If you’re looking to start a vegetable garden and not sure where to plant it, this guide discusses the pros and cons of raised versus in-ground beds to help you find the best fit for your garden
The 2020 chapter about the revival of the American victory garden was one most of us didn’t see coming. As we’ve all hunkered down to ride out the pandemic, the idea of homegrown food has gone from romantic to downright pragmatic. While the catalyst for the rise in home gardening is undoubtedly different now from the 1940s, questions from new gardeners remain consistent.
What can I plant in my climate? Where can I find unique seeds? What type of irrigation is best?
One thing that has changed is that you can find answers to most of these queries in a matter of seconds: a whole wealth of knowledge is available at your fingertips.
As edible gardening experts, we’re no stranger to these questions. One of the most common queries we receive, and one of the most popular resources on our website, is where to plant your new garden. It’s a pretty literal question: where, as in, in the ground? Or in raised beds?
California Farm and Garden (formerly Urban Plantations) has essentially made a whole business out of answering this question for the last 12 years. The importance of adequate design and planning before installation is key to the success of each garden.
We’re here to shed some light on this age-old inquiry: should you plant your new vegetable and herb garden directly in the ground or in raised beds? Both options have their pros and cons of course, and the answer will vary based on your personal vision and goals for the garden, the available space, your budget, your health, and more.
Without further ado, the CA Farm and Garden guide for Southern California’s new home gardeners.
Let’s start at the very beginning, what exactly is a raised bed? Simply put, a raised bed is any type of prefabricated container that can hold soil. These are often made using wood, concrete, metal, or stonework. The variety of mediums available give gardeners a customizable and unique way to display their proud work and offers flexible options to compliment your garden’s aesthetic. As opposed to a flat layer of plants in the ground, raised beds can be installed with different heights, sizes, colors, and shapes for a multidimensional experience.
More importantly, raised beds give gardeners an excellent chance to reap immediate and long-lasting edible success. Fill raised beds with new, organic soil teeming with beneficial microbial life, and mix in a custom blend of amendments to establish your plants in a healthy environment from the get-go. You won’t be wasting time wondering if the soil is too sandy, too overworked, or too rootbound, and you won’t have to put together a multi-year plan to regenerate the soil. Raised beds give you full control over the soil environment your veggies and herbs will be living in.
They also offer the perfect setting for water-conscious irrigation, like pressurized drip or micro sprayers. Although raised beds typically don’t have bottoms, they can use water more efficiently than in-ground beds. The new, healthy soil installed in the beds on a (presumably) flat, level surface promotes hydration and prevents unnecessary runoff.
An added bonus of using drip and micro-irrigation in a raised bed is weed prevention. By only irrigating specific areas, you’re saving water and making it tough for weeds to sprout.
Raised beds better support a wider variety of critter control options as well. From lining the bottom of the beds to keep gophers out, to building removable cages on top to keep even the most motivated ground squirrel at bay, critter control should play a significant role in your planning.
Don’t forget about fido—building taller raised beds or installing low fencing in the beds can keep your pooch from having more fun in the garden than you!
Finally, there’s the matter of convenience. Have a bad back? Install a taller raised bed (or a bed on legs) so you don’t have to bend over. Thinking about moving in the next few years? With proper planning, you can even take a raised bed garden with you.
If initial startup costs are a concern, you might want to think twice about raised beds. Whether you’re building them yourself, purchasing prefabricated beds, or hiring a licensed contractor like California Farm and Garden, raised beds can range in price from a few hundred dollars to thousands to establish.
In addition to the costs of different materials to build raised beds, it’s also important to consider what kind of process was used to create the materials themselves. Being exposed to the elements for years on end can result in chemicals and other toxins from your raised bed leaching into the soil, causing a variety of unforeseen, possibly harmful consequences to your soil, plants, and maybe even family. Common sources of toxins include pressure-treated wood, or coating the inside of your bed with some kind of sealant. It’s important to consider the source for all aspects of your new garden, from your plants and seeds to the bed they call home.
Another possible downside? Depending on your available space, installing raised beds could actually reduce your plantable square footage. Factoring in the width of the wood, pathways for accessibility, proximity to walls, and more can limit your raised bed and space options.
They’re also not suitable for all fruits and vegetables. Depending on the size and depth of your raised beds, they’re often not ideal for plants like fruit trees or fruiting vines. Creating shallow raised beds can hinder root growth and options to plant root crops too.
Lastly, it’s important to remember that many common raised bed materials have lifespans. Weighing the values of aesthetics, cost, space, and lifespan can all play a role in deciding if a raised bed is the right choice for your new garden.
Costs associated with starting a new home garden directly in the ground can be significantly lower than those of raised beds. Often, some infrastructure is already in place (like irrigation), and if you’re especially lucky, you might discover rich, fertile soil perfect for growing crops already existing on your property.Planting in-ground can offer a more natural aesthetic, especially if you elect to plant something like a food forest as opposed to neat rows of vegetables. Because you can take advantage of existing odd shapes and lines around your property, chances are planting in-ground will provide more plantable square feet than raised beds. You also have the opportunity to plant larger edibles like fruit trees who enjoy the root space!
If your property doesn’t naturally have rich soil, consider planting in-ground to regenerate poor soil. Cultivating organic fertilizers and amendments can turn “dirt” into healthy, loamy soil. The fungi, bacteria, insects, worms, and more will all appreciate a healthy and vibrant hyperlocal ecosystem.
Depending on your vision and budget, in-ground beds can certainly provide a realistic way to get your garden started quickly and beautifully.
Installing your fruits and vegetables in-ground can pose a number of challenges, especially for newer gardeners. If you’ve drawn the short straw and discover the soil around your home is too sandy, has too much clay, or maybe it’s fill dirt from recent construction, it can take years to regenerate health. While you might find your garden still produces, seeing unhealthy plants and low production numbers can certainly be disheartening.
Dealing with unwelcome gleaners can become especially challenging when relying on in-ground beds. Gophers can sneak in from below; possums, skunks, and rabbits can climb or hop over short fencing; and birds can swoop down from above. While each neighborhood has a diverse and unique ecosystem, chances are you’ll have to deal with critters like these in Southern California. Many of the solutions for protecting your in-ground beds won’t be all-encompassing, and they tend to be less aesthetically pleasing.
Speaking of aesthetics, it’s important to remember as a new gardener that you do get to make a choice based on wants for the actual appearance of your garden. Planting in-ground can result in a look that becomes a bit too farm-y for some, while others don’t like the oft-chaotic look of a food forest.
Finally, it’s important to touch on convenience again. Gardening in-ground can be physically challenging and usually takes some time on your hands and knees to get each project completed. Critter protection options for in-ground beds can introduce additional obstacles too.
Whether weighing options for a 21st-century victory garden or simply planning for a future where your outdoor space doubles as the grocery store, landing on the right way to plant a garden can be tricky. Do your research, dream big about your goals, and get your hands dirty. Both in-ground and raised beds may have their pros and cons, but at California Farm and Garden, we tend to think any edible garden lands in the pro column.
