I want to see that during grafting and seeding that I get at least 70 to 80% result.
Cinnamon works for germinating seeds. I haven’t tried it for grafting. It seems to prevent rotting during germination. Some seeds you can nick with finger nail clippers a little bit them place them between damp paper towels for a few days. Fresh seeds work best but even older seeds are worth a try.
You can make a homemade rooting hormone using willow bark.
