rooting issue

Lakeland, FL(Zone 10a)

Hi-

I am new to this forum and have 2 questions that I hope someone can answer

1. I recently got a large unrooted piece of Tephrocactus articulatus v. syringacanthus and am wondering how best to root it. I had a little problem with some rotting so sealed up the wound, after removing the rot, with a pruning sealer. Should I have the cutting just touching the media or should I bury a little of it? What is the best media to use? I don't want loose this, I love the paper spine cacti and this one is awesome.

2. Can someone tell me the name of this cactus in the pic? I friend had one long ago and I have never new the name and have not been beern able to locate one. I love the geometry of the spines and have always wanted one and would love to know the best place to find it.
Thanks so much-

David

Welcome.

I have rooted a different version of that Tephrocactus. It seemed pretty straightforward. Best to start with an entire branch rather than a chunk, so there's less exposed surface area down there, but obviously work with whatever you have. Cut cleanly. I have never used pruning sealer, don't know what that is. Usually I just air dry big cuts or dip small stems in rooting powder (mine contains fungicide).

Bury the bottom about half an inch, maybe a little more. If the stem is very tall then you will need to secure it so it doesn't fall over. Use a very rocky mix (eg. cactus mix plus pumice, about 50% rock total) and start out in a relatively small container. Wait a few weeks to water, and then water infrequently at first (say every 3 weeks through the winter). Give good light but not lots of direct sun (a sunny windowsill works great). The cutting should be fully rooted in a few months, at which point you can give more water and exposure and move it up to bigger accommodations, as you like. When you see new growth on top, you're out of the woods.

Your cactus looks to me like Pelecyphora aselliformis - very nice plant!!

Thanks for the info Baja, I don't think I have enough of the bulb(I don't know the used for each round section) deep enough in the media, which pretty much is what you describe. The sealer just closes up the wound much quicker, I have used it with other rootings.

Yep minime, that looks like what I want, now I just need to find one

Since I got such a fast ID, can anyone tell me what this one is? Thisis the other paper spine cactus I have.

Same species, different variety: Tephrocactus articulatus v. papyracanthus

Oh, ok. So the v. syringacanthus is much large with the paper spines 6 or so inches long.

Thanks agaain mimime,
