Pest Management is probably the one subject no one wants to think about. Still weeds and bugs are an issue. Depending on where you are, and what you are growing, Pests can be construed as including birds, squirrels and deer as well. If deer are a problem, fencing may be an important part of the solution. It also may be a matter deciding to grow something else. Regardless, bugs and weeds are going to be an issue. In deciding what to do, you need to consider what you are willing to put up with, as there are upsides and downsides to everything.
