Plants grow outside in soil
naturally, it's what they do
There are extra problems outside (deer, pigs (both kinds lol), other mammals) but once the plants get big enough they have lots of pluses. Where you are is important to the soil and what you need to do to make it primo for you weed. First you need to know if it's alkaline, neutral, or acidic and work from there. If you are in middle america...say east of dallas, your soil is probably OK. If you are where it's Alkaline you need to address that.
