So I planted these Cereus aethiops peruvianus seeds that I made from my own plants, and when I checked on them yesterday I was really surprised.

Magenta seedlings!

Does anyone know what's going on with these funky magenta seedlings? Should I give them any special care? Will they turn green or will they just die if I don't graft them?

Usually redness is an indication of high light levels, but they're more pink ! Wouldn't think they'd all be variegates so I'd assume they'll revert to green in a few days.

Could also be a reaction to something in your mix perhaps ??

What an amazing color!
Would be great if they kept it.

Good luck!

The seedlings are in mostly shade and under translucent plastic. The medium is pure washed and sifted river sand with some liquid cactus fertiliser added when I planted the seeds.

So someone spotted the green one. It's pink now too.

Hey Cereoid,

I have herd not to use any fertilizer at all when growing cactus or succulent from seed and i never had.

I have not come across any pinky seeds like that before.

Possibly something to do with that?

Then again it could just be the Cereus aethiops peruvianus seeds you have.

Could be the fertiliser - might have something in it at a high level that's effecting the seedlings. Really no need for fertiliser until the seedlings have established themselves. The root hairs are extremely fragile/sensitive at germination, so probably prone to be burnt off by too much chemical fertiliser anyway.

I figured that the fertiliser wouldn't do any harm since it is a low dosage and going into something with no nutrients to begin with. It would likely be a lower concentration than if starting seeds in straight potting mix.

The root growth looks really strong so I don't think it's damaging them much if at all. They have a main root that is about as deep as the plant is tall (or at least they did yesterday) and lots of root hairs.

So there's no organics whatsoever in the mix ? Sounds like it's almost hydroponics! If so, I think you'll find it a bit of a struggle to keep them going, but Cereus are pretty tough so maybe they'll come through... Good luck with them!

Even if they all die then that's only a small percentage of the seeds in storage! And I can get them indefinitely in the future whenever this happens:

like said.

i have always used a pre assembled seedling mix from bunnings. all i do is sift out chunky stuff from one or two handfulls of mix that i put ontop of the unsifted mix to put the seeds on. always sprinkle a fine layer over the top. cook in the oven or microwave. microwave seems to work fine and takes a couple of 60 second rounds.
never use fertilizer.
seedlings are like babys. they are being exposed to elements for first time... they have zero imunitys. to much light... no good. to much water... no good. fertilizer... no good!

fertilizer is good for plants. bad for seedlings.

it will alter the way the seedy/baby developes immunity... not good.

now that you mentioned the fert... either the seedys just have a pink phaze... or they are overdosing on something in your fert.

still dont give up on em. they could/ will turn out fine if you are a good parent to your babys.

ps. some people get very pedantic about seedling germination techniques... remember. it aint rocket science. mother nature does all this w/o kitchens, chinees t/away boxes, heat mats and artificial lights... she keeps it real y'all. and she is the pioneer that gives us the most important ingreedient for us to have a go.

dont over complicate things. keep it simple. keep it real.Wink

Well after some time they have grown bigger, grown their first spines and have kept their weird colour. But there's this one really weird one in there as well. It has three cotyledons:

Does anyone know what's going on with this one?

Unfortunately I have no knowledge to impart.
But I will say wow! Amazing colour which they seem to have kept well this far and they look extremely healthy.
Thanks for sharing the update, the photos are so clear.
I can't get pictures that clear of my seedlings because of the cling wrap covering the containers.

I keep them in a clear plastic bag that I take off when I want to inspect them or take photos. But it was still hard to get those photos because the camera only has auto-focus and kept trying to focus on the sand, so in order to get those photos I got it to focus then moved back slightly to bring the seedlings into focus. It is a very delicate process and requires extreme precision or taking a lot of photos. I did the latter.

Might have to switch to plastic bags next round of seeds I plant. Currently use glad wrap and its impractical to remove it, take a look at the seedlings and rewrap them.
If you you ever have any excess seed you'd like to sell please let me know would love to try my hand and the pink beauties.

Cheers

Sorry I didn't read the entire thread Embarassed

However this could be food for thought.I have had 2 different species of columnar cacti in the same tray under the exact same conditions, all of the seedlings of one species turned red/pink whilst the other remained green. The species were Pachycereus and Trichocereus... Weird ?

HN you didnt specify whether or not your pink and green seedlings grew on to become healthy normal plants?
did they all turn out fine? im thinking they probably did cause you probably would have mentioned any significant issues you found with your "pinkys".

walker just remember the potting arangement incl glad/plastic wrap is being used for the seedlings interest. not your camera. while its nice to take photos of seedlings and look at them frequently, doing such does not give any real benifits. chances are if you get your medium/water mix wrong by the time you realize...
we just work on getting the medium right, sterilize soil and wait for seedys to sprout... easy to see even through the water droplets and mist on plastic wrap, once seedys are go... hardining off. thats when the glad/cling/plastic wrap makes life easy!
it dont take long once peircing one or two holes "if your mix is on heat" for the misty fog to dissapear.

opening sandwitch bags frequently for camera shoots only allows room for contagens and unwanted contaminants. yes.

use plastic wrap.

my tip to all. get a lead sinker "fishing" or a heavy marble and press down lightly in center of wrap when first aplying the wrap. let it sit on the plastic from here on. the weight will make excess water condensation collect and run to a low point easily so all you do is tap the weight a couple of times and....

Yes I'm sorry I should have said that. All seedlings I mentioned above were grown out and they are all normal and green and growing fine. It took about 4 months for the discoloured seedlings to revert back to green. I guess this all points to a chlorophyll issue ?

I should also point out the seedlings were grown under fluorescent lights in a controlled environment, where they receive no natural light or wind.

I checked in on them recently and found that the tricotyledonous one is not alone! I have two!
