I found some seeds for a Dictyosperma Album that was on the swale in my neighborhood. I took some brown seeds from the floor around the tree and some green and brown ones from the tree itself. I assume its better to use the brown ones right? But should I use the older, wrinkled ones that I found on the floor? Or the newer, cleaner ones that I picked off the tree? Am I supposed to soak them in water for 3 days before planting? Should I plant them in a pot to begin with? Or directly in the ground? How will I know if they "germinate"? Any other tips?
