Raised garden beds are lovely to look at, practical to use, and do not require as much water and potting mix as traditional in-ground garden beds. There are several suitable materials to consider when constructing raised garden beds because of their durability, cost, and ease of assembly or construction. Raised garden beds can be built from polypropylene plastic, wood, metal, stone, concrete, brick, and aluminum. Other materials such as discarded tires or railroad ties can be used but aren’t recommended because both tires and railroad ties can leach toxins into the soil and the garden vegetables we grow.
When selecting a suitable material to use for constructing your garden bed, you must consider a few things, such as cost, durability, and the potential toxicity of the material you have in mind. While some materials are sturdy and cost-effective, the toxins they leach into the soil and the food you grow can be harmful to you and your family’s long-term health.
A popular material, wood is most frequently used for raised gardening beds. It is essential to consider the quality of the wood as not all wood is suited to long-term outdoor use. The weather and the elements will eventually take their toll on all wood regardless of quality. You can extend the life of your wooden planting beds by pre-coating the wood in moisture repelling treatments or life-extending oils.
Galvanized steel is a material that is sturdy and rust-resistant. While galvanized steel is sturdy, it is important to remember that it will still rust if used in coastal areas where salt and sea air can corrode metal over time. Consider choosing steel coated in a protective powder coat for added longevity. Note that galvanized steel is a heat conductor and may retain and hold on to heat and elevate the internal soil temperature.
In terms of durability, a bed constructed of stone or brick will last a lifetime and require minimal maintenance other than occasional repairs. Concrete planters are long-lasting but also require maintenance and upkeep. Stone and brick materials require less care and maintenance but are often heavy and costly to obtain and use.
Aluminum is sturdy, lightweight, and rust-resistant. However, using aluminum is not recommended. Aluminum can leach into the soil and vegetables over time, especially when outdoors and exposed to the elements. Water and sun exposure cause oxidation which looks like a white, powdery coating on the surface of exposed aluminum. This oxidation can leach into the soil lowering soil pH levels and making the soil acidic. Low soil pH can stunt plant growth, especially in plants that dislike acidic soil and prefer alkaline soil like broccoli, cabbage, cauliflower, and carrots. Aluminum is also a heat conductor, so beware of rising soil temperatures on hotter days.
Polypropylene (PP) is an affordable, sturdy, weather-resistant, and lightweight thermoplastic polymer plastic that can last for ten years even when exposed to heat, sunlight, or left outdoors. Manufacturing polypropylene requires a smaller carbon footprint and has the lowest carbon dioxide emissions of any manufactured plastic. PP also requires fewer natural resources for production, generates fewer waste products during manufacturing, and is widely recyclable.

Once assembled, the planter bed, which comes with optional wheels for maneuverability, is easy and convenient to move around. The planter beds are outfitted with safety heads, and a trellis can be attached to the safety heads to support climbing plants.
Raised beds are advantageous because they require less soil, water, and maintenance. Plants grow better in raised beds and require less maintenance in general. The soil in raised beds stays looser and more aerated because the ground is less compacted as the earth isn’t trod upon frequently. Because of the natural insulation raised beds provide, planting earlier in the spring and continuing into late autumn is possible. In the spring, a raised garden bed encourages the soil to dry out and drain faster so you can begin planting earlier. Yearly refreshing soil mix is recommended, but you’ll find that raised beds suffer less erosion and washout than in-ground garden beds. Elevated beds also make controlling garden pests easier. Woodchucks and rabbits are less likely to infiltrate an enclosed and elevated garden bed, and crawling insects, snails, and slugs still have to find access to the beds by scaling the raised planter walls.
Use our raised garden beds to create planting zones, landscape your garden, or use them to define a space or area in a way that discourages children and pets from entering. Raised garden beds are also easy to protect growing plants during harsh weather because they are easier to cover with a protective tarp and insulate against unwanted elements.
