Lesions on Lophophora williamsii seedlings

[MagiCarpus]

**UPDATE**

I've given them some shade ever since they turned purple/brown and acquired wrinkles. The hypo-pigmented lesions brought up in the first post have become more obvious once the rest of the plants darkened in colour. Should I be worried about them? As far as I know these white patches are not spreading or getting larger. Overall, how are they doing? what more could be done?

They look fine. The patches have scared over by the looks of it and there is new health growth in the centre so they look fine. My lophophora seedling also tend to look a little more purple as well but it's just narural colouring with good lighting.

Here are my two oldest lophophora williamsii seedlings. They are toughing it out with the big boys in the green house this winter so have not had any water for about a month and a half. Come spring when they start growing again they will come back green and swell up again.

Wow, those look so much more rugged than mine. It goes to show how tough these plants can be, thank you for sharing them, it's inspiring and reassuring.

**UPDATE**

First update of 2017 brought some unexpected development, and I'm not sure if these are good signs...

New plants were "birthed" from the "shells" of the original seedling, as you can see from the pictures. Some look pretty wacky as if the new plantlet was stacked on top of the old plant. Please help me shine some light on this phenomenon.

Given enough time to grow, will the new plants completely replace the old plants? or will I be stuck with unsightly specimens that reflect my previous mistake?


Cute...




peekaboo?

They will grow out of this weird shape and in a few year you will not even notice. They are just growing new heads which is comon when they get damaged. It a sign they are growing fine.

[MagiCarpus]

That is good to know and a relief so thank you. I'll keep updating their progress.

Quick update on the seedlings.
Recovery had been slow but I was happy to see plants that finally resemble the classic look.

[adetheproducer]

Yes they look great now much much better well done.

[MagiCarpus]

Thanks Ade! I appreciate all the inputs you gave to get them through such crisis at the mercy of my amateur hands. I look forward to the day I move these updates to my normal seedling thread.

Congratulations. I have never even tried to grow cacti from seeds. Your plants look good!

Do sciarid fly larvae cause lesions like this?"

Nope the larvae would eat the entire seedling from the inside out. some kind of fungus I would guess caused the white spots.

Seedling look way better now. I have used root tone a powder with fungicide in it when I have trouble like you did. Drop it on the seedlings with a very small spoon , flat stick, whatever tiny tool you can find.

Next time more mineral, pumice, lava rock whatever and less of that black wet soil, maybe like 10% soil. I use plastic for about 4 weeks then take the plastic off at night for a few more weeks then no more plastic.

Great to see the improvement. I did have some success with L. williamsii from seed, years ago. Unfortunately I was not able to keep them viable past the seedling stage.
