Watermelon Liquid Fertiliser - 10 liters

Balanced Nutrition for Vigorous Watermelon Growth

Organifer Watermelon Liquid Fertiliser is formulated to support healthy vine development and high-quality fruit production in watermelon crops. The 2-1-8 nutrient balance provides potassium-focused nutrition that supports flowering, fruit set, and internal fruit quality while keeping vegetative growth under control. This balanced approach helps watermelon plants channel energy efficiently from vine growth into fruit development.

Strong Vine Development and Flower Formation

During early growth, watermelon plants require steady nutrition to build strong, flexible vines capable of supporting heavy fruit load later in the season. This liquid fertiliser supports uniform shoot development and healthy leaf formation without overstimulating excessive vine growth, creating a stable foundation for flowering and pollination.

Improved Fruit Set and Uniform Development

Potassium plays a central role during flowering and early fruit formation. Regular application supports better flower retention, improved fruit set, and more uniform fruit sizing. This leads to a higher percentage of marketable fruits with consistent shape and internal structure.

Enhanced Fruit Quality, Firmness, and Internal Structure

As watermelons enlarge, potassium supports sugar transport and water regulation within the fruit, while calcium and magnesium contribute to firm flesh and reduced internal disorders. Consistent feeding helps reduce the risk of hollow heart and improves overall eating quality, firmness, and shelf life.

Improved Stress Tolerance and Nutrient Uptake

Watermelon plants are sensitive to fluctuations in moisture and temperature. The organic components of this liquid fertiliser support improved nutrient uptake and internal balance, helping plants maintain steady growth during warm periods, rapid fruit expansion, and high crop demand.

Suitable for Open Field, Raised Beds, and Greenhouse Cultivation

This fertiliser is suitable for watermelons grown in open fields, raised beds, tunnels, and greenhouse systems. It performs well in both soil-based cultivation and fertigation systems, making it suitable for home gardeners and professional growers alike.

Dosage

Number of applications: 4–7
Start: At early growth
Repeat: Every 10–14 days
Foliar spraying: 3–9 ml per 1 litre of water
Fertigation: 1–2 ml per 1 litre of water
Standard dose: 5–9 L per ha

For optimal performance, maintain steady soil moisture throughout flowering and fruit set, as watermelons are highly sensitive to drought stress during these stages. Ensure sufficient calcium and magnesium availability to help prevent hollow heart and improve flesh firmness. Avoid excessive nitrogen, which can lead to excessive vine growth and reduced fruit quality. Strong pollination conditions are essential for uniform fruit development, and maintaining good airflow within dense canopies helps reduce disease pressure and supports healthy growth.

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.
