It’s pretty much set it and forget it for the life cycle of the plant. Of course it depends on the plant and the size of the bucket. I’ve successfully grown lettuce, bok choy, basil and mint so far in 5 gallon buckets and a fluorescent grow light panel. I have 3 plants growing per bucket.

With the back yard, it’s just a large back yard and the wife used a sod kicker to remove grass all along the fence and we put in raised beds. We have about 8 raised beds, each about 4x4, that e grow in and then we also have trellises around the yard that we grow things like squash, cakes, beans, etc on, directly out of the ground
