Why would a raised garden bed require a soil liner?
A soil liner for your BEDurVEG raised hardwood garden bed or any garden bed or wicking bed has multiple purposes to support your growing.
It is an important addition if you plan on placing your garden bed on a hard surface, to stop any leaching of the soil onto that hard surface, particularly when your beds are exposed to heavy rain.
But, there are many other benefits to using a soil liner regardless of whether you plan on placing your garden beds on a hard surface or a softer surface such as grass or subsoil.
Most importantly, the soil liner will stop any invasive roots from established trees or vegetation around the garden beds from entering the growing medium in your garden beds and competing for nutrients.
Likewise, weeds will not be able to invade your garden bed and rob your soil of fertility, thus protecting the growing medium for your specialized plants – vegetable or other.
Additionally, the soil liner separates the endemic soil which could contain contaminants, from your ideal growing medium, allowing you to grow safely anywhere.
Finally, the liner will protect the water proofing membrane on the inside of our PREMIUM hardwood garden bed range. This is a soft and flexible layer that is durable but can be damaged. By protecting the timber with the membrane, then protecting the membrane with the liner, you will fully optimize the longevity of your investment!
