Problems with 12 year old seed germination

Try soaking the seeds in a diluted seaweed extract.. . The natural growth hormones (auxins, cytokinins, and gibberellins) present in seaweed can help stimulate cell division and root development inside the embryo. I usually also add some sort of oxygen source for older seeds with this method. An air stone or something along those lines should be fine.

For every year that's passed of improperly stored seeds, this process gets much harder.

Another pricey option would be sending them off for embryo rescue...


Pōmaikaʻi iā ʻoe (Good luck)!
