Landscape fabric, also known as weed barrier or garden fabric, is a material used in gardening and landscaping to control weed growth and manage soil conditions. Typically made from synthetic materials like polypropylene or natural fibres such as jute and coir, it comes in rolls and is laid on garden beds, pathways, or under decorative elements.
Its primary function is to act as a physical barrier, inhibiting weed emergence while allowing water and nutrients to penetrate the soil. Whether you're working on residential gardens, commercial landscaping projects, or erosion control applications, selecting the right landscape fabric determines the success of your project.
Constructed by weaving fibres together, this type allows water and air to pass through small holes, making it suitable for areas where both weed control and soil hydration are important. Woven fabrics are typically stronger and more durable than other options, particularly when made from polypropylene.
These materials resist tearing and can withstand foot traffic in pathways and under mulched garden beds. For smaller garden beds and pathways, this 0.91m wide woven mat provides excellent coverage while remaining manageable to install in tight spaces.
Made from bonded materials, non-woven fabric is less permeable and is often used under rocks or gravel to prevent weed growth and stabilise soil. This type works particularly well as a separation layer between different soil types or between soil and decorative aggregates.
Non-woven geotextiles offer excellent filtration properties while maintaining soil stability. They're particularly useful in drainage applications and as underlayment for hardscaping projects where water needs to flow through but soil particles must remain in place.
This type features pre-cut holes, offering a balance between weed prevention and water permeability, ideal for gardens requiring regular watering. The perforations allow for better water infiltration in clay-heavy soils where drainage is a concern.
Some perforated fabrics come with grid patterns that help with plant spacing and layout during installation. This makes them particularly useful for vegetable gardens and formal plantings where consistent spacing matters.
Biodegradable landscape fabrics made from jute, coir, and other natural fibres provide temporary weed suppression while eventually decomposing into the soil. These materials work exceptionally well for establishing new plantings or controlling erosion until vegetation takes hold.
Natural fibres add organic matter to the soil as they break down, improving soil structure over time. For establishing native plantings or revegetation projects, these 600mm jute mats are ideal because they suppress weeds during the critical establishment phase and naturally decompose within 18-24 months.
By blocking sunlight, landscape fabric reduces the germination and growth of weeds, decreasing the need for chemical herbicides. The fabric creates a dark, inhospitable environment beneath the surface where weed seeds cannot photosynthesize.
This method of weed control is particularly effective in commercial plantings, around established trees and shrubs, and in ornamental garden beds. When covering large commercial areas or farm boundaries, this 5m wide heavy-duty roll provides efficient coverage with fewer seams, reducing installation time and potential weak points where weeds might emerge.
Landscape fabric helps stabilise soil on slopes or areas prone to erosion by holding soil particles in place. This is particularly important on construction sites, along waterways, and on sloped garden beds where rainfall can wash away topsoil.
The fabric reduces the impact of raindrops on bare soil and slows water movement across the surface. For steep embankments and creek restoration projects, these 200mm diameter coir logs work brilliantly as they provide immediate erosion control while allowing vegetation to establish through the natural fibres.
Proper installation determines whether landscape fabric succeeds or becomes a maintenance headache. Start by clearing the area completely of existing weeds, rocks, and debris that could puncture the fabric.
Level the surface as much as possible to prevent low spots where water might pool. When laying fabric, overlap edges by at least 150-200mm to prevent weeds from emerging through gaps.
Secure the fabric with landscape staples or pins every 300-500mm along edges and seams. Cut X-shaped slits for existing plants rather than large holes, and fold the fabric back against the plant stem to minimise exposed soil.
Always cover landscape fabric with at least 75-100mm of mulch or aggregate. This protects the fabric from UV degradation, adds aesthetic appeal, and provides additional weed suppression.
The fabric weight, measured in grams per square metre (GSM), indicates durability and intended use. Light fabrics (70-90 GSM) suit temporary applications and annual garden beds, while heavy fabrics (100+ GSM) handle high-traffic areas and long-term installations.
Consider the permeability requirements of your specific site. Clay soils need highly permeable fabrics to prevent waterlogging, while sandy soils tolerate less permeable options.
Match fabric type to project duration. Use biodegradable options for temporary erosion control or revegetation projects where you want the fabric to disappear within a few years.
Select synthetic fabrics for permanent installations under decking, around building foundations, or in commercial landscapes where longevity matters. For medium-width applications like garden bed edging and residential pathways, this 1.83m woven poly mat offers a practical balance between coverage and handling ease for DIY installers.
While landscape fabric offers several benefits, it's essential to install it correctly and choose the appropriate type for your specific project. Over time, organic matter can accumulate on top of the fabric, allowing weeds to grow above it.
Regular maintenance and the addition of mulch can enhance its effectiveness and longevity. Replenish mulch annually to maintain the recommended 75-100mm depth and remove any weeds that appear before they establish deep roots.
Inspect fabric edges periodically, especially after heavy rain or strong winds. Repin any lifted sections and add additional overlap if gaps have appeared.
Expect synthetic landscape fabrics to last 10-20 years when properly installed and maintained, while natural fibre options typically break down within 1-3 years depending on soil conditions and climate. UV exposure is the primary enemy of synthetic fabrics, which is why keeping them covered with mulch or aggregate is critical.
