    Why Choose Our 20kg Lawn Fertiliser?

    If you’re serious about creating a stunning, moss-free lawn, our 20kg lawn fertiliser is the go-to choice. Its balanced composition ensures rapid establishment and sustained growth, making it the ideal partner for sowing new lawn seed or rejuvenating established turf. With a slow-release action and moss-suppressing ingredients, you’ll see greener blades faster and a noticeably thicker sward.

    This fertiliser is versatile enough for all major NZ lawn types, especially when used alongside popular seed varieties. Try pairing it with Fine Fescue Lawn Seed for a soft, elegant finish, Tall Fescue for exceptional drought tolerance, or Amenity Ryegrass Seed (Lawn Seed) for quick establishment and hard-wearing lawns. It also complements warm-season grasses like Pure Kikuyu Seed.

    Key Benefits for Lush Growth and Moss Control

    Our 20kg lawn fertiliser works on two fronts: it promotes vigorous growth, and it takes care of moss so your lawn stays clean and healthy. The unique nutrient profile includes nitrogen for leaf development, potassium for resilience, and phosphorus for strong roots. Moss can overtake lawns in New Zealand’s moist, shady areas, but this fertiliser addresses the root causes, leaving your lawn neat and moss-free.

    If you’re planting new turf, combine this fertiliser with our New Lawn Fertiliser for even stronger starts, and consider sowing in a 198-Cell Tray for easy, organised planting.

    How to Use 20kg Lawn Fertiliser for Best Results

    Applying 20kg lawn fertiliser is straightforward and perfect for large yards or multi-area coverage. Spread evenly across your lawn, following the bag instructions. For optimal results, fertilise during the active growing season – typically spring and autumn in NZ. Water thoroughly after application and avoid mowing for a few days to allow nutrients to absorb.

    For year-long feeding, you can combine with 12-months controlled release fertiliser, ensuring your lawn receives a consistent supply of nutrients. Use a high-quality planter like our Medium Vienna Planter - Eucalyptus for transplanting lawn plugs or surrounding garden beds.

    Expert Tips for Moss-Free Lawns in NZ

    Keep your lawn moss-free by improving drainage, maintaining regular feeding routines, and controlling weeds. If moss persists, consider using a specialised herbicide such as Banvine - 1 Litre, while shaded areas can be managed with Shadecloth - 30% Shade (1.8 m wide in a 50 metre roll).
