Good afternoon, I have a few seedlings leaning like this and now it's time to pot up. Should I plant at the same depth, lower, and should I straighten it up? Any suggestions? This will be my first time potting up Adenium seedlings.
TIA, Joe

I would say plant at the same depth and as is. Angel

I did straighten a few that were leaning like that, I didn't think it would hurt. It seemed initially they had more top growth than roots to hold it upright so the slightest thing like a hose spray or even wind could cause them to lean. Mine finally have enough of a root system to hold them in place.

If they are leaning it could be because they aren't currently deep enough for the roots get a good grip and hold themselves upright. I had a number of them like that when I started a bunch of seeds earlier this year. I would straighten it when you repot, and also repot it slightly deeper - just enough so that I can support itself erect. At this small size that may only be 1/8" to 1/4" deeper.

I think leaning in these little guys has a lot to do with the culture vs. nature of the plant. Seeds are generally planted very shallow in very loose type soil. The chubby little seedlings are very strong, and when they germinate, the tap root tends to push the whole thing up a little before it gets a good grip and starts growing down. The result is a seedling that you have a seedling that is a little top heavy and therefore leans a bit. Simply potting a tiny bit lower when repotting alleviates this.

Alternatively, looks like you have a little extra space in the top of your cup. Looks like you are using 100% vermiculite, right? If you aren't ready to pot up just yet, you could gently push it upright, drop a little more dampened vermiculite around it, and sturdy it a little that way.

Carter, The mix I used one this one was 2 parts potting, 1 part grit. When I planted the seed I covered them with 1/8 inch vermiculite. I am now using what I call my 3G mix, (3 grits), 1:1:1 pumice/#2 cherrystone/zeolite. I am happy with this mix (shown in the photos below) because it adds weight to the pot and allows plenty of water and air flow to the roots, and being almost impossible to overwater.
