Neutrog Seamungus Green 20kg – Premium Organic-Based Soil & Plant Vitaliser
Neutrog Seamungus Green is a high-performance, organic-based soil conditioner and fertiliser designed to revitalize "tired" gardens and provide plants with a resilient foundation for growth. This 20kg professional-grade pack combines the benefits of seaweed, fish, humic acid, and composted poultry manure into a stable, pelletised form. Seamungus Green acts as a biological "kick-start," populating the soil with beneficial microbes while delivering a wide array of naturally occurring growth stimulants and essential trace elements. It is particularly effective at building plant resilience against environmental stresses such as heat, drought, and frost. By improving soil structure and moisture retention, Seamungus Green ensures that plants have consistent access to the nutrients they need to thrive in the challenging Australian climate.
Best For: Reinvigorating soil health and boosting the environmental resilience of all garden types, from large-scale landscapes to productive orchards and lawn areas.
Key Features
- Multi-Source Organic Blend: Harnesses the combined power of seaweed and fish to deliver essential amino acids and natural growth hormones directly to the root zone.
- Climate Resilience: Strengthens plant cellular structure, helping gardens withstand extreme weather conditions, including summer heatwaves and winter frosts.
- Soil Health Restoration: High organic matter and humic acid content improve soil structure, nutrient retention, and the activity of beneficial microbes and earthworms.
- Year-Round Application: A gentle, slow-release formula that is safe for use in every season, providing a steady baseline of nutrition without the risk of burning.
- All-Garden Safety: Certified organic-based and safe for use on all plants, including Australian natives, succulents, vegetables, and established turf.

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)
✔ Direct truck delivery (available in Victoria)
Important Notes:
- Shipping costs vary by location and method
- Because of the forklift requirement, delivery to the nearest depot is the default option and will be the method used unless you contact us to request otherwise.
Business Delivery:
- Business delivery is available for commercial customers only
- If you select business delivery and your products are bulky, it is your responsibility to ensure you have appropriate equipment (including forklifts) to unload products from the delivery truck
- If you select business delivery and you are not a business, you risk your product not being delivered and may incur additional fees to retrieve your order
- Business delivery customers must provide a valid business address and contact information
- Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment
Let us know your preference, and we'll arrange the best solution for you!
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.
