Trying to bump back to top so maybe someone can respond and help me out:)

Thanks, Jeannie :)

Jeannie, They seeds do not need full sun or much light at all to germinate in. Once up they can receive sunlight, but not magnified through a glass type greenhouse. The temperature should be 78F or a bit higher, if not using a heat mat. Keep a cover on them only until about 50% - 60% have heaved the soil. Then remove it. Make sure to take the lid off each day to allow fresh air inside dome. If living where humidity levels are high, it is not necessary to use a dome.

when the seedlings have a few true leaves you can introduce to high sun levels slowly.

Thanks Rick....I decided to bring them indoors until we get a ilttle higher night temps. I check the temp in the greenhouse (I had them on a second shelf not in full sunlight) and it was a little below 70%. I now have them on a heat mat (on a small box off the floor) in my breakfast area window and I covered them (the egg carton) with saran wrap for now. It get dampled sun in the morning and through early evening. I hope this was a good move. The day I planted them, we had hot days and nights and the next day (yesterday) was a lot cooler and the nights in the upper 40's:( We are suppose to have a few more cooler nights and then I will move them back to greenhouse in a shadier area. I received the seed from Maria Elena and I want to do my best to germinate them. Maybe I worry too much!

Thanks, Jeannie :)

Jeannie, don't worry. You can keep them in the warmest room in your house if it makes you more comfortable. Just don't let them get cold or dry out. As Rick suggests, covering with Saran Wrap will boost humidity but be sure to uncover during the day to allow air circulation. Also, spray 2-3x a day ... keep moist but not soggy. I believe they will do just as well where you had them in the warmer greenhouse but need someone else to chime in in terms of the high temp.

I germinate mine outdoors under full tropical sun ... It's how they grow naturally, right? I find I have better germination this way and believe it's heat that's most important to germinating these.

Please, no stress. I'm hopeful for excellent germination on your first try but know where you can get more, just in case. If you'd like to see photos of your potential blooms, click on "Adenium" at the top and skip over to eeyore oregon's KO Seedlings thread.

Always feel free to reach out. We're all here for each other.

Maria Elena, do you cover or use a dome when germinating? When I lived in DC, I did with seeds from Laura & they germinated. Here in Mexico, I've used domes & covers--outside on the balcony during the day & inside on top of the DVR, etc., at night (lows drop to 69-65 some nights) on seeds I bought online from a reasonably reputable supplier here in Mexico (importing is a huge hassle). It has been 22 days now & only 1 of 15 germinated. When I lived in Miami, I didn't grow DR, so I can't compare.

So... bad seeds are a possibility. Or maybe with the tropical sun, I'm cooking the seeds by covering? I do remove lids/domes periodically, and I'm always checking for growth. Possibly I shouldn't sow in gritty mix, but instead move into gritty after they've established a bit? (My gritty mix is what I can find locally in Puerto Vallarta & is not a true Al's mix. I think my pieces are a bit large.)

Any thoughts?

i know I jumped in on your thread, Jeannie. Sorry. I've been meaning to ask Maria Elena because her growing conditions are closest to mine (unless anyone here is in Honolulu, which has a similar climate to Puerto Vallarta).

Hyn, do you place another wet paper towel on top or just the one beneath the seeds? About how long after germination do you transfer?

Over top too. As soon as I see the roots coming out I transfer them to the domed flat right on top of the damp soil without covering them. The seed coats are really easy to slip off at this point as well since they'll be fully saturated and not half dry.
The tap root burrows right in literally within a couple of hours to start lifting the seeds upright. I wear 'Gloves in a Bottle' for this as they are toxic plants, then wash up.

I think I'll try your method, Hyn. Thanks :)

Direct to soil works well too. Not knocking it. I just like this option to see everything that is going on and it was recommended by 3 of the 4 sellers I got seed from so I thought it worth trying. Worked great.

Patty, I'm glad this process works for you and helps you record accurate germination data. That said, I do not personally recommend handling fragile adenium seeds like that. Especially not something I'd recommend to Jeannie & other newbies. The "bag method" is better suited to big, sturdier seeds, like plumerias. In fact, I've successfully germinated plumeria seeds in 3% hydrogen peroxide using the bag method but found that the chances of damping off still exist once the seed is transplanted.

Ariel, my apologies ... Your message just came through a cyber hold.

From my own personal experience within my environment (avg daytime high 82 (winter)-96º F (summer), avg nighttime low 68 (winter)-88º F (summer), avg humidity 78-86%), here are my recommendations for sowing seed:

Jan / Feb overnight temps are too clammy to plant adeniums, which need a stable high 85º F. I sow in sterile Seed Starter mix ... it's like a pillow and there is zero damping off. Fill container, spray with water, place seed flat, sprinkle more soil to just cover seed, spray again. Spray 3-4 times a day to keep soil moistened but not soggy. I place my seed trays outdoors in direct sunlight. This does not harm the seeds at all and the warmth of the sun helps germination. Around 6 pm all seed flats come indoors to my hottest room. I see lots of overnight germination.

