Water will penetrate the seed coat and cause the embryos inside to plump up. Don’t soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.
What stops seeds from germinating?
Seeds produce a hormone called abscisic acid, or ABA, that prevents germination. When environmental factors such as temperature are not optimal for seed germination, ABA levels are high, which causes production of higher levels of a protein called ABI5.
