GT Rose Focus | Specialised Liquid Fertiliser Australia

Roses are among the most fertiliser-responsive plants in cultivation and among the most commonly underfed. A consistent, complete nutrient program produces vigorous canes, abundant flowers, and strong disease resistance. GT Rose Focus is a single-part liquid fertiliser formulated specifically for the nutritional demands of roses across the full growing season.

What GT Rose Focus Delivers

The balanced NPK profile in GT Rose Focus supports both vegetative growth and flower production through the season, with potassium levels elevated to drive the flower quality and colour intensity that roses are grown for. All 12 essential minerals are included, with iron and manganese at concentrations that support deep green foliage and the active chlorophyll production that underpins vigorous, disease-resistant rose growth.

The urea-free, chloride-free formula is safe for container-grown and garden bed roses throughout the growing season. GT Rose Focus is pH-buffered for Australian tap water and requires no adjustment in most conditions, making it a practical choice for rose growers who want consistent results without the complexity of multi-product feeding programs.

How to Use

Dilute 5 to 10ml per litre and apply weekly during the active growing season from the first signs of new growth in spring through to late autumn. Reduce to fortnightly during slower periods. Compatible with pot-grown roses, garden bed specimens, climbing roses, and standard tree roses.

Suitable For

All rose species and varieties including hybrid teas, floribundas, climbing roses, miniature roses, and David Austin varieties.

Frequently Asked Questions

How do I use GT Rose Focus correctly?

Shake GT Rose 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 Rose Focus with all plant types?

GT Rose 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 Rose 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 Rose 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 Rose Focus ship fast within Australia?

Yes — GT Rose 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.
