Is this Damping-off?

[Vik250]

Hi all,

Is this what one would consider seedling damping off? If yes, what can I do to resolve it, if anything?

Also check them stems and their color. Could it be some type of infection? Any good fungicides I can buy if not for these then for future as a precaution? I checked Amazon but got very confused there.

Thank You as Always!!

What aspect of the trunks should we look at? What color has you worried today?

I can't see any sign of damping off.

The picture with 2 seedlings, they have brown/dark greenish stem at the soil level. The picture with 1 seedling is just sideways and looks like about to fall off.

At some stage the bark will have to change color to darker, mature bark. That should be happening about now and that's my best guess for the color change.
As for leaning sideways that's usually just that there's not many roots on one side.

Ok that makes sense @Shibui. I have just 1 last question if you don't mind (even though I mentioned it earlier in other threads in previous weeks). But now that I understand a little more, I want to ask this question - The 2 pots you see, well the soil is not actual soil soil*. I broke some peat pellets and used that soil only in these pots and these Flame Trees are growing vigorously under grow light (I never put them outside or direct sunlight- FYI). Now I am wondering that if I want to transplant these, for which I do have bigger pots that arrived 2 days ago, would it be OK to use Seed Starter soil in this big pot? Or should I mix my bonsai mix with the seed starter soil? (I read in one of the treads that substrates such as bonsai mic should only be used when one has an actual tree [Yes - there is no such thing as a Bonsai mix soil but just saying what it says on box. Below is the picture of stuff in it]. SO, HOW DO I TRANSPLANT these and what soil and/or substrates do I use? Also, is it OK for me to put 2 seedlings in same pot?

Thank You Everyone and especially @Shibui

Soil is another subject that ignites hot debate among plant growers. There's lots of different opinions and they all seem to work which means that there's lots of right answers.
The truth is that plants are resilient and can cope with a range of different conditions.
seed raising mix has very few nutrients. It is good for germinating seeds but not always the best for growing larger plants.
Your seedlings can go into the bonsai soil.
They could also grow well in a mix of bonsai soil and seed raising soil.
Provided you add fertilizer they would also grow in seed raising mix.
There is no one correct answer.

Each different soil will require different watering to maintain the correct moisture levels for the plants and that can be tricky when changing from one soil type to another but the larger pot usually allows some leeway to get the balance right.
I generally transplant seedling straight into the same soil I use for all my growing trees and bonsai because it is simpler to just have one soil mix. Then I manage watering and fertilizing to suit that soil and get great results.

Thanks a lot!! That answer helps and explains a lot. I would transfer these in same soil as you would (seed starter mix), lol, but I don't think it would be wise due to low nutrients. Nevertheless, I'll transplant 1 or 2 in seed starting mix and the other one in seed starter/bonsai mix to experiment. I just ask this question primarily because you know the Roots on these Seedlings are very delicate and I feel that if I put them in this Bonsai Mix (the picture attached above), chances are they will get obstructed by the stones of all kind and won't be able to spread. Let me know your thoughts on this? I know there is a lot of Grey Area in this profession due to various variables but I like to hear from experienced members like yourself. At least that provides a better shot at survival for my seedlings/plants and that matters a ton in my opinion.

Also, when you mentioned I can mix seed starter soil with bonsai mix that I posted above, you mean I should actually mix it thoroughly and then use it or use these in layers? If mixing these, what is proportion you recommend? (I.e. 50% of each, etc etc.). I know this is not easy to answer but give your best guess. It's my responsibility and I won't blame anyone if things go awry. Matter of fact will learn from it and not give up on this passion and hobby.

Thank You!!

Roots are not obstructed by stones. Roots grow in the spaces between stones and around stones. The benefit of larger particles (stones) in potting soil is to maintain air spaces that allow roots to be healthy. Your trees will be quite happy in the bonsai soil without any seed raising mix in it.
Roots of seedlings are not as delicate as we think. They can break but are also programmed to grow fast so broken roots just result in many more roots growing to replace the broken ones.
When I repot seedlings I almost always cut the roots to stimulate more root growth.

If you intend to use both soil types I think it is better to mix them thoroughly. having different layers in a pot can interfere with water passage and with root growth as roots don't seem to like going from one soil type into a different soil type.
note that I said it is possible to grow seedlings in a mix of soils but the bonsai soil you have purchased has been specially made by experienced people because it is a good soil to grow trees in pots. If they believed it was better to have seed raising mix added they would have done that.
My first preference would be to transfer the seedlings straight into the bonsai soil but it is good to see you planning to try some different things to find out what works better for your trees in your conditions.

Thank You so much for everything. Very much appreciated

No, the base would be rotting out and the top would slowly die. Leaves look healthy to me.
