Frequently Asked Questions
What do the numbers 6-9-6 represent in this product?
The numbers indicate the percentage of the three core macronutrients included in the mix, specifically 6% nitrogen, 9% phosphate, and 6% potassium. This formulation is intentionally weighted toward phosphate to stimulate rapid root development rather than excessive top leaf growth.
What size pack does this Nutrigrow pre-seeder fertiliser come in?
This product is supplied by Agrigem in a 20kg bag.
What is the recommended application rate for this fertiliser?
The specified spreading rate ranges between 20 grams and 50 grams per square meter depending on the baseline condition of your soil. Using a lower rate is suitable for general maintenance, while the higher end is ideal for nutrient-deficient ground.
How much total lawn area will a single 20kg bag cover?
A single 20kg bag will cover a maximum area of up to 1000 square meters if applied at the lighter 20-gram rate. If you apply the product at the maximum recommended thickness of 50 grams per square meter, one bag will cover 400 square meters.
When is the best time to apply a pre-seeder fertiliser?
The ideal periods of use are autumn, spring, and winter. You should aim to spread the granules up to 2 weeks before sowing your grass seed or laying turf, though it can also be applied at the exact same time as seeding.
Why is this specific formula better for new grass than a standard summer fertiliser?
It is formulated as a mini-granule compound with relatively low, balanced nutrient levels to prevent chemical scorching on young and tender grass blades. Standard high-nitrogen fertilisers are too intense for new shoots, whereas this mix releases its nutrients safely over a steady 6-week period.
What specific benefits do the individual nutrients provide to the new seeds?
The high 9% phosphate focus assists the plant in turning nutrients into usable building blocks to rapidly accelerate root structure development. Meanwhile, the 6% nitrogen aids early photosynthesis for a quick green-up, and the 6% potassium regulates carbon dioxide uptake to build plant hardiness.
Is this product limited strictly to residential lawns?
No, it is a highly versatile compound designed for a wide range of turf and growing environments. It is officially approved for use on paddocks, pastures, residential lawns, sports turf, horticulture projects, and surrounding amenity vegetation.
Can I safely let pets and children onto the treated area?
You should keep children and pets away from the treated zones until the fertiliser granules have been completely washed into the soil and the grass has dried. Applying the product immediately before expected light rain or watering the ground thoroughly yourself will speed up this process safely.
What is the best method for applying these granules evenly?
While you can spread the granules by hand using protective gloves or with a hand spreader. We recommend using a calibrated fertiliser spreader however to ensure a consistent spreading pattern across the entire area and prevents the uneven growth or patchy colouring that comes from irregular manual casting.
