How To Use Mulch & Weed Mats and Rolls

The Yard Crew

Guaranteed 100% Pure New Zealand Wool

We make Wool Mulch & Weed Mat Rolls from 100% New Zealand wool. This creates a completely natural, renewable product, which is safe to install, safe to live with and safe for the environment.

Convenient & Easy to Use

Wool Mulch & Weed Mat Rolls are simple to use, providing all the advantages of a layer of mulch, while also eliminating weed growth. Our mats are flexible, protect against erosion, and are available in sizes to suit every project.

Promotes Plant Growth

New Zealand wool is full of essential nutrients that promote plant growth, including nitrogen, phosphorus and potassium. Wool Mulch & Weed Mat Rolls slowly break down over time, releasing nutrients into the soil and acting as a fertiliser.

Water & Temperature Regulating

Wool stores up to 33% of its weight in water, and slowly releases water once the surrounding environment drops below 65% relative humidity. This means our mats act as a water buffer, keeping plants at the right moisture level. As wool absorbs water, it releases a small amount of heat, helping to regulate the soil temperature and provide ideal growing conditions.

Fully Biodegradable

Wool Mulch & Weed Mat Rolls are strong enough to do the job without any need for synthetic glues or strengthening materials. Once your wool mat has biodegraded, the only thing left behind is healthy plants and enriched soil. For ultimate sustainability, secure your Wool Mulch & Weed Mat Rolls with our fully biodegradable pegs, which break down at the same rate as the mat.

Naturally Pest Resistant

Wool might feel soft to the touch, but wool fibres have very fine scales, and tiny barbs - which means that slugs and snails go out of their way to avoid them! The composition of our mats also means that birds can’t scrape the mat away from your garden.

How to use your Wool.Life products

Step one:

Clear the area you plan to plant in by removing any existing weeds.

Step two: (optional, rolls only)

If you are using one of our Mulch & Weed Rolls cut your roll to size using sharp scissors or a knife. Then cut a hole where you would like your plant positioned.

Step three:

If you are using a roll place your plants inside the cut holes. If you are using one of our Mulch & Weed Mats position the slit around the stem of the planting, then secure the mats or rolls with pegs.

Step four:

Water your plants and watch them grow confident that your Mulch and weed matting will provide pest resistance, frost protection, moisture retention and suppress weeds from growing and will mulch down to provide valuable nutrients for plant growth.

Frequently Asked Questions

General & How-To

What is wool mulch?

Wool.Life mulch is made from both post-industrial recycled and non-recycled New Zealand wool textiles, pressed into mats or rolls. It acts as a natural, biodegradable alternative to plastic or synthetic mulches.

How do you use wool mulch in the garden?

Simply lay Wool.Life mulch around plants or over garden beds, leaving space around the stem. Water it in to settle the fibres, and it will naturally suppress weeds, hold moisture, and break down over time. Follow our preparation guide to ensure you prepare the ground correctly.

How long does it take for wool mulch to decompose?

In most New Zealand conditions, wool mulch lasts 12–24 months before breaking down fully, depending on rainfall, soil biology, and exposure.

Can you use raw wool for mulch?

Raw wool can be used, but as it is loose it can blow away, allow more weeds to grow through and is messier to handle. Wool.Life mulch is processed into easy to handle rolls and mats, making it cleaner, easier to handle, and more consistent.

Is wool mulch good for all plants?

Yes, Wool.Life mulch can be used with natives, ornamentals, fruit trees, and vegetables. It’s especially useful for water-sensitive plants as it locks in soil moisture.

Benefits & Pros

What are the benefits of using wool mulch?

Wool mulch suppresses weeds, retains moisture, enriches soil as it biodegrades, regulates temperature, and reduces plastic waste in gardens.

Is wool mulch a good fertiliser?

While not a fertiliser on its own, Wool.Life mulch slowly releases nitrogen and other nutrients as it decomposes, boosting soil health naturally.

Does wool mulch stop weeds from growing?

Yes, Wool.Life mulch blocks light from reaching weed seeds, significantly reducing weed growth while still allowing air and water to reach the soil.

Does wool mulch help with moisture retention?

Absolutely. Wool fibres absorb and release water, helping soils stay moist for longer and reducing the need for frequent watering.

Does wool mulch deter slugs and snails?

Yes, the coarse wool fibres create a barrier that many slugs and snails avoid crossing, reducing damage to tender seedlings.

Does wool mulch help regulate soil temperature?

Yes. Wool acts as a natural insulator, keeping soils cooler in summer and warmer in winter, protecting plant roots from stress.

Is wool mulch good for sandy soil?

Yes, it’s especially helpful in sandy soils because it reduces water loss, prevents nutrient leaching, and improves organic matter over time.

Comparisons & Cons

Is wool mulch better than bark mulch?

Wool mulch lasts longer, suppresses weeds more effectively, and adds nutrients as it decomposes. Bark mulch is decorative, but it breaks down more quickly and doesn’t regulate soil as efficiently.

Wool mulch vs. straw mulch: which is better?

Straw is cheap and easy to spread but breaks down quickly and can introduce weed seeds. Wool mulch is denser, longer-lasting, and offers better weed suppression and moisture control.

What are the disadvantages of using wool mulch?

The main drawback is cost—it’s more expensive than bark or straw upfront. However, its longer life, nutrient return, and environmental benefits make it excellent long-term value.

Does wool mulch attract pests?

No, Wool.Life mulch doesn’t attract rodents or insects. In fact, its texture can deter slugs and snails.

Is wool mulch more expensive than other types of mulch?

Yes, initially. But Wool.Life mulch lasts longer and provides more benefits than cheaper options, so the lifetime cost is competitive.

Practical & Environmental

Where can I buy wool mulch in NZ?

You can order Wool.Life mulch online at woollife.co.nz with nationwide delivery. Bulk and wholesale orders are also available for landscapers and councils.

Is wool mulch organic?

Yes. Wool is a natural, biodegradable material. Our mulch is made from 100% NZ wool without synthetic coatings.

Is wool mulch safe for vegetables?

Yes. Wool.Life mulch is safe for use in vegetable gardens, helping improve soil health while protecting crops.

Can you put wool mulch in a compost bin?

Yes, wool mulch can be composted once it has broken down in the garden. It contributes nitrogen and organic matter to your compost system.
