Phoenix Dactylifera seeds not giving up the goods?

Recommended Posts

I have previously sprouted date palm seeds with the method of them wrapped in a wet paper towel, stuck in an air tight baggie, and putting them in a nice, hot window. They sprouted beautifully! We have since moved, and I am working on the same thing now, but with a heating pad instead of a hot window. (My house is about 70 degrees at this floor of the house, so I do need the extra heat.) 

The only differences I can think of are that I did pre-soak the original seeds for several days or possibly a week. I forgot to soak these ones. Also, the window had sunlight, but the heating pad does not. Not sure how much sunlight could penetrate a wet paper towel, and anyway, I thought they needed dark to germinate. 

What do you think?

You must be careful with heating pads. Putting them directly on can fry them. The pads I use have a temp sensor   I place a plastic plant tray on top of the mat then the bags in that. I put the sensor inside the bag and it will regulate the mat to keep the baggy temp always at my setting. Around 90-95 f

The pre-soak definitely speeds things up, especially if you change the water out frequently.  This helps leech any germination inhibitors left by the fruit off of the seeds.  If they are bumming you out, just dig them up, do a pre-soak for a few days, and put them back in.  You should see results within 2-4 weeks.  You won't need sunlight, just heat.

Uh oh....... I hope I didn't fry them! I think I'm going take them out and soak them like @kinzyjr suggested and see what happens. I hope I didn't fry them, because I bought that box of dates specifically to sprout them! :P If I did, though, I'll get my next box from the Mediterranean supermarket instead of Meijer. I also had the thought today that perhaps they had been pasteurized, since I got them at Meijer instead of a more local place. (In the USA, they can pasteurize things and still label them as "raw," which is a whole other soap box, but there was a HUGE thing regarding "raw" almonds a few years back. You have to try and find imported ones now that are truly raw. I hope dates aren't the same!) 

We keep the house at 70 and it's a little drafty sometimes, but the kitchen is often warmer due to the dishwasher and cooking. Do you think keeping them in a bowl on the counter at room temp would be warm enough for the soaking? The last time I did this, my old apartment was perfect greenhouse conditions. All my plants in this new place are unhappy or dead/dying except for my Chicago fig!

@RaychHasDatePalms Dates are relatively resistant to both hot and cold so long as the hot/cold isn't too extreme.  I don't think you fried your seeds unless it went over 140F for a bit.  There have been stories of people forgetting these things in their car on a hot day with the windows up and they still sprouted.  Just to underscore the resiliency of date pits, a 2,000 year old date pit was sprouted: http://www.palmtalk.org/forum/index.php?/topic/1018-methusela-revival-of-ancient-2000-yr-old-palm/

Good luck on it and let us know how it goes.

OMG I am totally about to nerd out on that link, too; I am obsessed with ancient/pre-history. Thanks for encouraging tonight's bunny hole! :P

I soaked the seeds for a few days and just stuck them back to germinate. We will see what happens this time!

Just to update, I’ve had no luck with the seeds so far. I’m going to keep them in the bag, since they don’t take up much room anyway, but I’m also collecting seeds from a box of (much fresher) dates that I picked up at the local Middle Easter store. I wasn’t sure if the first ones had been irradiated or not, but these new ones should do beautifully. I think I’m going to stick them in a window once the weather heats up a little more—it’s still chilly here in west MI.

Thanks! Tips for if the mat has no setting mechanism?

For me I just don’t put them on the mat. I’ll put a black liner tray over top which gives a barrier and also a thermometer inside at least to make sure

I have had these germinate at room tempature and out in the hot sun, pretty quickly for both also. I always soak mine in water (changed daily) for anywhere from one to three days though, fresh or not. They are a fun palm to grow, just watch out for mold, it likes to grow on whatever little residue of the fruit it can find on the seed!

So any seeds germinated?
