GT Native Focus | Specialised Liquid Fertiliser Australia

Australian native plants are uniquely sensitive to phosphorus. Most standard fertilisers contain phosphorus at concentrations that cause phosphorus toxicity in Grevilleas, Banksias, Proteas, and other members of the Proteaceae family — a slow-progressing condition that kills roots, produces chlorotic foliage, and ultimately kills the plant. GT Native Focus is formulated with ultra-low phosphorus specifically to prevent this.

What GT Native Focus Delivers

The ultra-low phosphorus profile in GT Native Focus delivers the complete mineral nutrition that Australian native plants need — nitrogen for growth, potassium for root function and stress tolerance, and a full trace element profile — without the phosphorus excess that damages phosphorus-sensitive species. The formula is safe for repeated use in both container and garden-grown natives where conventional fertilisers have previously caused damage.

Australian native plants in cultivation frequently display slow growth, yellowing, and decline that growers attribute to poor soil or pests when the actual cause is phosphorus toxicity from standard garden fertilisers. Switching to GT Native Focus as the exclusive fertiliser input often resolves these symptoms within one to two growing seasons and restores vigour to plants that have been in decline.

How to Use

Dilute 5ml per litre and apply fortnightly during the active growing season (spring through early autumn). Reduce to monthly during winter. Do not combine with any other fertiliser containing phosphorus. Compatible with all Australian native species in containers and garden beds including Grevilleas, Banksias, Waratahs, and Hakeas.

Suitable For

Grevilleas, Banksias, Proteas, Waratahs, Hakeas, Leucadendrons, and all phosphorus-sensitive Australian native plants.

Frequently Asked Questions

How do I use GT Native Focus correctly?

Shake GT Native Focus well before use. Add the recommended dose to water and stir well before applying. For potted plants and hydroponic systems, apply at every watering during the active growing season. Reduce frequency during winter dormancy. Always water plants with plain water every few waterings to prevent nutrient salt build-up in the growing medium.

Can I use GT Native Focus with all plant types?

GT Native Focus is specifically formulated for the plant type indicated in the name. Using a product formulated for one plant type on another is generally fine but results may not be as optimised. The key difference is the NPK ratio and trace element balance — each Focus formula is tailored to the specific nutritional requirements of that plant group.

What is the difference between GT Native Focus and a general all-purpose fertiliser?

General fertilisers are designed to be acceptable for a broad range of plants without being optimised for any particular group. GT Native Focus is formulated with the exact macro and micronutrient ratios that produce optimal results for its specific plant type. This means better growth rates, stronger root systems, more vibrant foliage, and higher yields compared to general-purpose alternatives.

Does GT Native Focus ship fast within Australia?

Yes — GT Native Focus ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
