Magnesium is an essential nutrient that plays a central role in the health, vitality & productivity of plants, particularly during key growth & flowering stages.

  • Core to Photosynthesis – Magnesium is the central element in chlorophyll, making it essential for photosynthesis. More energy means stronger growth and healthier, more vibrant plants.

  • Energy Production & Transfer – It helps activate enzymes and plays a role in producing and transporting energy within the plant, fueling everything from root development to flowering.

  • Boosts Flowering & Fruit Quality – Adequate magnesium supports the movement of sugars and nutrients to developing flowers and fruits, improving size, quality, and overall yield.

  • Prevents Deficiencies – A lack of magnesium often shows as yellowing between the leaf veins. Keeping levels topped up maintains lush, green growth—critical during flowering.

  • Supports Stress Resistance – Magnesium improves a plant’s ability to tolerate drought, heat, and other stresses, keeping it productive and resilient throughout its life cycle.
