Seed Starting- Carpinus, Larix, Sequoia

[Jzack605]

I have some seeds in my fridge I collected from a private arboretum last October and was wondering if anyone had any suggestions on best method for germination.

Larix
Sequoia sempervirens- this tree was large and growing well in zone 7, so I’m mostly excited for this one.
Carpinus

for the Larix and Carpinus, they have the protective layering; are they supposed to be removed?

does the water trick for all these species work?

Any stratification/scarification necessary?

thanks!

Carpinus Betula?
for dried seed I followed the sellers advice and was successful with the shorter times ....probably 30% success after planting bout 100 or so seeds.
Greener seeds require less time....here are both circumstances sellers instructions.They are very knowledgable.Also an overnight soak in kelp works wonders at the start....

I think they are betula but I have to check the bag when I get home.

If I collected in fall, dried and put in fridge; what would the warm stratification prior to 120 days of cold be?

30 days is good.

i am actually starting Carpinus Koreana this evening

That is new seed so probably 30/90 is good ...how much seed you have.......if loads,90 should give enough.Seeds are great to get the genetic variabilty.

So what is the process? I’ve had them in the fridge since October. Can I just put them out at room temperature for 30 days and then return to the fridge for 90?

Are these dry in the fridge? Or moist?

I would expect them to start germinating as soon as you plant them in a moist medium to be hones. But I do not know. Be interested to see. Following.

They were collected and dried then placed in zip lock bags in one of the drawers of my fridge.

I would like to keep it as simple as possible. So simply sowing would be great. Though I assume still soak for 24 hours to see what’s viable.

Kelp is not essential,so water for 24 hours in cup .......use orchid spahgnum as it molds less.Put in bag of moist orchid spahgnum so seed is about 20% of bag.Squeeze excess moisture out of bag till’ last few drops...err on side of drier. Keep at room temp or slightly warmer maybe on top of fridge for the warm stratification.Then into fridge salad crisper for the cold stratification....I never had much issue where the mold forms....just plant with the mold(if any from the warm bit) orchid spahgnum resists mold the best...nearly none when cold stratifying.
