Which Fertilizer is Best for Panicle Hydrangeas

Hydrangea grows actively in spring and forms buds in early summer, so balanced fertilizers are especially important for it.

Key elements necessary for hydrangeas:

• Nitrogen (N) for growing greenery and new shoots.
• Phosphorus (P) for forming buds and root systems.
• Potassium (K) for strong shoots and flowering quality.
• Magnesium and Sulfur support leaf health.

Which fertilizers fit best:

• Spring: universal NPK 10-10-10, 12-8-12, 14-10-18.
• Summer (June July): potassium fertilizers NPK 8-4-12 or 5-3-12.
• Autumn (August September): only potassium and phosphorus.
