Hi everyone!I have two seed in vermiculite, they sat for about 5 days in peroxide solutions and germinated very fast.
So I put them in vermiculite but I can't see any sprouting. 12 days have passed. I peeked under the vermiculite and I saw the seed almost broke in two parts and a long root (I think). The seeds that germinated the past year took only a week to sprout. Is it still to consider normal? Or should I check better the two baby in the pot?
Many thanks!

I noticed when I was testing different methods that seeds which appeared to have germinated in H2O2 sometimes took a while for sprouts to appear after planting. I'm not sure why, whether the germination stalls after they're taken out or what. Stratification is more reliable for speeding up germination than soaking in peroxide. Were the others that only took a week those that you stratified? I'm not really visualizing the two parts with a long root, any chance of a photo?

@sooby, I guess something went wrong. Here some pics.
You can see how the part still with the seed around is brown... now, while moving it, one of the seed detached from the white/green part. I guess someting is not right.
Could you help me identifying the parts and their names LOL I don't know if it's root or leaf that white part that is going to say bye to te remaining of the seed!!!!!

Now we are at 16 days since germinating.
The other seeds I'm growing where in peroxide too and took a week to sprout.
I really think these are dead. Or not?
Thank you!!

It's hard to tell exactly but in the first pic it looks as though the sprout is still attached to the embryo/cotyledon, which has turned brown and seems to have a bit of fuzzy mold at one end. The brown thing shaped a bit like a bottle is the embryo/cotyledon. I'm not sure why the shoot was brown at the base, so there could already have been something wrong, but there definitely is something wrong now that poking around has detached the shoot completely. There should have been a root first before the shoot grew. My guess is that the seed became infected with fungus and rotted. Is there any sign that there was ever a root?

This is a daylily embryo taken out of its seed, yours looks the same only brown:



This is what a germinated seed should look like (I took off the normal black coating to make it germinate faster so pretend it's still there The long white part on the right is the root, the light green part emerging on the top is the shoot:

Thanks Sue. I guess they rot. They were in vermiculite and I put the pot over a shelf, just above a heating element I thought heat would help. But since there was heat I watered more than the first seeds I planted the past year.
I killed two poor seeds, a seedling, maybe another seedling will die from too much water... I'm really a disaster.

No, not a disaster, just learning the hard way like we all do. I'd be surprised if anyone here has never killed a plant or had one commit herbicide 😄
Best way with seeds is to dampen the medium, sow the seeds, cover with clear plastic depending on the container size and then you shouldn't need to water until the first one comes up and you take the cover off. Then comes the hard part, which is knowing when to water. Over-watering is far more common than under-watering and watering appropropriately is about the hardest thing to master in gardening.

I'm letting the soil in the pot dry... There is another seedling that is at risk. I really hope it will make it. In the meanwhile I put some other seeds in peroxide, the two in the pictures are definitely gone. I'll try to learn the lesson, many thanks for your help and support!

Sabrina - I agree with Sue. I think probably most every gardener has at one time or another killed plants. I know I have.

My rule of thumb is to water once a week any seedlings. And I have a warm climate on a sunny windowsill. So if you aren't getting lots of light, then even less watering. Rot kills a lot of seedlings.

I have faith that you will discover what works for you in your climate and environment. You have folks here that are giving you some excellent advice. Don't get too discouraged. It's a learning curve. You'll figure it out.

Thanks girls, you're very kind!
I just put other two seeds in vermiculite paying attention to not water too much (I used a spray bottle) and using a plastic box with its lid on it. Fingers crossed!
