Here we start our topic of discussion about Should I Put Landscape Fabric Under Raised Bed? Raised garden beds are a fantastic concept. Raised garden beds come in various sizes, shapes, and designs. There is no one correct material or method for making them. This essay will address one of the most often requested questions. Should you line your raised garden bed with weed cloth or liners?
A raised vegetable bed does not require weed cloth or weed liners, but they can assist keep soil in and weeds out. While you may not require one, it is rarely a bad idea to have one. Let’s talk about the benefits and drawbacks of weed textiles in raised beds, various liners, and options for keeping weeds out of your raised garden bed.
Should I Put Landscape Fabric Under Raised Bed?
Relying on your budget and gardening plans, you can line the bottoms of your raised garden beds using wide-mesh hardware cloth, stainless steel mesh, landscape fabric, burlap sack, or newspaper/cardboard. Details on each can be found below.
Hardware cloth with a large mesh Earthworms can still pass through this material, which keeps weeds and burrowing animals out. These are the gardeners of nature, aerating and nourishing the soil for your plants’ benefit.
During the building procedure, staple the fabric to the bottom of the garden bed frame. Once installed, it should last for many years. Gopher or rat mesh made of stainless steel. This long-lasting substance is designed to keep burrowing creatures out. Pin it in position to keep it from shifting around.
Fabric for the landscape if you have a weed problem in your yard, landscape fabric might help keep undesirable plant growth out of your raised garden beds. Sack made of burlap Have you got an old potato bag lying around? This material works well as a weed barrier when stapled to the bottom of a garden bed frame.
Cardboard or newspaper these simple, low-cost materials can keep weeds out of your plant beds. Put them out on the ground before constructing your garden beds on top of them. Alternatively, insert sheets of newspaper or cardboard near the top of your planters for the added moisture-retention advantage of mulch.
Avoid using plastic to line your garden beds since it hinders drainage and may drown your plants’ roots. Consider putting a mix of metal mesh and fabric or hardware cloth and cardboard to receive both benefits at once if you have a weed and pest problem.
Should I Put Weed Barrier Under Raised Bed?
The decision to put a weed barrier under a raised bed is not a strict necessity, but it can be beneficial in certain circumstances. Weed barriers, such as landscape fabric, can effectively keep unwanted plant growth at bay, especially if you have a weed problem in your yard. They are typically made from materials like polypropylene or polyester.
However, it’s worth noting that weed barriers are not the only option. Alternatives like newspaper, cardboard, or leaves can also serve as effective barriers. These materials are great for smothering weeds and grass, and they eventually break down into the soil, contributing to its nutrient content.
A raised garden bed liner can also insulate the soil, prevent weeds, and keep pests out, while allowing water to drain away. If you’re using pressure-treated wood or railroad ties for your raised bed, a liner can prevent harmful chemicals from leaching into the soil.
Remember, the positioning of your raised bed is crucial for optimizing sunlight exposure. Ensure your location isn’t shaded by shrubs or trees before construction.
In conclusion, while it’s not strictly necessary to put a weed barrier under a raised bed, it can help in weed management and soil preservation. The choice of material—be it a commercial weed barrier, cardboard, newspaper, or leaves—depends on your specific needs and circumstances. To Make it more easy for you to decide I have shared a study below:
A Study: Use of fabric and compost mulches for vegetable production in a low tillage, permanent bed system: effects on crop yield and labor.
The research conducted by R. Feldman, C. Holmes, and T. Blomgren in 2000 presents an intriguing proposition that polypropylene landscape fabric could serve as a viable substitute to the conventional polyethylene film in the context of permanent vegetable cultivation beds.
In their study, the team explored the efficacy of employing polypropylene landscape fabric and compost as mulching alternatives to bare soil for the cultivation of red cabbage and watermelon. The polypropylene landscape fabric shares similar characteristics with the widely used polyethylene film in commercial vegetable farming.
However, its superior durability allows for multi-year usage, potentially mitigating the environmental impact caused by the single-season usage of polyethylene film.
Conversely, compost used as mulch contributes to soil enrichment while offering benefits such as weed control and water retention.
Over a span of three years, the team measured the yields of red cabbage and watermelon in plots treated with either 10 cm of compost, landscape fabric, or no mulch at all. They also recorded the labor involved in crop production and weed control.
The results showed that the yield of cabbage over the three years was highest with compost, followed by no mulch, and then fabric. For melon, the yield order was compost, fabric, and then no mulch. In terms of labor, the fabric-treated plots required the most effort initially but saw a significant reduction after the first year as the fabric was left in place.
The labor for unmulched cabbage plots and both unmulched and compost-mulched melon plots increased due to weeding and transplanting.
In conclusion, compost provided the highest crop yields with a moderate labor investment and significantly increased the nutrient levels in the underlying soil. The study suggests that polypropylene landscape fabric could be a promising alternative to the traditional polyethylene film for permanent vegetable cultivation beds.
To sum up all about Should I Put Landscape Fabric Under Raised Bed? It is critical to use liners in raised garden beds. Liners keep weeds and pests out of your crops while retaining moisture by trapping water vapor that would otherwise evaporate. There are several distinct types of liners, each with its benefits.
A sturdy plastic liner should be placed in a raised garden bed to prevent water from reaching the wood used to construct the bed. Other options for keeping weeds out of your garden include roasting the soil, using fresh soil mix, planting cover crops, etc.
