Growth Technology Rose Focus is a complete, balanced rose nutrient made to promote magnificent blooms and support long-term plant health with a precision formulated nutrient profile. It’s a targeted rose fertiliser and plant nutrient for gardeners who want stronger flowering performance from their roses.
Rose Focus is specifically formulated to help roses produce large, vibrant blooms, with an emphasis on abundant flowering and overall plant vitality. A key differentiator is the inclusion of extra calcium in a highly soluble form, selected to help increase disease resistance while supporting sturdy, healthy growth. If your roses are pushing new shoots, setting buds, or carrying flowers, this balanced approach supports the plant through the full cycle without feeling like a one-stage-only product.
Because it’s part of the GT Focus range, Rose Focus is a complete, balanced nutrient that contains all 12 essential minerals. That matters for consistent performance over time, especially when roses are grown in containers or in changing seasonal conditions where nutrient availability can vary. The formula is highly bioavailable, helping plants access nutrition efficiently, and it’s manufactured using high grade raw materials and chelated trace elements to support effortless absorption. In plain terms, it’s designed to deliver dependable mineral nutrition without leaving key essentials behind.
Rose Focus is also pH buffered, with no pH adjustment needed when used with most tap water, which helps keep routine feeding more consistent. For growers who prefer a cleaner input profile, it’s guaranteed not to contain potentially harmful and ineffective chlorides, urea and sodium. It’s completely odourless as well, making it an easy fit for patios, balconies, greenhouses, and indoor plant spaces where you want strong results without lingering smells.
For setup flexibility, Rose Focus is suitable for both hydroponics and soil. It’s positioned for vegetative growth, flowering, and mature plants, so it stays relevant as your roses move from leafy growth into bloom and onward through the season. Whether you’re maintaining established bushes or supporting newer plants as they build structure, this is a rose-specific nutrient built around balanced mineral coverage and bloom-focused support.
This is a good fit for rose growers who want a complete, balanced nutrient with highly bioavailable minerals, pH buffered stability, and extra calcium support for magnificent blooms and improved disease resistance in soil or hydroponic setups.
Step-by-step mixing and feeding instructions for Growth Technology Rose Focus - 1 Litre.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Growth Technology Rose Focus - 1 Litre well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.
Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.

Warning – Important Safety Information
This product may cause mild skin irritation and eye irritation. Avoid unnecessary contact with skin, eyes, and clothing. Use only as directed.
General safety precautions
Read and follow all instructions on the product label and any accompanying documentation before use. Keep out of reach of children and pets. Do not ingest. Avoid breathing vapours, mist, or dust that may be generated during handling or use.
Wear appropriate personal protective equipment (PPE), such as protective gloves, long sleeves, long pants and closed-toe footwear. When there is a risk of splashing or airborne particles, use safety glasses or other suitable eye and face protection.
First aid – skin contact
IF ON SKIN OR HAIR: Remove contaminated clothing immediately. Rinse skin with clean water for several minutes, then wash with mild soap and water. If irritation or redness develops and persists, seek medical attention. Wash contaminated clothing before reuse.
First aid – eye contact
IF IN EYES: Rinse cautiously with clean water for several minutes, keeping eyelids open. Remove contact lenses if present and easy to do. Continue rinsing. If irritation persists, obtain medical advice.
First aid – ingestion and inhalation
IF SWALLOWED: Rinse mouth thoroughly with water. Do not induce vomiting unless instructed by a medical professional. Seek medical attention if you feel unwell.
IF INHALED: Move the person to fresh air and keep them comfortable for breathing. If coughing, breathing difficulty, dizziness or other symptoms occur, seek medical assistance.

| Nitrate Nitrogen (N) | 1.8% |
|---|---|
| Available Phosphorus (P2O5) | 0.6% |
| Potassium (K) | 2.3% |
| Calcium (Ca) | 1.1% |
| Total Magnesium (Mg) | 0.5% |
| Sulfur (S) | 0.14% |
| Total Iron (Fe) | 0.04% |
| Total Manganese (Mn) | 0.012% |
| Boron (B) | 0.003% |
| Zinc (Zn) | 0.003% |
| Copper (Cu) | 0.002% |
| Molybdenum (Mo) | 0.001% |
Available phosphorus supports root growth, energy production, and strong flowering by providing a form of phosphorus that plants can absorb immediately.
Boron is essential because it stabilizes cell walls, supports root and shoot growth, and regulates sugar movement throughout the plant. What makes boron unique is its limited mobility and extremely narrow range between deficiency and excess, which causes new growth to show symptoms rapidly when levels fall out of balance.
Calcium is important because it builds and stabilizes plant cells as they form, acting as the structural support that keeps new growth strong and functional. Unlike other nutrients that drive color or speed of growth, calcium’s role is unique because it controls cell wall strength and membrane stability, making it essential for healthy roots, shoots, and long-term plant resilience rather than quick visual results.
Copper is important because it powers key enzymes that support energy use, tissue strength, and stress protection, and it’s unique from many other micronutrients because plants need it in tiny amounts but can be harmed quickly if copper becomes excessive.
Molybdenum is important because it helps plants convert nitrogen into usable building blocks for chlorophyll and growth, and it’s unique from many nutrients because it mainly supports enzyme-driven “nutrient use” rather than directly building plant tissue.
Nitrate Nitrogen provides a stable, easy-to-absorb form of nitrogen that supports steady growth, strong foliage, and reliable plant development without sudden nutrient swings.
Potassium is important because it controls key plant systems like water regulation, sugar transport, and nutrient movement, which supports stronger stems and better flowering or fruit quality. It’s unique because it doesn’t mainly build plant tissue like other major nutrients—it helps the plant use and manage what it already has, so small imbalances can affect the whole plant.
Sulfur is important because plants need it to build key amino acids and proteins that drive real growth, strong structure, and efficient use of nitrogen, making it uniquely different from “look-alike” nutrients that may change leaf color without supporting the plant’s core building process.
Total iron (Fe) matters because iron supports chlorophyll development and plant energy systems, keeping new growth green and vigorous; it’s unique from many other nutrients because iron deficiency usually shows up first in young leaves even when older leaves stay green, since iron doesn’t easily move within the plant.
Total magnesium is important because magnesium powers chlorophyll and energy use, helping plants stay green, turn light into growth, and use other nutrients efficiently—and it’s unique because its problems often come from nutrient balance and uptake competition, not just a simple shortage.
Total manganese matters because it supports photosynthesis and enzyme activity that keep new growth green and vigorous, and it’s unique because “total” manganese measures what’s present but not necessarily what the plant can absorb—so pH and root conditions decide whether manganese helps or harms.
Zinc is important because it powers key enzymes and helps regulate growth hormones, which directly controls healthy new leaves, normal internode spacing, and strong growth tips; it’s unique compared to many other micronutrients because zinc problems often show up as distorted, undersized new growth and stunting, not just simple leaf yellowing.
