I saw a video of someone growing mushrooms from burying another mushroom in dirt. However, most other videos show only show that you can grow mushrooms from spawn or spores from a company. Can you actually just bury a mushroom and grow your own? If not is there any way to pull the spore yourself and grow mushrooms? I want to grow mushrooms year after year without buying new spawn every time it runs out.
Depending on what you mean by "mushroom", some are not difficult to propagate , many are difficult to propagate. They have specific environmental needs . I have started cominus comatus -shaggy manes -a few places ; they are tolerant of location. I have just tossed the mature mushrooms onto lawns. I have read that shitake grow fairly well on oak wood ( cut branches and trunks). The common ( in US grocery stores) agaricus compestry is grown on artificial manure in caves or dark warehouses.
