Mexican Giant Dioon (Dioon spinulosa) seed care

Recommended Posts

I received three giant dioon seeds from Seedman.com today, how do I properly germinate them? Do I soak them like palm seeds? They are massive, like the size of small eggs, and I hear rattling inside when I shake them.

This is what works for me. Soak seeds in water for 2 days. Place sideways on damp pumice, at a temperature between 28-35 degrees celsius. Once seeds germinate pot them up in pumice.

Did they float or sink initially?  And what about after their soak?  I don't like being the negative one, but usually rattling isn't a good sign. It doesn't mean they aren't viable, but their chances are better if the interior parts haven't separated from the exterior shell.  I think it means they were allowed to dry, but could be incorrect.  Sorry for the poor terminology.   Again, not trying to be a downer, just trying to help understand if germination doesn't work out.

I started soaking them this morning and they all initially floated. So far, however, one has sank to the bottom of the cup they're in.

      An untagged potted cycad is dropping ripe seeds in my back yard jungle. I suspect it might be a Zamia but what species or hybrid I don't know. It is not a Z. furfuracea ("cardboard palm") nor a coontie (too large).
      Can anyone tell me even what it might be? Is anyone interested in the ripe seeds? The fruit/seeds are about 3/4" long and 1/2" wide. Thanks.
