Orange Tree Liquid Fertiliser - Set 2x1 liter

Enhanced Growth & Vigor for Orange Trees

Organifer Orange Tree Liquid Fertiliser delivers the ideal nutrient balance to support vigorous growth in Citrus × sinensis. Orange trees demand steady feeding through the season, particularly during flowering and fruit sizing. The 2-1-8 formulation strengthens foliage development, improves branch structure, and ensures the tree maintains a stable energy supply for blossoms, young fruitlets, and mature oranges.

Improved Flowering, Fruit Set & Sweetness

Orange blossoms are famously fragrant, and their successful transition into fruit requires potassium-rich nutrition. This fertiliser boosts bloom density, supports strong pollination, and improves the retention of small fruits. High potassium enhances sugar accumulation, resulting in sweeter, juicier oranges with vibrant colour. Amino acids further stimulate metabolic activity during reproductive growth, helping the tree direct energy toward consistent fruiting.

Strengthened Root Systems & Better Nutrient Uptake

Orange trees thrive when roots can access a steady supply of nutrients, moisture, and oxygen. Organifer's liquid formulation improves soil biological activity and enhances nutrient mobility around the root zone. Amino acids boost early root formation, stress resistance, and overall nutrient uptake efficiency—especially valuable for young trees, potted oranges, and trees recovering from pruning or cold damage.

Increased Resilience Against Heat, Drought & Environmental Stress

Citrus trees naturally experience seasonal stresses, including high summer heat, dry spells, or irregular watering. This fertiliser improves internal water regulation, strengthens cell structure, and enhances the tree’s ability to cope with heat or temporary drought. The potassium-focused formula also helps protect fruit quality during challenging conditions, reducing splitting, drop, or bitterness.

Suitable for All Orange Types, Including Sweet Oranges & Patio Citrus

Whether grown in orchards, greenhouses, containers, or home gardens, Organifer Orange Tree Liquid Fertiliser supports all Citrus × sinensis varieties. It is equally effective for sweet orange, Valencia, blood orange, Navel orange, and compact patio or dwarf citrus varieties. The balanced 2-1-8 formula ensures consistent growth and fruiting performance across different climates and planting systems.

Enhanced Foliage Health & Long-Term Tree Vitality

Healthy leaves are essential for sugar production and fruit sweetness. This fertiliser enriches foliage colour, strengthens leaf tissue, and reduces chlorosis by ensuring accessible potassium, magnesium, and calcium. Amino acids promote robust photosynthesis and improve recovery from environmental stress, ensuring long-term, productive trees with glossy, deep-green leaves.

Dosage

Number of applications: 2–3
Start: At early growth
Repeat: Every 2–3 weeks
Foliar spraying: 4–11 ml per 1 litre of water
Fertigation: 1–2 ml per 1 litre of water
Standard dose: 9–11 L per ha

Provide full sun, as oranges need abundant light to develop sweetness and strong fruit colour. Maintain steady soil moisture, avoiding alternating drought and flooding, which negatively affects fruit quality. Apply high-potassium feeding consistently to support fruit sizing and peel development. Protect trees from cold winds, as citrus is sensitive to low temperatures, and keep soil slightly acidic to neutral for efficient nutrient uptake. Light pruning after harvest encourages a balanced structure and better airflow, supporting both yield and tree health.

Storage

When stored under stable, frost-free conditions and protected from direct sunlight, this liquid fertiliser maintains its quality for an extended period. Closed containers preserve the formulation effectively, while any diluted solution should be used promptly to ensure optimal performance and purity.
