I have 8 San Pedros in the ground; two of them were planted out recently (November?) and their root systems weren't that extensive at the time of planting. The other day I noticed damage on one of the two recently planted ones. The other 7 San Pedros are ok (including the other recently planted one), as are my single specimens of T. peruvianus and T. bridgesii. We've had some frosts recently and I'm wondering if this could be frost damage? Why would it only have happened to one of the cacti and not the others? It's basically shriveled at the top, and a couple of the topmost inches have turned light blue, in contrast to the bluish green further down. This cactus has the weakest root system of all my cacti or isn't planted deep enough. It's kind of wobbly and moves when I push it with my finger.

It looks a bit more like sunburn than frost damage. Though, it could be a combination. + ---- + ---- + ---- + ---- + ---- + ---- + ---- + ---- DMT Nexus Research ---- + ---- + ---- + ---- + ---- + ---- + ---- + ---- +

Here's some proper frost damage: downwardsfromzero attached the following image(s): IMG_9932.JPG (4,150kb) downloaded 129 time(s). “There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work." ― Jacques Bergier, quoting Fulcanelli

Damn. That sucks. It must have been a bad freeze to cause that kind of damage. Usually you just see damage to the tips. Hopefully its not all destroyed. IT WAS ALL A DREAM

-6°C was too cold! I'm not too worried as I have other plants indoors; this trough was just too big. I'll just have to tidy up that mess... somehow  With some luck, there'll be new shoots come the summer. (This was an experiment in cactus cold tolerance. A little wicked imp made me do it.) “There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'.

Jagube I haven't seen that particular type damage before. Downwardsfromzero I hope you made lots of lemonade with those lemons.  On a related note, here's a lesson I learned last Winter: Give them a little water every now and then. I had mine overwinter in a greenhouse tent and didn't give them water all Winter, and they were only in the tent from the middle of December to the end of February. This is what happened to some of my Lumberjacks: Wolfnippletip attached the following image(s): 3-25-18-01.jpg (131kb) downloaded 115 time(s).My flesh moves, like liquid. My mind is cut loose.

I let my cacti get frozen as well this year... as luck would have it I have a few survivors and even one about to bloom! Wakinyan attached the following image(s): flowertrich.png (622kb) downloaded 86 time(s).When I graft you graft we graft

In the interests of science, I allowed some frost-damaged stems from the above selection to stay in place in order to see how things would develop.

Close call with some seedlings. They were brought inside before the temp became lower than 0C. 0_o attached the following image(s): IMG_20190329_021206.jpg (665kb) downloaded 61 time(s).

Please look away now if you're easily disturbed! I'll update here to say that eight cuttings from the "big freeze and rot" have happily survived and have now become 21 growing stems.
