Acrocomia crispa germination

Recommended Posts

Recently acquired some A. crispa seeds and cracked the outer shell (I’ve heard it helps shave lots of time off germination). Does anyone have success with any specific methods or know how the endocarps themselves like to be treated? Any advice  would be much appreciated!

If seeds are fresh, I've germinated A. crispa in less than a month, in hot summer heat. They are not at all Like other Acrocomia seeds (which take years).  That's why I keep calling mine Gastrococcus.

I had access to minimal seeds and I tried cracking the shell and just planting.  The only one that germinated for me was an uncracked seed.  After cracking I noticed that they all floated so they might not have been good in the first place.  Like Charlene, mine germinated in the heat of the summer after about a month.

Got 12 seeds from RPS in December 2018. Let them soak in water for nine months (till Sept 2019) before doing anything with them (did not expect any success). Used pliers and a hammer to remove the thick shells and sowed the endocarps in potting soil. Being Hawaii, temperatures moderate, never hot or cold. Two germinated, one in 21/2 months and another in 6 months. Both now individually potted up and growing well.

Wanted to add to this for posterity.

I got 35 A. Crispa seeds from @Bigfish a few weeks ago.  I didn't initially soak as I wanted the shells to be as hard as possible.  I cracked all 35 by holding with a pair of vice grips and taking some measured whacks with a trim hammer.  I nicked a few unfortunately, but didn't outright smash any.  Afterwards, I soaked overnight in tap water, then briefly soaked in hydrogen peroxide, before laying on top of a "sanitized" (microwaved) bed of damp perlite.  The first 2 nights they sat on top of my cable box, after that they went into my shed (we are still getting 90 degree days here just south of Houston).  They went into the perlite on 9/29 and I noticed the first few popping yesterday 10/5, so only 6 days until germination.
