Brunnings Coir Potting Mix 65L - Professional High-Yield Sustainable Substrate

Brunnings Coir Potting Mix is a premium, professional-grade growing medium specifically engineered to provide superior moisture retention and aeration for a wide range of gardening applications. This high-yield "Mega" block is designed for maximum efficiency, expanding to a substantial 65L of high-quality potting substrate when rehydrated. Naturally derived from renewable coconut husks, it offers an eco-friendly and sustainable alternative to traditional peat-based mixes. The unique honeycomb structure of the coir fibers allows it to absorb and retain up to eight times its weight in water while maintaining excellent air porosity, ensuring that roots remain hydrated without becoming waterlogged. Naturally sterile and pH neutral, Brunnings Coir Potting Mix provides a clean and stable foundation that helps protect vulnerable plants from soil-borne pathogens. Whether you are filling large outdoor planters, creating custom potting blends, or improving garden soil texture, this versatile coir substrate delivers the consistent moisture and high-oxygen environment required for vigorous and healthy plant growth.

Best For: Maximizing water retention in large containers, providing a sterile foundation for high-volume seed raising, and improving soil structure in garden beds.

Oversized Item Delivery Options

Since oversized items require special handling, we may need to provide a custom freight quote for your order and will contact you with an updated shipping rate.

Available options include:

✔ Delivery to your closest depot for pickup - default method
✔ Direct delivery - requires forklift on site
✔ Direct delivery with tailgate lift truck (extra fees apply)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)

Important Note on Availability & Shipping

Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.

Lead Times:

• In-Stock Items: Usually ready for dispatch the same day.
• Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.

While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.

Biosecurity & Interstate Shipping Restrictions

Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:

• Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
• Seeds cannot be shipped to Western Australia (WA).

Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
