There is a definite set of levels when it comes to food production in the backyard. I feel like the average person does a little container gardening or may a single plot for tomatoes in the summer. The next level is adding herbs and maybe some expansion. Beyond that you start getting serious about your soil and amending it. You might move to building elaborate trellises or something to that effect after that. Once your garden expansion begins you will find yourself looking at a new option. The possibility of trees is a serious step forward. Suddenly you are creating a small orchard and not just a raised bed garden.
This article is about starting fruit trees from seed. Most of the time you buy these guys when they are just little babies. I bought my first trees in little bags of dirt. They are all grown up now but its a step I never regret taking.
