10-4-4+TE Nutrigrow Spring-Rise Fertiliser 20kg

The numbers outline the fundamental NPK macronutrient breakdown: 10% nitrogen for rapid leaf growth and greening, 4% phosphate to build strong root structures, and 4% potassium to increase overall disease and drought resistance. The ‘+TE’ stands for Trace Elements, indicating the product is fortified with essential micronutrients.

Beyond the standard NPK mix, this product is packed with secondary micronutrients: 8% calcium to reinforce plant cell walls, 4% magnesium to boost chlorophyll production, and 3% iron (ferrous sulphate) to rapidly intensify the green colour of the turf.

One 20kg bag provides total treatment coverage for up to 570 square meters of turf when applied at the lower calibration rate. The exact area you achieve will vary depending on whether you choose a light maintenance application or a heavier recovery dose.

Between 35 grams and 70 grams per square meter. Sticking to the lower 35g rate is perfect for steady spring maintenance, while the higher 70g rate should be reserved for grass that is highly stressed or suffering from visible nutrient deficiencies.

The product features mini-compound granules measuring between 1mm and 2.5mm in size. This compact, uniform granule sizing ensures an excellent, even spreading pattern across the turf, preventing patchy growth and minimising the risk of accidental chemical scorch.

This organic-based compound is designed to gradually release its macro and micronutrients into the soil over a 6-week period. This steady breakdown ensures prolonged grass health, avoids ugly growth spikes, and keeps the sward lush for longer.

It is highly versatile and officially safe for use on domestic lawns, horse paddocks, livestock pastures, sports turf, playing fields, and general amenity grass. It can also be safely applied to new grass or distributed around established trees, shrubs, and conifers.

As the name suggests, the prime application window spans across the spring and summer months when the grass is actively growing and can fully absorb the nutrients. For the best start to the growing season, apply it early in the year to kick-start sluggish turf.

While you can cast the granules by hand on very small garden plots using protective gloves, using a calibrated push spreader is highly recommended for larger areas. This guarantees uniform coverage and prevents the uneven green striping caused by inconsistent manual spreading.

No, you should avoid mowing your lawn for 3 to 4 days either side of applying the fertiliser. Leaving the grass undisturbed gives the mini-granules time to settle down into the base of the turf sward and dissolve safely into the root zone after rainfall.
