Weed spraying needs a licence in WA. The Department of Health's pesticides FAQ (opens in a new tab) answers this exact question for lawn mowing businesses: anyone who charges a fee to manage weeds needs to be licensed under the Health (Pesticides) Regulations 2011, and that applies even to a business that only uses glyphosate. Its list of endorsements includes weed control with hand-held and backpack equipment, and a separate endorsement for pest and weed control with mechanical equipment such as a boom spray. A self-employed technician also has to register the business as a pest management business with the Department, which is separate from an ABN or ASIC registration. If you're licensed, it's worth showing customers; if you're not, the site shouldn't list spraying. The department's licensing team is the place to confirm which endorsement fits your work.
Water rules shape the year. Perth's two-day sprinkler roster and the Waterwise endorsements are covered on our Perth landscapers page. Two parts matter most to a mowing round. Water Corporation lets businesses in the turf, garden and landscaping industry apply 10 mm of water immediately after fertiliser, a wetting agent or vertimowing, an exemption general customers don't get, so a lawn renovation service you sell in spring can include the watering-in. And the winter sprinkler switch-off (opens in a new tab) from 1 June to 31 August covers scheme and bore water users in Perth and Mandurah, so a site that sets out a winter visit plan before customers start asking is worth more than one that just lists a fortnightly price.
Fire hazard notices in the hills. Councils on the urban fringe issue annual notices under the Bush Fires Act 1954, and each sets its own date. The City of Kalamunda's 2026/27 notice asks owners of lots under 5,000 m² to cut unmanaged or dead grass, weeds and plants to no more than 50 mm by 1 November 2026, and keep it that way until 31 March 2027, with firebreaks on larger lots. The City of Armadale's notice gives a 30 November 2026 deadline for flammable material under 5 cm on smaller lots, 3-metre firebreaks on lots over 5,000 m², and penalties of up to $5,000. A slashing and fire-season page that names the councils you work in and their deadlines brings work from owners who won't do it themselves, and a booking cut-off in October helps you plan the rush.
Verges, rentals and shot-hole borer. Many Perth councils leave the verge to the household: the City of Joondalup says general upkeep of verge lawns and gardens is done by the adjoining residents, while it looks after street trees and footpaths. Consumer Protection says tenants must clean the home and any gardens when they move out, which is where end-of-lease tidy-ups for tenants and property managers come from. The Department of Primary Industries and Regional Development now manages polyphagous shot-hole borer under a transition-to-management plan, as eradication is no longer considered feasible, and its quarantine area covers the whole Perth metropolitan area. DPIRD asks gardeners to check pruned trees for signs of the beetle, sanitise tools with 70% ethanol before moving to healthy trees, and carry green waste to council facilities in a sealed and covered trailer, skip or truck. A sentence on your site saying you follow those steps tells customers with large exotic trees that you've thought about it.
How we work with Perth businesses. We're an Adelaide team and build for Perth mowing and garden businesses by phone and email. Adelaide is 1.5 hours ahead of Perth, or 2.5 hours while South Australia is on daylight saving, so we keep that in mind when we call. You send the suburbs you cover, what a visit includes and costs, your winter plan and photos of lawns you look after; we send a draft link you can check between jobs.
