Lazygardens I must be much lazier than you! I didn't find the occasion you did, but here's what I did find: Greg Simpson, in 2006, on another forum site~ "You can plant saguaro arms (and cuttings), but the chance of them rooting is at best 50/50. Generally speaking, large thick cacti will root, but it takes a lot of time and patience. Just make sure you let the cut heal for at least 3 weeks before planting or it will rot. It must be oriented north/south just like it was on the main plant and mix about 50% sand into the soil when planting...and do not water! Water it after it has been in the ground for a month or so, but only if there hasn't been any rain. If it roots, you will see new growth next season. Good luck! Sincerely, Greg" From "The Cactus Doctor"~ "If you have a saguaro cutting, hereÂs what to do- 1. Whenever possible, make the cut at a joint. 2. Let the cutting air-dry for 1-2 months, making sure the end is hard & calloused before planting. 3. Leaving about 3 inches left at the top, fill a 15 gallon container with silt (river bottom sand). 4. Center the cutting in the pot, and fill the rest with silt, packing it around the cactus. 5. If the cutting is not acclimated to the sun, cover it for the summer. 6. Leave it potted for 1-2 years, so the roots can grow. Now youÂre ready to put it in the ground!" From Cactus Art Nursery~ "Propagation: From stem cuttings (if available) in spring (let them dry till the ends callous well. Then replant them in fresh cactus soil that is ever so slightly moist, and keep it that way till they root)" It's a low yield effort: searching the web gives about one reference per two pages of results! Hope what I found helps. Kevin : ])

Dont worry about it, it will go away. Ive had it, my plant is fine now . think its stress or smth...

Susan this is off topic of that particular plant ID but wanted to share some articles with you regarding the plant’s smell. oils of plants may be more effective than Antibiotics: http://outbreaknewstoday.com/johns-hopkins-researchers-plant-compounds-may-better-current-antibiotics-treating-persistent-lyme-bacteria-16025/ And https://www.nationalgeographic.com/magazine/2019/01/ancient-chines-remedies-changing-modern-medicine/ Thank you for pointing out your instincts may be onto something. Also take a look into concurrent mold-related inflammations because that‘s a common thing that people can normally deal with by itself, but not when also dealing wiith Lyme. I wish you an effective recovery.

Thanks for your responses. The honeydew melon one rotted in the two weeks I've had it sitting out to callous over - it has turned dark gray/black. It's a separate piece as are the other two. I'm disappointed to hear they are difficult to root but at least now I'll know it wasn't totally me. I gave the largest one to my boyfriend and he planted it about six inches into the ground. I was afraid that might be too deep and it might rot. I'll go ahead and plant mine and say a prayer :)
