The Science of Wisteria Nutrition

The Wisteria Specialized Fertilizer Formula with Extra Phosphate and Potassium

Wisteria and laburnum, as vigorous climbing plants, have special nutrient requirements for optimal flower formation:

• Extra Phosphorus (P) for Flower Abundance: Intensively stimulates flower bud formation and ensures abundant, long-lasting flower clusters. Phosphorus is the key to spectacular wisteria blooms.
• Extra Potassium (K) for Stability: Strengthens shoot structure and increases resistance of long flower clusters. Potassium makes flowers more stable and durable.
• Nitrogen (N) for Growth: Promotes vigorous shoot growth, but balanced to avoid excessive leaf growth.
• Calcium (Ca) for Cell Stability: Important for stable cell walls in long shoots and heavy flower clusters.
• Magnesium (Mg) for Chlorophyll: Central atom of chlorophyll, important for rich green leaves and optimal photosynthesis.
• Iron (Fe) for Chlorophyll Synthesis: Prevents chlorosis (yellowing) of leaves and ensures healthy green coloration.
• Manganese (Mn) for Enzyme Activity: Important for photosynthesis and metabolic processes in large leaf masses.
• Boron (B) for Flower Quality: Essential for flower formation and pollen development, significantly improves flower quality.
• Complex Compounds: Chelated nutrients for optimal uptake through roots and large leaf surfaces.
• pH Buffer System: Stabilizes pH value for optimal nutrient availability.
• Flower Stimulators: Special compounds to promote flower bud formation.

Problem Solving Through Targeted Nutrient Supply

Common Wisteria Problems and Their Solutions

• Weak or no flowering: Phosphorus deficiency → Enhanced fertilization with phosphate-rich fertilizer
• Light green leaves: Nitrogen or iron deficiency → Regular foliar spraying
• Too much leaf growth without flowers: Over-fertilization with nitrogen → Phosphate-potassium focused fertilization
• Short flower clusters: Nutrient deficiency → Intensive fertilization before flowering time
• Leaf drop: Stress or drought → Even watering and gentle fertilization
• Weak growth: Nutrient deficiency → Regular root and foliar fertilization

Effects of Optimal Fertilization (from Customer Experience)
