I had read notmarthas post about how to start daylilies in water and peroxide and decided if it worked that well for daylilies that maybe it would help some of the other seeds that are harder to get started. http://davesgarden.com/t/414635/notmartha
I am now using it for everything that I want to soak and am really impressed with the results.
I wish I could give you better information about length of times and which seeds work best, but I am still experimenting with both of those.
What I can tell you is that I have had some really great results.
Moonflowers, 4 o'clock, and morning glories all sprouted roots while they were soaking.
I have had great germination after the soak in the peroxide, distilled water mix.
I really wish that I had kept some data on it, so I could give you better information, but it was one of those "lets try this ideas" that worked out much better than I had any idea that it would.
Larger seeds and things with really hard outer shells I was leaving in the mix for about 3 days, some longer if the seeds were not swelling at all.
I have no idea what it does, but I figured if it could actually root and allow leaves on the daylily seeds that it must be good stuff!!!
I did keep track of some wisteria seeds that I soaked and I left them in the mixture for 3 days and then put in seed starter. I had 100% germination in less than 2 weeks and they are all ready about 4 inches high. I just have no idea if that is good or bad having never started them from seed before.
