Proper nutrition is key when growing potted olives and palms in northern Europe

When growing olives and palms in pots in the northern part of Europe, it is important to ensure proper nutrition throughout the entire vegetation cycle.

Olives require a balanced supply of nutrients, especially when grown in confined spaces. Below are recommendations on which liquid and granular fertilizers to use at different growth stages:

Beginning of the vegetation period (spring – early growth)
Liquid fertilizers:

VIVAGEL NPK 4-44-4 (for watering) or VIVAGEL PK 42-8 (for watering)

HUMIBOOST (for watering)

HUMIRIZ

Examples of granular fertilizers:

Complex NPK fertilizers: NPK 10-10-20 + Org.

Organic fertilizers: FRASSON

Mid-vegetation period (summer – intensive growth and flowering)
At this stage, it is important to promote flower formation and fruit setting.

Liquid fertilizers:

• VIVAGEL K40 (for watering or foliar application)
• HUMIBOOST (for watering)
• ALFA GREEN (foliar)
• PLANT STIM (foliar)

Examples of granular fertilizers:

• Complex NPK fertilizers: NPK 12-12-15 + Org

End of the vegetation period (autumn – fruit ripening and preparation for winter)
At this stage, the focus is on fruit ripening and preparing the plant for winter.

Liquid fertilizers:

• VIVAGEL K40 (for watering)
• PLANT STIM (foliar)
• HUMIRIZ (for watering)

Examples of granular fertilizers:

• Complex NPK fertilizers: NPK 10-10-20 + Org.

Winter period (dormant phase)
During winter, olives do not grow, so fertilization is unnecessary. However, it is important to protect plants from frost and excessive moisture.

General recommendations:

• Soil pH: Olives and palms prefer neutral to slightly alkaline soil (pH 6.5–7.5). If the pH is too low – apply lime.
• Irrigation: Ensure good drainage to prevent waterlogging.
• Micronutrients: Regularly supplement with micronutrients, especially iron, zinc, and boron – these are essential for healthy growth.ui.
