Hello /out/! I've decided to become the next Johnny Appleseed, planting apple trees wherever I go hiking.

I've already got a few clearings in some state game lands near me picked out, but I've never really planted trees before. Would it be better to plant a bunch of germinated seeds close together, or would it be best to grow saplings at home and take them with me to plant? If the latter, how would you recommend that I carry them?
