Trithrinax acanthacoma germination advice

[MobileBayGarden]

Hi y’all, I order some Trithrinax acanthacoma seed and can’t find any info on germination. Does anyone have advice about temps, etc? Thanks

Hi Philippe,

I germinated several seeds in a community pot left outside in the Texas heat back in 2017.  If I'm remembering correctly I started them in January or February and had sprouts in April or May (roughly 4 months).  Temperature probably ranged from Upper 60's to mid 90's F during the day.  I don't believe this species needs high heat to germinate.

Thank you for the info.

Pretty easy if fresh. I got about 70% from the baggie method in 50/50 coco coir/perlite at indoor room temperature (20-25C/68-77F). I’ve put the remaining seeds on bottom heat to see whether I can get anything out of the remaining 30% but seeds are now 18 months old so not expecting much.

Thank you! Very helpful!

I was curious about this myself when I read this thread last month.

Germination for me after about three months in a humidity dome with bottom heat that brings the soil temp up about 15 degrees. So heated to only 72 F peak daytime when I started it in the winter, now more like 85 F daytime (and cooler at night). 

I got this one as a freebie when I purchased some Brahea edulis seeds, and it sat around for a year before I began attempting to germinate it. No idea how long it was stored before it came to me. 

I likely soaked it for a day or two before setting it in the medium, but I wouldn't say it got any special treatment.

Trithrinax acanthocoma ( buriti-palito) is a rare native palm in araucaria forest in my state Paraná.  I germinated seeds in summer. Our temperatures in summer are around 20⁰ C at night and around ( normally 25- 27⁰) 30⁰C during the day.

I sowed some T. acanthacoma seeds in late Feb., but no sprouts as of late May. Tell me, did you germinate your seeds on top of the soil, or covered them completely with the soil? What medium did you use, potting soil , perlite etc.

George,

I buried the seeds about 1/2" deep in a mix of potting soil and perlite.  Seeds were quite fresh which seems to make a big difference.  If conditions aren't ideal (heat/moisture) it might take a while longer.  I sent my extra seeds from the same seed batch to a friend almost a year later and he got zero to germinate so probably doesn't have a long shelf life.

Jon:

Your method is the same as mine, potting soil and perlite. My seeds came from California and were supposedly fresh. I'll just keep wishing and watching for germination. Thanks for your input.

I’ve had mine on heat at a constant 85F for 2 months and still nothing. Do you think fluctuating temps would be better? I was worried about putting just setting them outside because we are hitting low 90sF during the day and low 80sF at night. Any suggestions?

Well, good news !! I finally got one seed to sprout. I guess the  June heat and rain helped. One down and about 299 more to go.

What’s temps are you at now?

I think fluctuating temperatures mimicking what they would see in nature should be ideal.  It seems to make a big difference in germinating Jubaea seeds.  When I use heat mats indoors I usually keep it between 90-95°F.  Patience is key!

MobileBayGarden:

It's late spring here in Northeast Florida, with daily temps in the mid 80's to low 90's. Seed pot is in direct sun most of the day.

I’m about 45 min from Pensacola so we are probably in the same ballpark. I’ll be moving those stubborn ******* outside tomorrow. Lol

Well, it doesn't hurt to try. Good luck, and keep us posted on your results.
