Ken, they will all leaf out comes Spring! Mine are doing the the same thing and I am not surprised, they simply going a bit dormant.

Ken,
If the leaves are turning yellow slowly and dropping off. This is more likely a dormancy period as Ursula mentions.
It is always nice to keep seedlings in leaf through their first winter (in climates where temps. lower and need to be brought indoors). Sometimes they will drop and very quickly start into leaf again, but let the plants be the gauge of this.

Thank you all for your comments. I thought I was failing with these plants. Maybe they are reacting to my back surgery and are showing sympathy.

Karen, mine are still sprouting, seems like each day a new one pops up, at 14 of 100 seeds after about 11 days. Hoping yours are just late to the party and start popping up for you soon! Nothing worse then patiently waiting for little seeds to germinate only to have a bunch do nothing. I'll add a picture when I get home tonight.

Thanks, Gerald. I do hope some more will come up soon. It is trying my patience, for sure!

Here they are as promised.

Wow, yours are doing well! Mine seedlings are much older and not as advanced as yours are. Only one of mine is standing up now with leaves. The rest are still bending over, staring at the soil. I'd say they're looking great, gerald!

Karen,
I'm wondering if you just got old seeds maybe? My seeds seem to sprout a new little guy everyday. How moist is you soil and do you know the temperature in the humidity dome?

So far only 6 have come up. I have no idea how old the seeds were, or how they were gathered. My temps averaged only 76 to 78F in the tent, and humidity never got above 50%. I'm keeping them constantly moist, but not soaked. I have them in AZ right now on the heat mat and in a bright window. I think they may do even better now.

It is more likely that the seeds where either old or not viable to start with.
I do not mean to sound negative, but for the time and anticipation of these seeds to sprout. I think that it is a matter of getting good/new seed and starting with them.

The germination ratios should be way higher, on average 3-10 days ( really not an average) max. Older seed can sprout erratically and take longer for seed to naturally break dormancy, but this is not something I would take the time or space with.

We all go with what we have and do what works for us. I just hate seeing you not getting the results that you could. It can be disappointing and make one cautious about doing more.

I just figure this gave me a bit of experience, and they were a gift. I will definitely buy seed to try next time. I'll have to research the trusted seed sellers. This hasn't discouraged me.

My first time with adenium seed was a gift and I think the seeds were old and I also didn't keep them moist enough from misunderstanding the technique. So this time around I had 100% germ of one variety and 50% on another variety. All are transplanted from egg cartons to little pots and growing well under lights. I'm doing weak fertilizer, not sure how much to give. Any wisdom about ferts?

This is my first time with seeds also. I planted fresh seeds mid December and they started sprouting within 4 days. I planted 72 and all
but 4 came up. Although the seeds came from the same pod, they have not emerged at the same time, some only germinated recently.

Originally they were starved for light. Not having a great location to start seeds, I had them in a guest room and we had unexpected company so they had to go outside, under a dome on a heat mat. The weather was cloudy for days and I feel a number of seedlings stretched up looking for light. They are back inside now under lights but you can see how some are long and skinny.

I had planned on distributing these babies to a propagation class tomorrow but they don't seem to have a lot of roots and I hesitated to transplant them under those circumstances. Do the rest of you find minimal root systems?

Thanks Ursula.

You are very welcome, Alice!
Your seed pod came from a group of cuttings taken a few years ago when the mother plant went South on me. This plant was a very tall grower and I used to keep it clipped at almost my height. I always thought that plant had perhaps some Adenium somalense in its parentage. I also have a regular obesum and a very small compact Adenium multiflorum Mombassa. All three spent the Summer on the deck and all three bloomed at the same time. So you might very well wind up with a small compact growing plant or a very tall and fast grower. Just like my batch and Ken's seedlings - it will be interesting to see how they develop. Mine are right now semi dormant as their parents, although they are warm in my very sunny greenhouse.

Ursula, Thank you, that makes perfect sense. Better it is genetics rather than my admittedly limited adenium parenting skills.

It's been three weeks since I planted my Adeniums and I have 20 seedlings. Some are definitely growing faster then others and I assume those that didn't germinate may not. Should I go ahead and take the dome off and just keep them on the heat mat?

Also when should I put them into pots? 4 true leaves? I should pinch off the top when doing so to encourage branching correct?

They look GREAT. Mine were planted in mid December and don't look nearly as good. Have you checked your roots? Mine have very minimal root systems and I am going to leave them in the cells until I see more growth.

@ardesia

I have not checked the roots. What's the safest way to do so?

Gerald, I would take off the dome and leave on heat mat. If it is warm enough in Florida now, the heat mat is not really necessary.
I like to transplant my seedling when they have 6 true leaves, sometimes I do when they have 4 if they are congested together.
Rick

I took the dome off and by the next day they all wilted. So I put the dome back on and misted them, and by the next day they were all perked up. I've been opening the vents on the dome little more each day until yesterday when I re-potted them into 4in pots. Only about 24 of the 100 germinated. I'll probably wait a few more months and then experiment cutting taproots and pinching off the tips.
