NPK Fertilisers
NPK fertilisers are essential plant nutrients that provide the three most important elements needed for healthy plant growth: Nitrogen (N), Phosphorus (P), and Potassium (K). Each element plays a vital role – Nitrogen promotes leaf and stem growth, Phosphorus helps develop strong roots and flowers, while Potassium improves overall plant health and disease resistance. Think of NPK as your plants’ complete nutrition package, much like a balanced diet is essential for human health. Whether you’re growing vegetables, maintaining a lush lawn, or nurturing flowering plants, using the right NPK ratio ensures your plants get the perfect balance of nutrients they need to thrive.
