The Science of Gardenia Nutrition

The Gardenia Specialized Fertilizer Formula "Gardenia Pro"

Gardenias, as acid-loving plants, have special nutrient requirements for optimal development:

• Nitrogen (N) for leaf growth: Promotes formation of glossy, dark green leaves for maximum photosynthesis. Nitrogen is essential for healthy leaf growth and vigorous gardenias.
• Phosphorus (P) for flower formation: Intensively stimulates fragrant flower development and ensures rich, long-lasting flower splendor. Phosphorus is the key to spectacular gardenia flowers.
• Potassium (K) for stability: Strengthens the plant and increases resistance to stress. Potassium is important for stable branching and vitality.
• Magnesium (Mg) for chlorophyll: Central atom of chlorophyll, important for vigorous green leaves and optimal photosynthesis. Prevents yellowing of leaves.
• Iron (Fe) against chlorosis: Prevents iron deficiency chlorosis and ensures healthy, green leaves. Particularly important for acid-loving plants like gardenias.
• Sulfur (S) for pH value: Important for acidic pH range and protein synthesis, supports optimal nutrient uptake in gardenias.
• Trace element complex: Complete spectrum of all important micronutrients for optimal gardenia health.
• Complex compounds: Revolutionary technology for immediate nutrient availability and optimal uptake.
• Acid buffer: Special formulation for optimal pH range in acid-loving gardenias.

Frequently Asked Questions (FAQ)

When and how often should I fertilize my gardenias?

Fertilize your gardenias every 2-3 weeks during the growing season from March to October. Fertilization is particularly important during the growth and flowering phase in spring and early summer.

Can I use the fertilizer for both root and foliar fertilization?

Yes, our gardenia fertilizer is versatile. Use it as irrigation solution for sustainable root fertilization or as foliar spray for quick nutrient uptake in case of deficiency symptoms.

Why do the leaves of my gardenia turn yellow?

Yellow leaves usually indicate iron deficiency (chlorosis) or too alkaline substrate. Use lime-free water, acidic substrate and possibly additional iron fertilizer.

Why do the buds of my gardenia drop?

Bud drop usually occurs due to too dry air, location changes or water stress. Increase humidity, avoid location changes and water evenly.

What water should I use for my gardenias?

Gardenias prefer lime-free, soft water. Use rainwater or distilled water preferably. Hard tap water can lead to chlorosis and poor growth.

How can I extend the flowering period of my gardenias?

Regular fertilization, optimal humidity, even watering and a stable location extend the flowering period. Avoid stress factors during the flowering phase.
