**Key takeaways:** - Woven ground cover is **PP tape fabric** that blocks weeds, drains water and stands up to pots, carts and foot traffic. ;; **Greenhouse and nursery floors** typically use about 100 g/m² (3 oz/yd²), black or white, with **guide lines** for spacing. ;; Coverage: **one acre = 4,047 m²**; add 5–10% for overlaps and edges. ;; Heavy tarps can **smother weeds in 3–6 weeks** before planting (occultation). ;; The same fabric works as yard ground cover, on rocky soil and as a tent ground cloth.

Woven ground cover is a woven polypropylene fabric laid on the ground to stop weeds, keep surfaces clean and let water drain away. Greenhouses, container nurseries and vegetable farms use it because it lasts many seasons, tolerates pots, carts and foot traffic, and cuts herbicide and hand-weeding costs. A typical grower specification is black or white PP woven ground cover around 100 g/m² (about 3 oz/yd²), UV-stabilized, with guide lines woven in at fixed spacing.

This article focuses on commercial growing operations: where ground cover pays off, how to size orders, and how to install it on large areas.

## What is woven ground cover?

PP woven ground cover is made by extruding polypropylene film, slitting it into narrow tapes, stretching them for strength, and weaving them on looms into a flat fabric. The small gaps between tapes let water and air pass; the dense tapes block light. Carbon black or white pigment and UV stabilizer are added at the extrusion stage.

Compared with other ground cover material:

| Material | Drainage | Traffic resistance | Service life | Typical use |
|---|---|---|---|---|
| Woven PP ground cover | Good | High | Many seasons (UV-stabilized) | Nursery and greenhouse floors, rows, orchards |
| Non-woven spunbond | Very good | Low | 1–2 seasons | Light beds, frost cloth (a different, thinner product) |
| PE mulch film | None (unless perforated) | Low | 1 season | Annual vegetable beds |
| Gravel | Excellent | High | Permanent | Fixed areas; heavy, costly to install |
| Concrete | Needs drains | Very high | Permanent | Fixed benches and loading areas |

For a general overview of fabric types and weights, see the [heavy duty landscape fabric guide](/blog/heavy-duty-landscape-fabric-guide/), and for GSM by crop see [weed control fabric GSM and UV](/blog/weed-control-fabric-gsm-uv-guide/).

## Greenhouse ground cover

On greenhouse floors and under benches, ground cover does more than stop weeds:

- **Hygiene.** It keeps soil out of the growing area and reduces habitat for pests such as fungus gnats, shore flies and thrips pupae that develop in bare soil and algae.
- **Drainage.** Irrigation and runoff pass through instead of pooling around pots.
- **Clean working surface** for carts and staff.
- **Light reflection.** White greenhouse ground cover reflects light back up into the canopy, which is valued for low-light seasons and for crops grown on the floor. Our [PP or PE Material White Large Weed Mat Ground Cover](https://www.egpbags.com/products/woven-fabric-weed-mat/pp-or-pe-material-white-large-weed-mat-ground-cover-for-agriculture/) is supplied for this purpose.

Black fabric absorbs heat and is the default where extra light is not needed. Some growers use black in aisles and white under crops.

**Tip:** lay ground cover over a lightly sloped (about 1–2%), compacted base of sand or fine gravel so water does not collect under pots.

## Nursery ground cover fabric for container yards

Outdoor container nurseries are the largest users of woven ground cover. Requirements:

- **Strength** to support pots and the wheels of carts and small tractors
- **Root-control:** woven fabric stops roots growing from drainage holes into the soil, which would otherwise tear when pots are lifted
- **UV stability** for years of exposure without a mulch layer
- **Guide lines** to set out beds, so pots can be spaced quickly and consistently

Guide lines are commonly woven at 6, 12 or 25 cm spacing (about 2.4, 4.7 or 9.8 in) in a contrasting color. Ask for the spacing that matches your pot sizes.

Nursery beds are often crowned slightly, so water runs to drainage ditches at the sides, and ground cover is laid across the full width of the bed.

## Agricultural fabric for field rows and orchards

In open fields, woven agricultural fabric is laid along rows rather than across whole fields:

- **Strawberries, raspberries and blueberries:** a weed suppressing ground cover along the row, with planting holes
- **Orchards and vineyards:** strips 1–1.5 m (3–5 ft) wide along tree rows, keeping the alley in grass
- **Perennial herbs and cut flowers:** multi-year rows with burned planting holes
- **Tree nurseries:** rows of field-grown trees planted through fabric

Our [UV Stabilized PP Weed Mat Offset Printing Extended](https://www.egpbags.com/products/woven-fabric-weed-mat/uv-stabilized-pp-weed-mat-offset-printing-extended-lifespan-for/) is used in multi-year rows where the fabric stays exposed.

### Installation at scale

On farms, rolls are typically laid by tractor with a mulch-laying attachment that shapes the bed, lays the fabric and buries both edges in soil furrows. Burying the edges 4–6 in (10–15 cm) deep holds the fabric better than pins alone. In nurseries and greenhouses, wide rolls are pulled by hand and pinned; see our [step-by-step guide to laying landscape fabric](/blog/how-to-lay-landscape-fabric/) for pin spacing.

