CompleteGrow Launches New Citrus Fertiliser to Improve Flowering, Fruit Set and Tree Health Across Australian Gardens

CompleteGrow has launched a new citrus-specific fertiliser formulated to improve flowering, fruit set, and overall tree health in lemon, lime, orange, and mandarin trees. The potassium-rich formula is designed to address common nutritional imbalances that cause yellowing leaves, poor flowering, and inconsistent fruit production in Australian gardens.

CompleteGrow Citrus Fertiliser

Sydney, NSW, Australia, 29th Jan 2026 — Australian plant nutrition brand CompleteGrow has launched its latest citrus-specific fertiliser. It helps home gardeners achieve greener foliage, stronger flowering, improved fruit set, and healthier citrus trees. The product works across varieties including lemons, limes, oranges, mandarins, and grapefruit.

The newly released product, available as a citrus fertiliser, has been formulated specifically to support the biological needs of citrus trees, delivering balanced nutrition for both vegetative growth and reproductive performance.

Citrus trees remain among the most popular fruit trees in Australian backyards, but they are also frequently reported as problem plants. Gardeners often face yellowing leaves, excessive leafy growth without flowering, poor fruit set, and inconsistent harvests.

Nutrient-Balanced Citrus Care

According to CompleteGrow, these issues usually stem from nutritional imbalances rather than pests or disease. The new product directly addresses this gap.

The fertiliser features a nutrient profile with an NPK ratio of 6-2-12. This provides moderate nitrogen for healthy leaf growth, phosphorus for root and early reproductive development, and elevated potassium to support flowering, fruit set, and fruit maturation.

“Citrus trees are heavy feeders and require specific nutrients,” said a CompleteGrow spokesperson. “Many gardeners use general-purpose fertilisers that supply nitrogen but lack enough potassium and essential trace elements. Potassium supports carbohydrate transport, water regulation, flowering, and fruit development — all areas where citrus trees often struggle.”

Micronutrient-Enriched Citrus Fertiliser

The fertiliser also includes chelated trace elements such as iron, zinc, manganese, boron, and copper. These micronutrients support chlorophyll production, enzyme function, and cell development. They help trees avoid leaf yellowing, poor vigour, and reduced productivity.

CompleteGrow notes that understanding the nutritional needs of citrus trees is a key step toward better production. The company has previously shared in-depth guidance explaining
why citrus trees struggle to fruit, outlining how imbalances in nutrients, watering inconsistency, and insufficient sunlight can disrupt flowering and fruit set.

Unlike many ornamental garden plants, citrus trees are evergreen fruit producers that remain active for much of the year. They continually produce leaves, roots, flowers, and fruit — all of which draw on soil nutrient reserves. Without replenishment in the right proportions, trees can quickly show signs of stress.

Supporting Holistic Citrus Care

While nutrition plays a central role in optimal citrus performance, CompleteGrow emphasizes that fertiliser works best when combined with sound horticultural practices.

These include:

• Providing at least six hours of direct sunlight daily
• Using well-draining soil or potting mix
• Deep, consistent watering during active growth
• Mulching to conserve moisture and protect root systems
• Light pruning to maintain airflow and reduce disease risk

For gardeners seeking broader guidance, CompleteGrow offers a complete resource on
how to plant, grow and care for citrus trees, covering planting techniques, seasonal care, and long-term strategies for thriving citrus.

Designed for Modern Australian Gardening

The fertiliser suits both in-ground and potted citrus trees. Container gardening on balconies, patios, and urban spaces is increasingly popular. Potted trees need more frequent nutrition due to regular watering and limited soil volume. This fertiliser provides consistent, balanced feeding for all environments.

“Many gardening recommendations are based on overseas climates and soils,” added the spokesperson. “Australian soils often lack organic matter and micronutrients, so our formulation performs reliably under local conditions.”

Early feedback from gardeners has highlighted visible improvements in leaf colour, stronger flowering, and more reliable fruit set within weeks of use — affirming the fertiliser’s practical value.
