Hi. I'm new to the forum and this is my first post and I could use some helpful advice.
About 15 years ago I purchased a rooted cutting of a very large crested cactus that I was told was Pachycereus pringlei, though I do not know the actual species. Due to it's large size, it did not move with me and stayed at my parents house where I only see it every couple months. Long story short, after the recent heavy rains in Southern California, it became water logged and nobody noticed until it rotted from the inside and died. It had a single offset that crashed to the ground but appears mostly healthy.
The pup was about 22 inches long and had some mushy black rot around where it detached from the mother plant. I cut about 3 inches off the bottom until it appeared that no discoloration remained, and using what I had, cleaned it with alcohol and dusted it with strong Hormex rooting powder. I set it aside to callus but less than 24 hours later the wound has since turned brown in spots but appears firm.
Any advice for success is appreciated. This is my prized cactus and I want to do anything I can to save it. Does it look healthy? Should I address it differently or simply leave it alone to callus?
Also, can anyone identify the variety?
I am attaching a couple photos for reference.
Thanks,
Neil
