Neutrog Kahoona 4kg – Fertiliser for Camellias, Gardenias, Azaleas & Acid-Loving Plants

Neutrog Kahoona 4kg: Made for Camellias, Gardenias, Azaleas and Rhododendrons

Neutrog Kahoona is an organic-based, chemically boosted fertiliser developed to improve the growth and flowering of acid-loving plants such as camellias, gardenias, azaleas and rhododendrons. Its higher potassium to nitrogen ratio supports bud and flower development, while boosted iron and magnesium keep foliage a healthy deep green. Suited to both garden beds and pots, the 4kg tub is a practical size for gardens with several established shrubs.

Endorsed by Australian Camellia and Rhododendron Societies

Kahoona was put through trials with specialist growers before release, and the results earned it the endorsement of Camellias South Australia, the Australian Rhododendron Society (SA Branch), the Camellia Society of WA and Camellias Illawarra. When the people who grow these plants for shows and collections recommend a fertiliser, home gardeners can use it with confidence.

Stopping the Yellow Leaves Before They Start

Camellias, gardenias and azaleas often show yellowing leaves in late winter and early spring, usually a sign they are short of iron or magnesium. Kahoona contains boosted levels of both, helping keep leaves green and glossy through the seasons. Gardenias in particular are prone to yellowing, so regular feeding with a fertiliser built for acid-loving plants makes a visible difference.

Organic Carbon That Holds Nutrients in the Soil

Each Kahoona pellet contains the full range of major and trace nutrients, plus good levels of organic carbon. That organic carbon helps hold the water-soluble nutrients in the soil so they are not washed straight through, and helps plants take them up evenly over time. The organic base also supports soil structure and beneficial microbial activity around the roots.

How to Apply Neutrog Kahoona

• Established plants: apply 100g per plant, spread around the drip line on moist soil, keeping pellets away from stems and foliage.
• Established potted plants: apply 15g for a 150mm pot, then add 5g for every extra 25mm of pot size.
• When to apply: start once new season growth appears, then repeat every 8 to 10 weeks from spring to autumn. Use Neutrog Seamungus over winter.
• New plantings: Neutrog recommends Seamungus at 100g per plant at planting time, then Kahoona once the plant is established.

Water in well after every application. Rates are a guide only and may need adjusting for your soil and climate.

Keeping Acid-Loving Plants Happy

Kahoona feeds acid-loving plants, but it does not change the soil pH, so soil conditions still matter. These plants prefer a slightly acidic, free-draining soil rich in organic matter. Mulch with pine bark or leaf litter to keep roots cool and moist, and keep garden lime and limey materials well away from them. For pots, use a potting mix made for camellias and azaleas rather than a general mix.
