Garden Addicts SteadyGro - 6mth Slow Release Fertiliser (Covers 500m2) - - - [10kg]

Covers 500m2

Long-lasting nutrition for thriving gardens. Premium slow-release feeding works continuously for up to six months, supporting healthy, vigorous growth all season long.

One application at the start of the season covers your base nutrition through 2 seasons! The coated urea releases nitrogen gradually as soil temperature rises, which means plants get a consistent supply rather than a short spike followed by nothing. That steady release also means no burn risk and minimal nutrient loss through leaching.

The NPK is genuinely balanced for general garden use: 18% nitrogen for growth and colour, 6% phosphorus for root establishment, and 12% potassium for plant strength and stress tolerance. The secondary nutrients round it out well: 0.5% magnesium, 6.8% sulphur and trace iron, manganese, and zinc.

NPK is 18-6-12

How to use

Garden beds and general planting areas

Spread evenly across the soil surface and water in, or mix lightly into the top few centimetres of soil. Apply at the start of the growing season. A second application mid-season is optional for heavy-feeding plants.

New plantings, fruit trees, and shrubs

Apply at the lower rate and mix lightly into the soil around the root zone. Do not place directly under the root ball. Water in thoroughly after planting.

Potted plants and planter boxes

Apply to the surface and water in. Pots heat up faster than garden beds, which can accelerate the release rate slightly, so stick to the lower end of the application rate.

Pairing with liquid fertilisers

SteadyGro handles the base nutrition. Top up monthly with a compatible liquid fertiliser to support active growth and maintain soil health through the season. This is where the programme really performs.
