Frequently Asked Questions about Durable GreenBed™ raised garden bed kits.

Mineralized Composite Raised Bed!

Durable Greenbed’s patented mineralized wood chip composite panels are  strong, non-toxic, durable and attractive.  We haven’t found a better solution.  Have you?

Cedar vs Composite for Raised Beds?

Wood rots, with an average life where the soil touches it of 5 years.  Metal cuts and rusts.  Treated lumber  is toxic and leeches chemicals.  Plastic tends to warp and bend with a load of soil next to it. Composite boards like Trex aren’t meant for this kind of use, and require supports to prevent warping.  So What is the best material for raised beds?   

Metal vs Wood for Raised Beds?

Modern looking metal raised beds are trending in urban settings now, but homeowners perhaps are unaware of the danger that the sharp, exposed edges in most beds post to children and adults.  One fall, and it will be very clear why metal raised beds are a hazard in most situations.  In addition, non galvanized metal will rust out relatively quickly when in contact with soil, and galvanized metal contains zinc, and it is unclear how much is contained in soil that is adjacent to galvanized metal.

Best Lumber for Raised Beds?

All lumber is temporary for raised garden beds.  Cedar and Redwood are naturally the most rot resistant untreated wood found in the US, but most wood lasts 4-6 years, and will rot quickly when in contact with warm, moist soil, rich in microbes, which is what is best for growing your garden.  You might be tempted to use Pressure treated lumber for your raised beds, but…

Pressure Treated Wood or Railroad Ties for Raised Beds?

 You never want to use pressure treated or chemically treated lumber, NEVER USE Railroad ties  for raised garden beds, as the treated lumber contains chemicals that are hazardous to human health and can leach into the soil and your food.  

The Durable GreenBeds will survive whatever winter throws at them. The panels passed the ASTM C-666 300 cycle freeze-thaw test without cracking and breaking down. However, to protect your plants from the cold, we suggest adding a cloche to your GreenBed! Here is a link to plans for a 4×8 season-extending mini greenhouse.

It has been shown that GreenBed practically eliminates the invasion of slugs into the garden! The rough walls of GreenBed repel the slugs from crawling up the sides and into the garden.  This is a welcome benefit for gardeners everywhere who have battled these voracious feeders.

The 4 x 8 kits take between 45 and 90 minutes to assemble.  The 1’ and 2’ high Durable GreenBeds are easily assembled under 60 minutes of your time.  The tiered beds will take approximately 90 minutes.  All of the holes are pre-drilled. All that you need is a level place to put the Durable GreenBed, a hammer, a tape measure,  a cordless drill with a ¼” nut driver and Phillips head and a socket wrench with a ¼” socket.  Assembly is easy and instructions are clear.

Wood rots, plastic boards are, well, plastic and they don’t stand up to UV, railroad ties are out due to creosote, cement blocks are heavy and unsightly, and pressure treated wood is suspect for vegetable growing.  The best materials for garden beds are attractive, durable, and non-toxic.  Most of the available planter beds are not that attractive-simply a wood or plastic box. Durable GreenBeds are healthy, durable, and beautiful. One of the best features is the breath-ability of our panels.  This brings oxygen to the root zone which greatly benefits healthy plant development.

The main component of the GreenBed is a unique material called Faswall, a woodchip/Portland cement composite material invented in Europe and used to build high-performance, sustainable buildings. GreenBed wallpanels are made from this same remarkable rot-free and non-toxic material. Other materials used for gardening beds such as wooden panels, plastic boards, cement blocks, railroad ties, and pressure-treated wood have either longevity and/or toxicity issues. In addition to the GreenBed panels the kits include aluminum brackets, and a cedar wood trim kit with a bio-based non-toxic penetrating oil finish.
