GT Herb Focus | Specialised Liquid Fertiliser Australia

Culinary herbs grown in pots and raised beds consistently underperform their outdoor counterparts because container growing limits the mineral reserves available to the plant. GT Herb Focus is formulated to correct this, delivering the complete nutrient profile that drives the rapid leaf production, intense flavour compounds, and essential oil content that makes home-grown herbs worth growing.

What GT Herb Focus Delivers

The nitrogen-led formula in GT Herb Focus supports fast, consistent leaf production across culinary herbs without the excessive vegetative stretch that occurs with high-nitrogen all-purpose fertilisers. Trace element ratios are specifically balanced for flavour compound production — the sulphur, iron, and manganese levels that influence essential oil content in basil, coriander, thyme, and rosemary are all present at the correct concentrations.

The urea-free, chloride-free formula is safe for edible crops at every stage of growth, from seedling through to harvest. Unlike synthetic fertilisers that produce fast growth at the expense of flavour, GT Herb Focus supports both productivity and the aromatic qualities that make fresh herbs worth growing at home.

How to Use

Dilute 5 to 10ml per litre and apply during regular watering. Use weekly during active growth and reduce to fortnightly in slower winter conditions. Suitable for indoor herb gardens, windowsill pots, outdoor raised beds, and hydroponic NFT herb systems.

Suitable For

Basil, coriander, parsley, mint, thyme, rosemary, oregano, chives, and all culinary herbs grown in pots or raised beds.

Frequently Asked Questions

How do I use GT Herb Focus correctly?

Shake GT Herb 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 Herb Focus with all plant types?

GT Herb 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 Herb 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 Herb 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 Herb Focus ship fast within Australia?

Yes — GT Herb 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.