## How much ground cover do you need?

**Area to cover (m²) = length (m) × width (m)**, then add 5–10% for overlaps, edge burial and waste.

**Rolls needed = area with allowance ÷ (roll width × roll length)**

### Worked example: container yard

A nursery bed of 100 m × 30 m (328 × 98 ft):

- Area: 100 × 30 = 3,000 m²
- Plus 8% for overlaps: 3,240 m²
- Using 4.2 m × 100 m rolls (420 m² each): 3,240 ÷ 420 = 7.7, so **8 rolls**
- Fabric weight at 100 g/m²: 3,240 × 0.1 kg = **324 kg** (about 714 lb)

### Worked example: one acre

One acre is 4,047 m² (43,560 ft²). With 8% allowance you need about 4,370 m² of fabric, roughly 437 kg at 100 g/m².

### Coverage per roll

| Roll size | Area per roll | Weight per roll at 100 g/m² |
|---|---|---|
| 1.0 m × 100 m (3.3 × 328 ft) | 100 m² (1,076 ft²) | 10 kg (22 lb) |
| 2.0 m × 100 m | 200 m² (2,153 ft²) | 20 kg (44 lb) |
| 3.2 m × 100 m | 320 m² (3,444 ft²) | 32 kg (71 lb) |
| 4.2 m × 100 m | 420 m² (4,521 ft²) | 42 kg (93 lb) |
| 5.25 m × 100 m | 525 m² (5,651 ft²) | 52.5 kg (116 lb) |

Wider rolls mean fewer seams but heavier handling. Many nurseries use the widest roll two people can safely move.

## Using a tarp for weeds (occultation)

Before planting, many vegetable and flower growers smother weeds with a heavy, opaque tarp left on the soil for several weeks. This is called occultation.

- Lay the tarp over moist, prepared soil and weigh the edges down with sandbags or soil.
- In warm weather, **3–6 weeks** usually kills emerging annual weeds and leaves residue that is easy to rake off. Cooler weather needs longer.
- Weeds germinate in the warm, moist conditions under the tarp and then die without light, which reduces the seed bank near the surface.
- Perennial weeds with deep roots may need repeated treatments.

Silage tarps (thick black-and-white PE film) and coated woven PP tarps are both used. Woven ground cover can also be used, but because it is permeable some light-tolerant weeds may survive; an opaque coated fabric works better for occultation.

## Other uses for weed control ground cover

### Yard ground cover and landscape ground cover

Around sheds, storage yards, fences, and under decks, a heavy woven fabric topped with gravel gives low-maintenance landscape ground cover. For gravel areas see [landscape fabric under gravel, pavers and rock](/blog/landscape-fabric-under-gravel-pavers-rock/).

### Ground cover for rocky soil

On rocky ground, sharp stones puncture light fabric from below. Rake off loose stones, add a thin layer of sand or fines where possible, and use a heavier woven grade of 130 g/m² or more. Plastic stakes often hold better than wire staples in stony soil.

### Industrial sites

Equipment yards, mines and storage areas use heavier black fabric to stop vegetation and dust. Our [Commercial Grade PP Weed for Fabric Moisture Proof Black](https://www.egpbags.com/products/woven-fabric-weed-mat/commercial-grade-pp-weed-for-fabric-moisture-proof-black-for-mining/) is made for these conditions.

### Camping ground cover and tent ground cloth

Woven PP is also a practical tent ground cloth (footprint). It is tough, light, cheap and easy to clean. Two tips:

- Cut the ground cloth 2 in (5 cm) **smaller** than the tent floor on all sides, so rain running off the fly does not collect on the cloth and flow under the tent.
- A coated (waterproof) woven tarp works better than permeable weed fabric for camping ground cover, since you want to block ground moisture.

## Ground cover to prevent weeds: choosing the specification

| Use | Color | Weight | Extras |
|---|---|---|---|
| Greenhouse floors | White or black | 100 g/m² | Guide lines; white for light reflection |
| Container nursery | Black | 100–130 g/m² | Guide lines; UV-stabilized for long exposure |
| Strawberry and vegetable rows | Black | 80–100 g/m² | Pre-burned holes |
| Orchard strips | Black or green | 100–130 g/m² | UV-stabilized |
| Industrial yards | Black | 130 g/m² and up | Reinforced or high-load grade |

## Frequently asked questions

### What is the best ground cover for a greenhouse floor?
Woven polypropylene ground cover of around 100 g/m², laid over a lightly sloped, compacted base. Choose white to reflect light into the crop or black for maximum durability and weed control.

### Is woven ground cover permeable?
Yes. Water and air pass through the gaps between the woven tapes, so pots and greenhouse floors drain well while light is blocked.

### How long does nursery ground cover fabric last?
UV-stabilized woven fabric commonly lasts several years in full sun, depending on the stabilizer level, climate and traffic. Ask your supplier what UV level the fabric is designed for.

### How long should I leave a tarp to kill weeds?
In warm weather, 3–6 weeks is typical for annual weeds. In cool weather, or for perennial weeds, leave it longer or repeat.

### Can I use weed fabric as a tent ground cloth?
Yes, it is durable and cheap, but a coated waterproof woven tarp is better because it blocks ground moisture. Cut it slightly smaller than the tent floor.
