Raised Garden Beds for Beginners: Three 8-Foot Galvanized Kits That Go Up in an Afternoon

Why a first raised bed should be big, simple and galvanized

A beginner needs a bed that goes together on a Saturday morning, holds enough soil to grow real food and does not rot, warp or need a saw. That is an 8 by 4 foot galvanized steel kit: the panels bolt or clip together with the hardware in the box, the open base sits on lawn or dirt, and the 32 square feet inside grows tomatoes, peppers, beans, lettuce and herbs for a household in one season. The three kits here are the ones a first-time gardener can put up alone, and they differ in height, soil volume, what is in the box and how long the steel will last.

This guide is built from the published specifications of each bed and from recurring owner feedback. We have not run these beds ourselves.

How the three compare

Land Guard 8x4x2: the full-size first bed

Two feet of height is the difference between a bed and a garden. Land Guard puts the planting volume of its 8 by 4 by 2 foot kit at 64 cubic feet, which is deep enough for beans, broccoli and other medium to deep rooted crops without the native soil underneath mattering much, and tall enough that weeding is done standing bent at the hips rather than kneeling. The upgraded coated steel plate is made to sit in sun, rain and snow, reinforced cross bars and fixed stakes keep the long 8 foot sides from bowing once the soil is in, and the open base drains. The cost of the height is soil: 64 cubic feet is a lot of bags, and most beginners fill the bottom third with logs, branches and leaves before the mix goes in.

Kinddeer 8x4x1 two-pack: two beds, no tools

The Kinddeer kit is two 96 by 48 by 11.8 inch beds in one box, and it assembles without extra tools because the screwdriver wrench and gloves are included. The panels are thick galvanized steel plate with an anti-rust coating made to stay in contact with soil, the base is open so roots go down into the ground and water goes out, and Kinddeer backs it for three years. Each bed takes about 31 cubic feet of soil, so a pair is about the same fill as the single Land Guard with twice the growing area. Twelve inches is enough for lettuce, peppers, bush beans, carrots and herbs on decent ground; tomatoes will root down through the open base.

Vego Garden 17-inch 9-in-1: the bed that lasts twenty years

Vego Garden makes the bed most experienced gardeners end up buying, and it is a sound first bed too. The 9-in-1 kit builds one of nine layouts, the longest an 8 by 2 foot bed 17 inches tall, from panels of VZ 2.0 steel, a zinc, magnesium and aluminum coating under AkzoNobel paint that Vego rates for a 20-plus year life. The oval shape has no sharp corners and heavy rubber edging covers the panel tops, which matters with children and bare arms. Assembly is tightening fasteners, with no construction knowledge required per Vego. As an 8 by 2 it holds about 23 cubic feet; the trade is a narrower bed at a higher price, with the comfort that it will not need replacing.

Working out the soil you need

Multiply length by width by height, all in feet, to get cubic feet. An 8 by 4 by 1 foot bed is 32 cubic feet; at 2 feet tall it is 64; an 8 by 2 at 17 inches is 8 times 2 times 1.42, about 23. Bagged raised bed mix commonly comes in 1.5 and 2 cubic foot bags, so a 1 foot bed takes roughly 16 to 21 bags and a 2 foot bed twice that, which is why bulk delivery by the cubic yard (27 cubic feet) is cheaper past about 30 cubic feet. For a tall bed, fill the bottom with untreated logs, branches, leaves and grass clippings, water it down, and top with 10 to 12 inches of mix. Place the bed on level ground in six or more hours of sun before filling it, because once full it does not move.

Which one should you buy

Buy the Land Guard 8x4x2 for a single full-size, full-depth bed that grows anything. Buy the Kinddeer two-pack for two tool-free beds and the most growing area for the money. Buy the Vego Garden 9-in-1 for the safest edges and a bed that outlasts the rest.
