Our columnist Kevin Lee Jacobs shows us how to build a raised bed garden and explains why it's easy to grow vegetables, flowers, and herbs in these convenient elevated beds. We asked our Facebook fans what they would plant in a raised bed, join the conversation and share your ideas too!
Red Bed Gardening
If the idea of growing a year's supply of healthy, organic vegetables and herbs appeals to you, but the thought of digging through compacted, rocky soil does not, consider growing your crops as I do: in raised beds. You'd be amazed at how many benefits there are to gardening "on higher ground,"and how easily beds can be constructed.

What You'll Need
You can build a raised bed from almost any material you like, as long as it is sturdy and does not contain harmful chemicals. Do not use pressure-treated lumber(including railroad ties)because it contains toxins that can leach into the soil. Bricks, cements blocks, and untreated lumber are all suitable for framing.

Even cheap pine boards can be used to frame a bed. Pine,however,is not rot-resistant,so you'll have to replace it after four years or so. The boards will last longer if you first paint them with raw, not boiled, linseed oil. I used untreated 1-by-10 inch pine for the beds in my herb garden. After one season the wood turned from boring beige to graceful gray. I paved the paths between beds with pea gravel, and then enclosed the entire garden with wire mesh attached to pressure-treated posts.
For my kitchen garden, I built eight 4-by-8 foot beds from inexpensive, rough-hewn hemlock. Hemlock, like cedar and redwood (these last two are pricey) is naturally rot-resistant. The boards of these beds are 12-inches high and 2-inches thick. Running perpendicular to the hemlock-enclosed beds are four 2-by-8 foot beds framed with 1-by-10 inch pine. Paths here are paved with shredded wood chips, and the garden is protected from woodchucks, rabbits, and deer by wire-mesh fencing.
How to Build It
As for building a timber-framed bed, no carpentry job could be easier. Simply join the corners together with galvanized nails or screws. I used 1 1/2-inch nails for my thin pine-framed beds and 4-inch screws for my thicker hemlock models. Although corner posts are commonly used for raised beds, I have not found them necessary.
Before filling a frame with soil, it is imperative to line the bottom of the bed with either corrugated cardboard or several thicknesses of newspaper. This material will smother any weeds or grass that would otherwise grow up through the raised bed and that would impede your perfect planting plan.

Flowers in Raised Beds
Of course, flowers love raised beds as much as vegetables do. I always plant zinnias in th long central beds of my kitchen garden; they attract the bees and butterflies necessary for pollinating my crops and provide beautiful bouquets for indoor enjoyment.

Perfect Soil!
Raised bed gardens mean that you get to garden in perfect soil. By "perfect," I mean soil which is fertile, well-draining, and free of rocks and weeds. My own veggies flourish in equal parts top soil, composted manure, and sand. These components were mixed and delivered by a local farm. I've known other gardeners who fill their beds with packaged mixtures obtained from the garden center or hardware store.
To insure ongoing fertility from year to year, and to avoid the need to purchase additional soil to refill the beds as settling occurs, I top my beds off each fall with sharedded leaves. As the leaves decompose over winter, they add vital nutrients to the soil, and improve its water-retention.

Soil in a raised bed does not become compacted. Why? Because it is never walked upon. Unencumbered by hard clumps of soil or rocks, root vegetables like carrots and parsnips grow straight and long; beets and turnips grow into hte beautiful globes depicted on their seed packets.
Easy Harvesting
If you suffer from a bad back, you will appreciate being able to plant and harvest your vegetables without bending deeply. In fact, if you build your beds high enough, you won't have to bend at all. If you limit your beds to 3 to 4 feet in width, you will not have to reach excessively, either.
