I wanted lifted beds to fill with yard-amount soil right before I could sow my very first season’s plantings. I procured a number of kits manufactured with untreated wood — they had been affordable and easy to assemble — and packed them with a mix of bagged soil and composted kitchen area scraps.
It only took me a couple of yrs to regret my decision. The facet planks buckled, and those people resting on the floor rotted away. The rich loam inside of started spilling out onto the white pebble pathways all-around the beds, an eyesore and a waste. This spring, I ripped them out and replaced them with a trio of new elevated beds and an herb back garden on wheels, but very first I spoke with 3 gardening specialists and used a lot of time researching my solutions.
Listed here are the five factors they say you ought to take into account when picking out raised-mattress kits.
Products. Kevin Espiritu, founder of Epic Gardening, commonly suggests getting steel elevated beds above these made of wood. “When you do the calculation on longevity of steel as opposed to wooden, steel beats out wooden,” he claims. “And throughout the pandemic, the cost for wood has skyrocketed, so at times wooden is even far more pricey than metal.” He notes that very good steel beds will past additional than a decade with suitable care, which includes guaranteeing the bed does not flood frequently or continually sit in moisture. And line it with geotextile cloth or landscape fabric if you are rising crops necessitating acidic soil, which will corrode the metallic.

Dimensions. Beds ought to be at least a foot tall, states Josh Singer, a neighborhood backyard specialist with the D.C. Section of Parks and Recreation. “Bigger crops, these kinds of as tomatoes and squash, need at minimum that a lot area for their roots to develop,” he suggests, including that you can even dig up a different foot of floor down below the bed to give crops area to develop. To make certain that you can conveniently achieve across the full bed — and that it won’t be so extended that the sides bow out — he advises trying to keep beds two to 4 ft huge and 4 to eight feet prolonged.
Attractiveness. “In urban and suburban parts, you most likely only have a patio or tiny garden, so you are in all probability heading to want to like what you’re seeking at out there,” claims Tim Williams, operations supervisor of Greenstreet Gardens, a landscaping and style and design business. “But if fairly is not a issue for you, do not worry about it. No one is likely to judge you.”
Assembly. “It’s intelligent to have gloves on hand,” Espiritu claims. “I normally assemble kits employing a drill with a screwdriver bit on it — set to a minimal torque, so you’re not more than-screwing the bolt or stripping it out — simply because it is a lot quicker. And have a person with you to support with the create. It’ll just be a lot easier.” Really do not fail to remember to guarantee that your mattress is on even ground, for the reason that a raised bed on a slope will get unbalanced moisture distribution and might leak soil. (Have a stage helpful if you do not truly feel comfortable eyeballing it.)
Cost. Previous, but hardly ever least, look at your spending budget. A metal elevated-mattress package can value several hundred bucks, in addition transport service fees if it is not readily available regionally. The excellent information, nevertheless, is that by this time of year, lots of kits will be on sale or on clearance in the D.C. region. “But never wait as well very long, because they will become unavailable, and it will be far too late to plant most points,” Williams says.
Below are four lifted-mattress kits the authorities recommend.
Vego Garden’s 17-inch six-in-one particular modular steel elevated bed. If you’ve been browsing raised-mattress possibilities on Instagram, you have possibly found these eye-catching beds with rounded corners. Williams is a supporter. “It’s superb how a lot floor spot you can get and the huge soil quantity for deep root programs,” he claims. The 10-piece package with 17-inch-tall sides can be constructed into 6 configurations, equally sq. and rectangular, including 2 by 2 toes and 5 by 3½ feet. It takes about 35 minutes to put jointly. When attaching the panels in this package and the other individuals, test that the tops and bottoms are aligned simply flip the panel if not.

Designed of galvanized steel with an Aluzinc coating, the bed can be built into nine setups, rectangular and square, this kind of as 40 by 24 inches and 66 by 40 inches. It’s 29 inches tall, so you really don’t have to bend more than to attain your plants, Espiritu suggests, “which is great for gardeners who are aged or who have accessibility challenges.” Established aside about 45 minutes to construct and put in it.
Olle’s 17-inch 12-in-1 galvanized lifted mattress. The panels are manufactured of galvanized steel and coated with Aluzinc, designed to reflect the sunshine and keep a constant soil temperature. The 12-piece package of 17-inch-tall panels can be reworked into a dozen configurations, each rectangular and square, which includes 80 by 40 inches and 44 by 24 inches it need to take about 35 minutes to assemble. Singer likes this package for the reason that of its longevity and top. When it will come to filling it, he suggests a blend of 90 p.c topsoil and 10 p.c compost the latter will decompose more than the yr. “Dump a few of bags of compost into the mattress at the get started of each individual year to refresh the natural make any difference,” he suggests. “And since the soil compacts, you actually have to until it very well each individual calendar year.”
Eternally raised beds. “If you want a bed that is not wood but will past a long time and seems to be like wood, this is the way to go,” Espiritu states. Intended to search like they’re crafted with cedar planks, these beds are produced from a composite of recycled wood and plastic. They are readily available in configurations of 3 by 3 feet or 3 by 6 feet, producing them fantastic for scaled-down yard gardens. Be expecting it to take about 15 to 20 minutes to assemble.
