Ultimate Black

If you want your garden to instantly look like it was styled by a professional landscaper, Peats Ultimate Black is your secret weapon. Manufactured by Peats Soil—a premier, multi-generational South Australian organics company—this premium woodchip mulch is designed to deliver a striking, modern aesthetic while providing a heavy-duty protective blanket for your soil.

Crafted from high-quality, long-lasting wood chips, Peats Ultimate Black is treated with a specialized, 100% environmentally friendly, non-toxic dye. The result is a rich, deep-black finish that won’t harm your plants, pets, or local wildlife, providing the ultimate contemporary backdrop that makes the green foliage and vibrant colors of your garden pop.

Key Features & Benefits

• Stunning High-Contrast Aesthetics: The deep, uniform black color provides an ultra-modern, clean finish that completely transforms the look of residential garden beds and commercial streetscapes alike.

• Eco-Friendly & Non-Toxic Dye: Formulated using premium, long-lasting colorants that lock onto the wood chips. It is entirely safe for the soil, soil microbes, earthworms, and family pets.

• Excellent Moisture Retention: Acts as a highly effective barrier against the harsh Australian sun. By dramatically cutting down evaporation, it keeps plant roots cool and slashes your watering bills.

  • Natural Weed Suppression: Applied at the right depth, it blocks sunlight from reaching dormant weed seeds, stopping them in their tracks and saving you hours of weeding.

  • Wind & Wash Resistant: The chunky, interconnected nature of the wood chips ensures the mulch stays exactly where you put it, resisting displacement from heavy rain or leaf blowers.

  Best Used For

• Modern & Architectural Gardens: Perfect for minimalist, native, or contemporary garden designs where clean lines and sharp color contrasts are key.

• Commercial Landscapes: Highly popular for storefronts, council gardens, and high-visibility corporate landscapes due to its long-lasting color vibrancy.

• Feature Garden Beds & Planters: Gives a premium, manicured finish to high-visibility front gardens, driveway borders, and large courtyard pots.

Application Tips for Best Results

• Recommended Depth: For optimal weed suppression and moisture control, apply Peats Ultimate Black at a uniform depth of 75mm.

• Leave Room to Breathe: Always leave a small gap between the mulch and the base of plant stems or tree trunks to prevent moisture buildup and collar rot.

• Refresh Cycle: Because it is a durable woodchip blend, it decomposes slowly, providing long-term coverage. A light top-up every 12 to 18 months is all it takes to keep that rich, deep-black color looking brand new.
