Description
High-Potassium Mineral Blend to Boost Bloom, Fruit & Root Development
Slow-release (4-6 months) NPK fertiliser with extra minerals for blooms, flavour and soil fertility
If your flowers are fading fast or your veggies lack flavour, it’s probably not just water they’re missing, it’s balanced nutrition. Flowers, Fruits & Roots is a premium granular fertiliser designed to feed your plants and the soil. It delivers slow-release nutrients along with natural minerals and trace elements to boost colour, taste, and yield, all while improving long-term soil health. Whether you're aiming to boost flowering and fruit set, improve slow plant growth or poor yields, or you've noticed a drop in flavour, colour, or harvest quality, Flowers, Fruits & Roots has you covered. It's especially helpful if soil tests reveal mineral depletion, or if you're simply looking to rebuild long-term soil fertility while encouraging healthier, more productive plants.
Flowers, Fruits & Roots is a high-potassium fertiliser specifically formulated to support flowering and fruiting plants and trees. It helps strengthen trunks and roots, boost seed germination, and stimulate beneficial soil microbes for healthier growth. With added bio-protection against disease, improved moisture retention, and the ability to increase Brix (sugar) levels, this blend promotes both plant resilience and harvest quality.

How it Works

At its core, Flowers, Fruits & Roots is a strategically formulated mineral-based fertiliser tailored to support reproductive growth (flowers and fruit) and root architecture across a broad range of plants.
- High Potassium (K) at 20% encourages floral initiation, fruit fill, and colour development, while increasing plant resilience to drought and disease.
- Phosphorus supports root development and bloom quality, but is kept at a balanced 2% to avoid overstimulation in phosphorus-sensitive species.
- Sulfur (8.84%), Calcium (3.79%), and Magnesium (0.56%) help with enzyme activation, cell wall integrity, and chlorophyll production — all essential during high metabolic periods like flowering and fruiting.
- The Silica (6.89%) content aids in strengthening cell walls, making plants more resistant to pests and environmental stress.
- Trace elements like Iron, Zinc, Manganese, Copper, and Boron are present in bioavailable forms to correct micronutrient deficiencies that often limit fruit set and flower development.
- The inclusion of Cobalt and Molybdenum, though in minute amounts, plays a vital role in nitrogen fixation and hormonal balance, especially in legumes and flowering shrubs.
- Granular delivery ensures slow, steady nutrient release, reducing leaching and enhancing root zone microbial activity for long-term soil fertility.
This isn’t just a fertiliser, it’s a biological strategy for maximising flowering cycles, boosting fruit yields, and supporting root anchorage, all while improving soil health.

Excellent All-Round Fertiliser for Productive Gard
We’ve had consistently great results using Flowers, Fruits & Roots Granular Fertiliser across a range of ornamental and edible gardens throughout SE Queensland. It promotes healthy growth, strong flowering, and noticeable improvement in overall plant vigour. We’ve particularly liked the balanced response across flowering shrubs, fruiting plants, and root development in newly established gardens. Easy to apply and a reliable product to keep on hand for ongoing garden maintenance and seasonal feeding.

Tons of tomatoes and capsicum thanks to this product.
I'll be buying more!
I recently purchased the small 1kg bag as a bit of a trial to use in one of our gardens containing a number of 'Red Robins'. All I can say is wow! There has been an explosion of amazing new red growth in quite a seemingly short period of time. In the past I had used other branded & common liquid and granular ferts with little noticeable difference. But I'll definitely be buying more Flowers, Fruits & Roots Granular Fertiliser for all of our gardens!
