Whether you’re starting a garden from scratch or expand your existing masterpiece, raised garden beds are a great solution for many garden problems including poor soil quality and drainage, slopes, and accessibility issues.
In case you’re not sure yet, I’ve already outlined the benefits of using raised beds here.
Convinced?! Let’s go!
Raised Beds Can Save a Garden
When I finally switched my main vegetable gardens over to raised beds, my gardens took off like crazy! In my case I had terrible clay soil on a sloped yard so any good soil I had would just wash away. Who knew you could solve life problems with a simple box!
Keep Your Best Soil Where You Need It
Raised beds not only allow you to put your best soil and compost right where you need it, but they keep it there. Over time, as you rotate crops and amend the soil with compost, the entire growing space becomes downright luscious.
Before You Build
Here’s some things to consider before choosing a design for a raised bed.
1. Budget / Longevity
A realistic look at your budget is probably the quickest way to narrow down your options. I used to long for gorgeous stone raised beds until I priced out the cost of one small bed. That was enough to send me to the wood lumber department.
Plain, untreated wood is usually the most affordable option. Naturally rot-resistant choices like cedar are pricier and much longer-lasting. As said, stone can break the bank. Free palettes will require more work (dismantling, cutting, planning) but, if you love the rustic look, the price may be right.

2. Soil and Food Safety
Anything you introduce into your garden becomes part of life in the garden, affecting everything including the wildlife (from microbes to four-legged critters), soil, water, and air. And you.
Always error on the side of caution with garden beds and only use wood (or other materials) that are proven to be ‘food safe’, free of harmful chemicals, agents, or preservatives. For more on choosing safely and sustainably, see How to choose the best wood for raised beds.
The height and width of your raised beds should allow easy access to the entire bed. I don’t like anything wider than 4 feet and 3 feet is even better. I also don’t like to waste wood so I tend to build according to the wood available: 8 foot lengths are used for 4-foot wide beds and 6-foot lengths are used for 3-foot wide beds.
Another important consideration is the space around your raised beds. I once placed several beds fairly closely together and just about lost my mind at planting time when I realized I could not actually kneel down to work because there was nowhere for my legs to go. Save yourself some anguish and plan this out ahead of time. I ended up emptying and moving all the beds.
Most sites recommend a box depth of at least 6″ (six inches or 15 cm). I prefer at least 10 inches of depth (with room to expand as the soil builds up each year). Also, the deeper the bed, the more leg room for root vegetables like carrots that get fussy about these things. Plus, deep beds provide more options for converting beds to cold frames for winter growing.
If your own mobility is an issue, a tall raised bed or a raised bed on legs can be a great solution (see #3 below). Some gardeners find kneeling is painful or impossible so this is a good work around: bring your garden to your best working height.
I solved a space issue at my old home by building a little pond and garden area inside a raised bed. Sometimes you can have your cake and eat it too.
4. Skill Level & Tools Available
A raised bed can be as simple or complex as you like. If you’re building the project yourself, consider your skill level, the tools you have available, and the materials you will be working with. I always like to push myself to learn a little more each time I build something but there is heartbreak when you have some beautiful, expensive pieces of wood and you get the cuts wrong. Measure three times, take a break to think it over, and cut once!
Also, watch out for plans with miter cuts. They look fabulous but they’re not so fun to do if you don’t have a saw with miter cut abilities. If you have the right saw, it’s a beautiful thing.
For years I did not have any power tools (other than an electric drill) and it was not fun trying to do anything beyond basic cuts in thin boards. Now, with the right power tools on hand, I love nothing more than an afternoon spent building something new. My key to happiness is good ear protection. I hate the noise and the ear covers solved this. I also try to time it so I’m only using noisy tools when my neighbours are as well.
If you don’t have a good electric saw, consider getting all the cuts done at the home improvement store where you purchase the wood. They may charge extra, but nice, clean, accurate cuts make a world of difference.
Depending on what you want to grow, consider the amount of sun and drainage the site gets as well as accessibility to water. Can the hose reach or will you need to haul water?
I started building raised beds to combat sloped conditions. Be sure the design and materials you choose can accommodate any challenges like this. Video #6 below provides one example of building on a slope.

6. Style / Aesthetics
And finally, it’s nice if you love how they look. I love gardening because it’s where art, form, and function meet. Nice-looking raised beds can become the focal point of a beautiful garden.
