## Description

## Grassmaster – The Ultimate Fertiliser for Lawns, Plants, Fruits & Vegetables

### Struggling with Poor Growth and Dull, Weak Plants?

Whether you're tending to a lawn, garden, orchard, or vegetable patch, achieving lush greenery and healthy plant growth can be challenging. Patchy grass, weak plants, and nutrient-deficient soil can limit the beauty and productivity of your outdoor space. Many fertilisers offer short-term results, but they often fail to provide sustained nourishment for both lawns and plants.

### Grassmaster® – A Complete Fertiliser for Every Green Space

Grassmaster® is a high-performance fertiliser designed to **boost the health and vitality of lawns, plants, fruit trees, and vegetables**. With a **balanced mix of nutrients, organic bio-stimulants, and soil-enhancing minerals**, it promotes strong root development, deep green colour, and abundant growth across all types of vegetation.

### Why Grassmaster® Works Better

Grassmaster® delivers superior, long-lasting results through an advanced formulation:

- **Slow-Release Nitrogen & Phosphorus** – Specially coated Black Urea® and Black DAP™ reduce nutrient loss, ensuring steady growth with fewer applications.

- **Rich in Organic Bio-Stimulants** – Contains **humic and fulvic acids** to improve nutrient absorption, particularly iron and phosphorus, enhancing both root and leaf development.

- **Soil-Enhancing Minerals** – Includes **4% calcium** to balance soil pH and counteract acidity from fertilisers, improving plant health and resilience.

- **Complete Nutrition for All Plants** – Fortified with **poultry manure, sulphate of potash, and Green Cal (natural gypsum)** for optimal growth across lawns, flowers, vegetables, and fruit trees.

- **Easy Application** – 4mm granules ensure effortless spreading and uniform coverage.
