Hydrangea Success: GREEN24 Specialized Fertilizer for Hydrangea & Acid-Loving Plants

Successful cultivation of hydrangeas requires special knowledge about the needs of these spectacular flowering shrubs. Hydrangeas, as acid-loving moorland plants, have completely different nutrient requirements than normal garden plants and need particularly balanced care with trace nutrients for abundant flower formation. Our Hydrangea Fertilizer is specifically tailored to the needs of Hydrangea and related acid-loving plants and offers professional hydrangea technology for maximum success.

The Science of Hydrangea Nutrition

The Hydrangea Specialized Fertilizer Formula "Flowers and Structure"

Hydrangeas, as acid-loving moorland plants, have special nutrient requirements for optimal flower formation:

• Nitrogen (N) for vigorous growth: Promotes the formation of rich green leaves and strong shoots. Balanced for healthy growth without over-fertilization.
• Phosphorus (P) for flower abundance: Intensively stimulates flower bud formation and ensures abundant, long-lasting flower balls. Phosphorus is the key to spectacular hydrangea blooms.
• Potassium (K) for stability: Strengthens cell structure and increases resistance to drought and diseases. Potassium makes hydrangeas robust and winter hardy.
• Iron (Fe) against chlorosis: Prevents iron deficiency chlorosis (yellowing) of leaves and ensures rich green coloration. Particularly important for acid-loving plants.
• Magnesium (Mg) for chlorophyll: Central atom of chlorophyll, important for rich green leaves and optimal photosynthesis.
• Calcium (Ca) for cell stability: Important for stable cell walls, but controlled dosage to avoid raising pH value.
• Manganese (Mn) for enzyme activity: Important for photosynthesis and metabolic processes, prevents manganese deficiency chlorosis.
• Boron (B) for flower quality: Essential for flower formation and cell wall construction, significantly improves flower quality.
• Trace element complex: Complete spectrum of all important micronutrients for optimal plant health.
• Complex compounds: Chelated nutrients for optimal uptake even at unfavorable pH values.
• pH buffer system: Stabilizes the acidic pH range for optimal nutrient availability.
