Find a lonely place on public land near an earthen drainage ditch (they are full of run-off fertilizer from local lawns) move down the slope of the ditch about half way and dig down till you see obvious moister. Place your fully started seedling(s) in the hole(s) and cover the roots with good potting soil lightly packed, early to mid April (depending on temp).
Go away for two weeks, then return to observe (walk the dog) and add, or not, some properly mixed liquid fertilizer designed for tomato plants around the stalk. Hopefully on a rainy day.
Leave them alone. Once every two weeks or so check on them but not obviously, fertilize as you like. When I went to pick mine up in early Oct. I couldn't find them, I could smell them but I couldn't see them. As I looked around I was suddenly shocked and afraid to see 8-9ft plants thriving and fully ready for harvest. Save the dried stalks and shake to make hash oil.