I am not a fan of community pots ... Each seed gets its own "chamber." I do not cover because the purpose of that is to increase humidity. My humidity is already too high. When I sowed my very first two batches of seeds, I was wrongly advised to cover them at night and uncover them during the day. That's fine for arid environments. What that did was cook my seeds. The point is culture ... You have to do what works within your climate and your growing conditions.

I am so grateful for all the marvelous folks on this site who helped me figure things out over the course of this past year. My very first adenium experience was a successful air layering. Imagine that! These plants (trees) are amazing. I don't think we'll ever stop learning from each other ... or from them.

Maria Elena

I'm thinking that, except the one that germinated, I cooked the seeds. Well, I'll try again! Thanks for your suggestions, Maria Elena. Our conditions are fairly similar. I may even try a couple of different ways.

Please share your results, Ariel ... Not on Jeannie's thread, though, LOL.

Jeannie, apologies for hijacking your thread. How is your germination coming along? Did you keep them in the house or move them back to the greenhouse? Are you holding your breath and waiting to exhale? LOL ... You should see them begin to pop any day now, say Tuesday-ish! Please share when they do.

Maria Elena

Haha, I don't think these big seedlings are very fragile. Not at all, compared to the tiny things I'm used to handling. But to each their own. I only wished to mention another method should anyone care to try it. ;) Otherwise I entirely agree, there are lots of ways to do things and it's only a matter of figuring out what works best for you in your particular situation.

I'm still waiting for them to pop through the soil:( I think I see a few trying to come through....I put them back out in the greenhouse during some days when it was a bit sunny, but we've had rain/clouds for the last 3 days. I have them back inside and back on the heating mat.

Thanks for all the help, Jeannie :)

You're taking care of those babies like a mama, Jeannie. Any time now! Keep them moist.

I think I heard a seed say...."I think I can, I think I can, I think I can :) I see a tiny bit of green :)

There are 3 others that I think may be the tops of the seeds?

They are still the same. I wonder why the one decided to pop out of soil before these 3 did? They are all in the same egg carton.

I'm really trying to be patient! We have more days of cloudy and cooler weather. It's been around 75-82 in my greenhouse (only some days when some comes out a bit), but I've been keeping them inside the house every night. I put them on the heat mat every morning until the weather is warm enough and I bring them out to the greenhouse. I hope I'm doing things right! Thanks, Jeannie :)

You're fine Jeannie. They are all different seeds for differen plants / flowers and have different genetics. It's Tuesday & I called it, right? Ha ... Sending good vibes your way for excellent germination.

Maria Elena

Hello Jeannie,

Where are you in Texas? I am in Dallas and I started growing from seeds last year so I'm pretty new to this but I've had 10 successful trays so I'm content with that. This is what I do. I place the seeds in a 72 cell tray. About half an inch deep. Then I water each cells. Once done, I cover the tray with the plastic dome and place the tray on a heat mat. I also put a piece of foam under the tray and the heat mat so that I don't lose heat. Temperature averages 80 to 82 in the soil.

I gently water once in a while to keep the soil moist.

The tray is also in my greenhouse all day and night. After about 3 days, I can see a few of them peaking out. And after a week, they are all out.

I learned a lot of the people around here so I'm sure you will too :)

Stephane

Hi Stephane,

I'm between Houston and Galveston (close to Clear Lake area). Thanks for all the info. We have had cloudy/rainy weather for the last 5-6 days (more days to come like that) and I wish I would of waited a little longer to plant the seeds. Thanks, Jeannie :)

Well, I finally got enough yogurt cups (lol) to transplant my 5 babies that made it from the 12 original ones. No really, I just took the time to finally transplant them. I have been fighting spider mites that came on my last order from the Ebay seller I was buying small Adeniums from :( Plus I have tooooooo many plants to care for!

Here they are:

Happy Gardening, Jeannie :)

They are looking great, Jeannie. So happy to see some survived those tricky, cool, clammy days. Each one is for a different bloom, so you will enjoy a lovely little adenium garden with these next spring/summer. In the meantime, enjoy watching them grow into fatsos.

One of my 11-month-olds, grown from seed, is blooming. Can't wait to meet those flowers! It was from one of my first mixed seed packets, so I have no idea what it'll be ... Probably another single pink ;-p

Maria Elena

PS: Please get some Triple Action NEEM Oil (Southern AG, $10/8 oz), broad spectrum fungicide, insecticide, miticide for those spider mites. Mix 1 tblsp per gallon and spray everything (plants, underside of leaves, and surrounding area) around 6 pm when the sun is setting. In the morning, before 10 am, rinse off everything with a hose so the remaining residue doesn't cause leaf burn under full sun. Repeat every 3 days until the problem has been eradicated. Godspeed.
