This guide covers installing the weed-control net: ground preparation, measuring and positioning, fixing with metal staples, creating openings for plants, and covering with gravel, mulch or substrate. Follow these steps to prevent weed growth for years without resorting to herbicides, in a garden, vegetable plot or landscaped area.
Product specifications
The weed-control net is a black UV-treated polypropylene fabric, permeable to water and air but opaque to light. Available in three widths according to the size of the area to be covered, with a standard length of 100 m per roll. The choice of width determines the number of joins and the amount of fixings per m².

Step-by-step use
Correct installation determines how long the net lasts. Three factors are critical: prior soil preparation, overlap between rolls and sufficient fixing.
Prepare the ground
Remove existing weeds (by hand, with a rotary tiller or with a systemic herbicide applied 7-10 days beforehand). Remove stones and sharp sticks that could pierce the net. Level the surface with a rake. If there is a risk of weeds with very deep roots (thistles, perennial weeds), apply herbicide before covering.
Measure, cut and position
Measure the area and choose the width that minimises joins (1 m for narrow linear flower beds; 2 m for medium areas; 4 m for large surfaces such as under decorative gravel or extensive crops). Cut with scissors or a utility knife. Position the roll at the end of the area and unroll it lengthwise. Overlap 10-15 cm (4-6 in) between adjacent rolls.
1 m variant: ideal for linear flower beds under hedges or along borders. For wide beds it means many joins. 2 m variant: a balance for medium residential gardens. 4 m variant: only for large surfaces; on small beds it forces trimming and wastes material.
Fix with metal staples
Place garden metal staples every 30-40 cm (12-16 in) along the edges and joins, and every 80×80 cm (1 staple per 0.6 m²) in the interior of the roll. On soft ground, fit a staple stop to prevent it from sinking too far. In windy areas, reinforce to 60×60 cm (1 staple per 0.4 m²).
Create openings for plants
If the net covers a bed with existing plants or where you will plant, make a cross-shaped (or circular) cut over each plant just the size of the collar: pass the plant through the opening and close the net back around it. This way the plant grows freely and the net blocks weeds.
Cover with gravel, mulch or substrate
To protect it from UV and improve its appearance, cover the net with a 5-8 cm (2-3 in) layer of decorative gravel, pine bark, organic mulch or substrate. The covering multiplies the net's service life by 3-4 and improves water retention for the crop.
When installing under decorative gravel, define the path of rainwater before you start: if the ground is completely flat, consider adding perimeter drainage or spot outlets. The net lets water through, but a bed flooded for days is a separate problem: the gravel gets dirty and mosquitoes appear. A minimum slope of 1-2 % towards an outlet point solves the problem.
Do not use weed-control net under sown lawn or turf. The net blocks light, preventing the development of the very lawn you want to establish. Weed-control net is applied where you do NOT want anything to grow (flower beds, gravel, around trees), not where you do want vegetation. For a lawn area, prepare the ground and sow directly onto soil without net.
Complementary products
The weed-control net forms a system with the fixing and, frequently, with an aesthetic covering:
The garden metal staple is the standard fixing to hold the net to the ground. The garden metal staple stop prevents the staple from sinking too far into soft ground. The agricultural ground plastic is the alternative for professional vegetable growing: it blocks weeds like the net but also waterproofs the soil and raises the temperature to speed up cultivation.
Maintenance and care
The weed-control net is long-lasting when installed correctly:
- Storing the roll: in a dry place, not exposed to prolonged sunlight. Once the roll is open, re-roll the leftover part carefully so as not to form creases that are difficult to remove later.
- Service life with covering: under gravel or mulch, 8-12 years without losing functionality. Under direct exposed sun, 2-3 years.
- Periodic inspection: every year, remove a small section of gravel in strategic areas and check the condition of the net. Local tears are repaired by overlapping new net and re-fixing with staples.
- Weeds growing on top of the net: over time soil accumulates on the covering and seedlings appear growing on top. This is not a fault of the net: pull them out by hand when they appear, since their roots do not penetrate the net and come out easily.
- Disposal at end of life: polypropylene is recyclable. When you renew your garden, remove the old net and send it to a recycling centre rather than to general waste.
Frequently asked questions
Can I use the net with drip irrigation?
Yes, it is the preferred combination for vegetable plots and professional beds. Run the drip lines OVER the net, fixing them with garden staples every 1-2 m. The water reaches the crop through the openings made for each plant. Some systems run the drip line under the net for greater protection: it works but makes inspection and repair of the line harder.
Does it let enough water through?
Yes, the woven polypropylene net has a typical permeability of 50-100 litres/m²/minute, more than any reasonable irrigation and much more than the heaviest rain. The only drainage problem would come from poor preparation of the ground under the net, not from the net itself.
What do I do if a very persistent weed comes through the openings?
The openings you made for plants are also escape routes for weeds that germinate very close by. Apply a spot contact herbicide with an applicator only in those areas, avoiding splashing the main plant. If the weed is a perennial with rhizomes (Cynodon, sedge), pull it out until you remove the entire rhizome or it will have a regrowth cycle.
