The Science of Moorland Nutrition

The Special Fertilizer Formula "Ericaceae Power"

Rhododendrons and azaleas as moorland plants have very special nutrient requirements that differ fundamentally from other garden plants:

• Acidic pH for optimal uptake: Moorland plants require a pH between 4.5 and 6.0 for optimal nutrient uptake. Our formula is specially developed for this acidic range and prevents nutrient blockages that occur in neutral or alkaline soils.
• Iron in chelated form: Iron deficiency is the most common problem with rhododendrons and azaleas. Our fertilizer contains iron in specially chelated form that remains optimally available even at unfavorable pH values and prevents chlorosis.
• Magnesium for flowering splendor: Magnesium is essential for chlorophyll formation and intense coloring of flowers. A deficiency leads to pale flowers and yellowish leaves. Our formula ensures optimal magnesium supply.
• Potassium for winter hardiness: Potassium strengthens cell walls and significantly increases frost resistance. Particularly important for overwintering the sensitive flower buds that are already formed in autumn for the next year.
• Phosphorus for root development: The shallow, fine root system of moorland plants requires optimal phosphorus supply for healthy development and efficient nutrient uptake.
• Trace element cocktail: Manganese, zinc, boron and other micronutrients are contained in the special composition that moorland plants need for optimal metabolic processes.
• Nitrogen in moderate dosage: Too much nitrogen makes rhododendrons susceptible to fungal diseases and frost damage. Our balanced formula promotes healthy growth without over-fertilization.
• Sulfur for soil acidification: Sulfur supports natural soil acidification and creates optimal conditions for nutrient uptake.
• Calcium in balanced amount: While too much calcium is harmful, moorland plants also need basic supply for stable cell walls and healthy development.
• Complex compounds for instant effect: All nutrients are present in state-of-the-art complex compounds that are immediately plant-available and don't need to be broken down by soil processes first.

Frequently Asked Questions (FAQ)

How often should I fertilize my rhododendrons and azaleas?

Every 14 days from March to October with root fertilization. With deficiency symptoms additionally weekly foliar fertilization for quick help.

Why do the leaves of my rhododendrons turn yellow?

Usually iron deficiency due to too high pH or lime-containing water. Use our special fertilizer with chelated iron and soft water.

Can I use the fertilizer for blueberries too?

Yes, the fertilizer is suitable for all acid-loving plants, including blueberries, cranberries and other Ericaceae.

My azaleas bloom poorly - what can I do?

Intensive fertilization after blooming is crucial for bud formation for next year. Additionally ensure acidic pH and sufficient moisture.

Does the fertilizer work for container plants too?

Perfect for container rhododendrons and indoor azaleas. For pot culture fertilize weakly year-round, reduce fertilization in winter.

What water should I use for fertilizing?

Soft, lime-free water is ideal. Rainwater or distilled water are perfect. Hard tap water can cause nutrient blockages.
