From sheep to soil - giving wool a second life in your garden.
Wool Garden Mulch is a 100% natural, New Zealand-made mulch built to be a genuine garden all-rounder. Made from a blend of shredded wool and sheep manure, it works as a soil conditioner when dug through the ground, a natural filler for your compost, and a top layer that suppresses weeds, deters slugs and snails, and helps your soil hold onto moisture — all without chemicals. Suitable for veggie gardens, flowers, shrubs and trees. 1kg covers approximately 1 square metre.
What it does
Wool fibres hold up to three times their weight in water, so you're watering less often. As the mulch breaks down over 6–12 months, it releases nitrogen and organic matter back into the soil, working like a slow-release fertiliser. Dug directly into the soil, it also improves structure, encourages beneficial microbes, and increases worm numbers — worms being one of the better indicators of a healthy, productive garden. The coarse texture of the fibres creates a natural barrier that slugs and snails won't cross, making it a pet-safe alternative to chemical pest control.
What you can use it on
Works across all garden types: tomatoes, courgettes, silverbeet, lettuce, herbs, strawberries, flowers, fruit trees and shrubs. Suits vegetable gardens, raised beds, garden pots, and flower beds. Safe to use year-round in the New Zealand climate — insulates roots in winter, keeps soil cool in summer.
How to apply
Two ways to use it: spread a 3–5cm layer on top of the soil around plants (keeping a small gap around stems), or dig it directly into the bed to boost soil health and feed your worm population. Either way, water in after applying to help the fibres settle in and start working. Reapply or top up after 6–8 months.
Frequently asked questions
Does wool mulch keep slugs and snails away?
Yes — the coarse wool fibres are uncomfortable for soft-bodied pests to cross, acting as a physical barrier without poison or chemicals.
How long does wool mulch last?
Approximately 6–12 months, depending on weather, after which it's broken down fully into your soil as organic matter.
Is wool mulch safe for vegetables and edible gardens?
Yes — it's 100% natural and chemical-free, safe for use around edibles, kids and pets. (Wash food before eating and hands after gardening, as usual.)
How much does 2.5kg cover?
Approximately 2–3 square metres at a 3–5cm depth.
Can I dig wool mulch into the soil instead of laying it on top?
Yes — digging it in is a great way to improve soil structure, add organic matter, and encourage worm activity for long-term garden health.
