What materials are suitable for the backing of a modular metal raised garden bed?

If you plan to grow herbs and vegetables for food, make sure you are not using treated wood. This type of material can contain toxic chemicals that can seep into the soil and into the plants you eat. Avoid extra chemicals on modular metal raised garden beds by choosing untreated wood. Some untreated wood species can also provide additional benefits. For example, untreated cedar is naturally resistant to insects and rot, making it a fairly low-maintenance option.

Lining the bottom of a raised metal garden bed with a stiff cloth or wire mesh will help keep pests such as gophers or moles out of the interior of your garden bed. The network cable also helps with drainage of the garden bed. If you plan to use them in your vegetable, fruit or herb garden, avoid materials that may not have a food-safe coating to prevent any toxins from leaching into the soil.

Newspaper or cardboard If you're looking for an eco-friendly and inexpensive metal raised lining for the bottom of your garden bed, try some old uncoated newspaper or cardboard. These options also act as a barrier to noxious weeds and provide insulation. However, these materials also allow deeply rooted plants to continue to grow and extend underground. Cardboard and newspaper are also excellent sources of nutrients because they are considered "brown" or carbon-based substances that break down over time.

Many people use plastic sheets or tarps as linings to add protection and insulation to their modular metal raised garden beds. One disadvantage of plastic is that it may not drain properly if used on the bottom of a garden bed. This can lead to standing water and buildup, leading to problems like root rot, and it's best to use plastic as a liner inside a modular metal raised garden bed.

5. Landscape cloth and landscape cloth are ideal choices for preventing weeds from growing and reducing soil erosion. Many landscape fabrics are designed to let water and air flow through, but prevent weeds from growing in the fabric. Landscape fabrics provide good ventilation and help plants thrive.

After choosing the perfect location for your modular metal raised garden bed, line the bottom with the backing material of your choice. If you're using mesh wire or landscape fabric, use landscape or garden nails to hold it in place. Make sure the material is suitable for the walls of the garden bed. If you're using landscape fabric on the bottom and sides, create a tight weed barrier by folding the excess material over the inside walls. Once the lining is set, just add soil and plants. Lining is a great way to get the most out of a modular metal raised garden bed. Not only can you protect the soil from extreme temperature changes, but other threats as well.
