I'm new at gardening, but I'm interested in capturing seeds to trees/bushes/plants that I like and trying to grow them. So, after doing some initial research, I have collected some seeds to a Crepe Myrtle and a couple evergreen trees, placed them in a bag, put them in my freezer for 21 days (simulating a winter). This is where I currently stand. The germinating process follows, and from my reading, I came across information that warns of harmful bacteria or insects in the soil used to plant the seeds. It recommended boiling the soil to protect the seed from disease. Can anyone give me more information on this? Or, is this something I should skip? If so, what type of soil should I use to plant?
Thanks!
