root easily, eg. trichocereus (though it's is a mountainside cactus not desert) and I've rooted a few others of similar shape over the years, so I mistakenly assumed saguaro would as well.
- mythrwy 4y agoYep, San Pedro in particularly root really well from cuttings. (I won't ask "why" you were rooting trichocerus lol). But Saguaro are quite different. They have an internal woody skeleton. I think they are the only member of their genus. At any rate I failed completely to root them and all cuttings died. I've also seen them fallen over but not dead in the wild many times and they didn't root at the point they touched the soil. It's a completely understandable assumption that they would root from cuttings though as many other cactus do.
