I love the look of raised garden beds. I think they look neat and organized, and provide a clear indication of where your garden's visitors should--and more importantly, should not--walk. There are a number of other benefits to using raised beds, though, and few of them are purely aesthetic.
Using raised beds allows you to have good garden soil, regardless of your normal soil condition. Because you fill your raised beds with potting soil and compost, or soil mix for square foot gardens, it doesn't matter whether your soil is rich or poor, or even exists at all (you can put your gardens on raised platforms, concrete driveways, or anywhere you like, though placing them on wood decks isn't recommended).
Raised beds help protect your plants from accidentally being stepped on, since they are clearly delineated and should not be more than 4' (1.2m) wide. Your raised garden should never be wider than you can reach from its edge, so that you never have to step or kneel in it for weeding or harvest. This maintains good drainage in your garden and promotes good root growth because soil stays loose and aerated. The downside of this aspect is that you may need to water more often to make sure your plants stay happy.
Well planned raised gardens can actually hold more plants. When starting fresh, you should not have many weeds, and because the soil is going to be nutrient rich, you can safely plant your flowers or vegetables closer together, allowing them to naturally inhibit weed growth as they grow.
Because your raised beds are narrower than traditional row gardens, maintaining your garden is easier. You can even place your garden beds up on platforms (about hip height) to eliminate kneeling and limit bending to weed your garden. Gardens elevated this way are great for elderly or disabled people because they're easy to access. Just be aware of watering needs when your beds are up off the ground.
Elevating your garden can limit access by pests as well as ease the strain on knees and backs. Certain animals, of course, won't care that your garden is 2 feet above the ground, and will find a way in regardless. Others may not be as willing to get into your veggies that way. Deer, however, will think you've laid out a buffet for them, so you'll want to take other steps to protect your veggies if you have larger pests of this type.
The biggest drawback to this type of garden is the initial expense. You will need lumber (or a kit) for the boxes, and while you can use topsoil in your raised bed, this really defeats the purpose, so it only makes sense to fill it with a more nutritious blend of potting or garden soil and compost. Your initial soil mix will be a bit expensive, and should include a variety of compost sources. You may want to elevate your garden, which will add additional lumber/plywood and block or some other support. After the first season, however, the expense begins to even out, because you'll only need to top it off with an inch or so of compost mix to refresh the nutrients each year and after two to five years you may need to replace parts of your boxes. But you'll be reaping the full benefits of this design in your first season and beyond.
