Just grafted some L. Williamsii and some A. Retusus to some opuntia stock. It's the last time I try and root pads on my own, I can get rooted pads for ridiculously cheap here so it's not worth the time/effort. One of the A. Retusus seems a little odd, just a bit bigger and has a weird formation that I haven't noticed in others.
Sadly one of the A. Retusus didn't make it (one of the "normal" ones thankfully) through the night because I was too lazy to use a humidity dome

So i got this seedling of Copiapoa hypogeia cv. 'Lizard Skin' and it is looking totally white...
ive only once had a totally white (albino) cactus before, it died when i tried to graft it after international shipping.
I know young seedlings can be all over the place with colors and pigments but i dont see how this guy is gonna be healthy and doing well without any pigment.
What do you think about variegation or albinism?
either way i figure it should be grafted sooner than later..

edit: i do think its an albino. thats crazy considering what the cultivar looks like.
will do my very best to both graft it later this week and tissue culture the rest. wish me luck

They look like Pachanoi to me, the one on the left has a v-notch at the top and the thorns and over all appearance screams tricho.
-- Had to run off before adding the rest of my post.  Some pictures of plants. :P
The Mammillaria are some of my first seed grown ones and now they are flowering. The graft is a mutated domino cactus, I managed to get two mutations from the same seed batch and intent to pollinate them to see if I can make mutant seeds. Of course, some Astrophytum Ornatum.

Maybe it's because they're young that they looked different to me, but I did start second guessing myself. They are starting to look more like Pach's the more I look at them...
Anyone else have any input?

They definitely look pachi though if your friend is growing them for certain purposes, the real question is if they are PC or not.

Thanks, y'all. I don't know the guy, or care if they're PC...I was just trying to help him I.D. those, but it seems I was wrong, and he was right.

Yowie Trichocereus and my misshapen barrel cactus. The barrel does not like it indoors at all.

Trichocereus validus grafted to Juul's Giant.

I'm a little desperate. I have a beautiful opuntia with vicious spikes I've been growing for 10 years. This plant has done great until recently. Looks like the veins inside the plant are turning brown. I've removed all the dirt, couldn't find any root rot. I figured it's probably some form of rot i just haven't seen?
Here are the symptoms:
-Tips of paddles wrinkle and then turn black shrivel and dry - cutting a cross section i see brown veins as well as green veins. Brown doesn't seem natural - the brown veins aren't soft, they are firm and brown - where the brown veins lead to, the surface skin looks like it boils a bit - all the paddles seem to have this brown vein running through it - if nothing changes it looks like the plan will die from the top down, not how i thought rot worked
After a month out of soil I gave it a little drink. I found a single paddle with no brown, so it's drying to save the genetics.
Pictures attached, will the brown go away or is this doomed?





As always any help is appreciated. Really bummed out about this one, luckily all my friends and family have a baby in their house from this plant, so genes won't die off. But still, this was my first cactus, tiny little cutting i stole from the university greenhouse, means something

I have no idea what causes it but if you have no other options, hit it with systemic fungicides to see if that knocks it out. I've only seen brown veins a few times but they didn't go through the entire plant I could pick it out with a scalpel. I recall seeing it sometimes when de-grafting.
If one or more systemics can't knock it out, then it's probably bacterial. Do the roots have signs of nematode infection, like nodes on them and do you get black specks on the side of a glass if the root is left in water?
The infection may just run its course and the plant will be scarred but not dead. If it doesn't affect all of the veins, then it might grow out of it. Opuntias are pretty hard to kill except for those bunny ears.

Do you have a systemic fungicide you recommend? Never heard of nematode infection, I'll need to look that up. Thank you!

Usually nematodes only affect the roots and block water and nutrients from reaching the rest of the plant. Unlikely the issue but possible, a microscope should be able to see them.
My nuclear options are Chlorothalonil and Thyomil.
Chlorothalonil is a non-systemic fungicide and some very nasty stuff, causes blindness, etc, if you get it in your eyes, so wear goggles when mixing. It also breaks down into persistent and far worse molecules, hence why it's a nuclear option.
Thyomil is a systemic fungicide used on ornamentals and not nearly as terrible but still, wear goggles while mixing.
There is no guarantee the problem is fungal but if it is, there isn't much these two chems won't kill. The Chloro is a topical and the Thyomil will work from the inside. It could be bacterial, even then, it could be that nothing can be done to clear it up and it just has to run its course for however long it takes.

One of my favorite old threads that I completely forgot about. Here is my Cereus peruvianus 'monstrose' growing in a patch of turmeric and papaya. Been in the ground for a couple years now, finally getting a good size.
