> source: I moved and planted saguaro professionally for like 5 years OK, I'm pretty well destroyed here! Great comeback. Regarding your germination notes, I would suggest contacting suitable cactus organisations. Here in the UK there's one (british cactus society) also a major cactus grower in Matlock Bath (http://www.abbeybrookcacti.com/ http://www.abbeybrookcacti.com/) and any suitable over there in the US. What you've got may be valuable info. re. germination, you might want to play with ethylene as it's a plant hormone associated with ripening and germination - crushed fruit might very well emit ethylene (https://en.wikipedia.org/wiki/Ethylene_as_a_plant_hormone https://en.wikipedia.org/wiki/Ethylene_as_a_plant_hormone). I wonder, how do baby saguaro respond to grafting onto vigorous rootstock? Is that a possible avenue?
