Eucalyptus dalrympleana Seed Germination Advice

Recommended Posts

PalmTreeDude

I have around 50 Eucalyptus dalrympleana seeds that I had in the fridge cold stratifying for at least eight weeks now (maybe longer, I forgot exactly) in a damp paper towel. The seeds are super tiny. I was going to germinate these in a little closed container just on top of some moist soil. I heard they can germinate fine at tempatures around 65°F. Does anyone have any advice about germating these? I never germinated Eucalyptus seeds before.

I’ve done it with success. I put the seeds in damp community pots with fast draining soil  and then sprinkled with fine sand to cover them.  The pots were then covered to keep the moisture in.  8 weeks in the fridge and then brought out and germination wasn’t too long after that. The seedlings are tiny and kind of weak so keep a close eye on them and expect not all of them to make it. When you transplant them don’t disturb the roots they are very sensitive.  Also eucalyptus don’t do well in pots so get them in the ground early - growing them out in pots to a larger size is a detriment and can really set them back. 
 

The fastest growing one I have is perrinianna. Went from 1’ to over 25’ in less than 3 years.

Thank you, I actually just took mine out of the fridge and put them into a container. They were so small, I tried to get as many as I could on top of the soil. Then I sprinkled a super thin layer of sand over them. I'm not sure how old the seeds were when I got them, but I'm hoping I get at least one or two, but we'll see if I get any.

Good luck.  If they sprout they are miniscule.  

Look up BocaJoe on Youtube.  He shows some Eucalyptus growing in Virginia.

Yes! Looks like some of the seeds were good after all. These just popped up.

Good job. They’re tiny alright.

Nice- I actually sprouted my dalrympleanas without stratification. Sites I read said you can but you can get decent germination either way. 

RPS only gave me about 10 seeds each of the Eucalyptus species I ordered so I had only 2 that ended up making it to maturity. One mysteriously died after planting in ground, and the other I planted in ground but has been stunted and gets leaf fungus (back in Northwest FL).

Would definitely like to try growing them again, especially considering the success someone else here on PT has had growing a very healthy specimen in South Carolina. The dalrympleana is one of the best looking Eucalyptus species IMO.

Some require stratification some don’t. I have five species in the ground and my favorite is the first one I got E pauciflora “niphophila”. Can’t beat neglecta for the smell though, they smell amazing when it’s hot or after a rain.

      I was curious how long it takes to sprout Dypsis prestoniana seeds using the baggy method.  I did the float test, cleaned a bunch of sinkers, used a little bit of hydrogen peroxide to give them a final cleaning and then put them in baggies with some moist sphagnum moss I have for mounting orchids.  I'm sure someone can weigh in regarding their experience and timeline on sprouting this species.  I started those baggies on 12/1/2020.  This evening I did the same with about 50 Dypsis heteromorpha seeds so would be curious about others experience on timeline and yield for them as well.

      For sale is the total crop of seeds of an unknown dwarf Sabal minor. I germinated this palm around 2008 from a seed sent to me by a PTer I can no longer recall. Where he got it I don't know but he sent it to me as Sabal etonia. I learned years later it is actually S. minor. That makes sense to me because actual Sabal etonias never survived for me. I planted it in my Caribbean Garden in 2009. During the 12 years I have had it, it has grown painfully slowly to its current size of 2' tall x 3-4' wide. I has flowered for years but produces crops of sometimes fewer than 100 seeds. This year's seed output is <200 seeds. It is a compact grower and should be cold hardy as any other Sabal minor.

      Hi all,

      I finally received seeds I ordered from rarepalmseeds.com here in Aruba (small island in the Dutch Caribbean).
      I would very much appreciate some suggestions on methods for germinating and care after the germination. I will keep updating the thread as they grow for future references.

      Below are the suggestions I'm most eager to learn about of the seed type (Euterpe Oleracea, Açai Palm)
      Soil Medium for germination? (perlite, peat moss, coco coir?) Soak in water? (how many days, fungicide bath?) Does the sinker/floater test apply to these seeds too? Heat mat? Depth of Pots and soul medium after germination?
