Looking for a premium controlled-release fertiliser Adelaide gardeners trust for long-lasting plant nutrition? Newton Building & Landscape Supplies stocks Osmocote All Purpose Fertiliser 4.5kg, a professional-grade fertiliser formulated to provide consistent feeding for flowers, vegetables, herbs, indoor plants, fruit trees, and Australian natives. Available for online order, delivery, or in-store pickup across Adelaide, it delivers balanced nutrition to support healthy growth, stronger roots, and vibrant foliage.

WHAT IS IT?

Osmocote All Purpose Fertiliser is an advanced controlled-release fertiliser featuring Scotts’ proven prill technology. Each granule is designed to release nutrients gradually, providing plants with the nutrition they need when they need it most. Nutrient release naturally increases during warmer growing conditions and slows during cooler periods, helping maximise efficiency while reducing nutrient waste.

The formula also contains a wetting agent to improve water penetration into soil and potting mixes, allowing nutrients to be more readily absorbed by plant roots. Added iron, magnesium, and trace elements help maintain greener foliage and healthier plant growth throughout the feeding period.
