When it comes to lawn maintenance - timing can be everything!! So we've put together a handy seasonal lawn maintenance guide to help you plan your lawn care. We all know that Australian Seasons can be harsh on turf, but give your lawn some extra attention through the year, and you will be rewarded with healthy, resilient grass that will last through the seasons.
This calendar is only a guide, and does not take into account regional or seasonal weather variations. Keep track of your local seasonal changes and always monitor your lawn's condition for any signs that your turf may need some extra care!

Spring Maintenance
Spring brings with it a time of growth and regeneration. A healthy lawn will compliment your colourful spring garden! It's the perfect time to get to work to prepare your garden for the hot summer to come with plenty of food and nutrients.
Bi-Agra wetting agent is a new innovation in the fight against hydrophobic soils. A moisture retaining aid as well it is great for lawns and gardens.
Freehand is a pre-emergent herbicide that prevents weeds from germinating. This powerful herbicide is labeled for the control and suppression of more than 60 of the toughest, most troublesome weeds.
Knights Coastal Special Lawn Mix is a granular fertiliser formulated specifically for the conditions Perth lawns face — sandy, free-draining coastal soils that leach nutrients quickly, and a climate that demands consistent colour and root health through both dry summers and cooler winters.
The balanced nutrient blend replenishes the nitrogen, potassium and trace elements that Perth's sandy soils cannot hold between applications. Unlike high-nitrogen products that push rapid lush growth, Knights Coastal is formulated for steady, sustained feeding — building genuine root depth and lawn density rather than quick but shallow top growth.
Apply with a rotary spreader at the recommended rate and water in immediately after spreading. Suitable for all lawn varieties including Sir Walter Buffalo, TifTuf, Zoysia Australis and Nullarbor Couch.
Best used as part of a year-round fertilising program with applications in autumn (April/May), late winter (August) and spring (October). The autumn application is the most critical — it builds the nutrient reserves the lawn draws on through winter.

Summer Maintenance
A lush green lawn in the summer makes spending time outside even more enjoyable. In Australia, we have hot dry summers, so we need to remember to keep the moisture up to help our lawns stay healthy. If dry patch occurs apply a liquid wetting agent. Liquid wetting agents work very quickly, however you also need to do your retic audit. Wetting agents can burn the lawn if enough water is not applied immediately to water them in.

Acelepryn GR is Australia's leading professional-grade insecticide for lawn pest control, used extensively by turf managers, sports ground curators and lawn care professionals across the country. For homeowners, it represents the same level of protection in an easy-to-apply granular format.
Acelepryn GR controls the full range of turf-damaging insects including armyworm, lawn grubs (African black beetle larvae), billbug, cutworm and mole crickets. Its active ingredient, chlorantraniliprole, works through contact and ingestion with very low mammalian toxicity — making it one of the safest insecticides available relative to its efficacy.
In Perth, armyworm is the primary target. Armyworm populations peak in late summer and autumn (February to April) and can devastate a lawn in a matter of days if not treated promptly. Acelepryn GR provides both curative treatment for active infestations and preventative protection applied ahead of the known risk period.
Apply with a rotary spreader and water in immediately after application. A single application provides season-long protection in most conditions. Compatible with all turf varieties.
Soil Soak Granular Wetting Agent is a long lasting commercial grade non ionic granular wetting agent.
Eco-Prime Emerald is a easy to use fertiliser for your lawn. 20 kg bags.

Autumn Maintenance
Autumn is a very important time of the year for lawn upkeep. Your grass is starting to slow it's growth down to prepare for the cooler months. Now is also the time to start preventing winter weeds and pests. Remove shade sails and prune back trees in preparation for the shorter days and less sunlight. Remember lawn needs at least 4 to 5 hours of sunlight to do well.
HERITAGE MAXX (azoxy) is the only systemic strobilurin that can be taken up by the leaves, crowns and roots of turf plants. The combination of xylem mobility, translaminar movement and even distribution within plant tissue, ensures that new growth is protected for up to 28 days. Best used as part of a preventative plan.
Heritage Maxx is a systemic fungicide that moves through the plant's vascular system to provide protection from within, rather than on the leaf surface only. This makes it significantly more effective for persistent or deep-seated fungal infections and for preventative programs where ongoing protection through the wet winter months is required.
The active ingredient azoxystrobin is a broad-spectrum fungicide effective against a wide range of turf pathogens including take-all root rot, brown patch, dollar spot, grey leaf spot and anthracnose. Take-all root rot is a particularly destructive disease in Perth — it attacks the root system rather than the leaf, causing sections of lawn to collapse without visible above-ground symptoms until damage is severe. Heritage Maxx is one of the most effective treatments available.
Use Heritage Maxx as part of a disease management program rather than as a one-off response. Apply preventatively before the wet season begins, or at the first sign of symptoms. Rotate with Chlortan 720 (a contact fungicide) to prevent resistance development.
Compatible with all turf varieties. Suitable for residential and commercial applications.
OxaFert is one of the most practical and popular products we stock for Perth lawns — a granular pre-emergent herbicide and fertiliser combined in a single application. Instead of applying a separate pre-emergent and fertiliser, OxaFert does both jobs at once, saving time and reducing the number of products needed.
The pre-emergent component creates a chemical barrier in the top layer of soil that prevents germinating weed seeds from establishing a root system. It is effective against the most common winter weeds in Perth — wintergrass, crowsfoot grass and oxalis. Timing is critical: OxaFert must be applied before weed seeds germinate to be effective. In Perth, the target window is May to early June, before soil temperatures drop consistently below 15°C.
The fertiliser component provides a balanced nutrient feed at the same time, supporting colour and root health through the transition into the cooler months.
Apply with a rotary spreader at the recommended rate, then water in immediately. Do not apply to dry soil without watering in — the pre-emergent must be activated by moisture to form the soil barrier.
Compatible with Sir Walter Buffalo, TifTuf, Zoysia Australis and Nullarbor Couch. Check label for application rates specific to your variety.
Plant Growth Regulator (PGR) - controls the rate of vertical growth, whilst increasing lateral growth. Results: less mowing and thicker lusher lawn.
