But drought was not the only cause of tree decline, and the council responses reported in May 2024 should not be read as a current or uniform watering policy.
What the rainfall record and council survey showed
PerthNow reported that Perth received 21.8 millimetres of rain from October 2023 through March 2024, its driest October–March period on record at the time. Of 16 metropolitan councils contacted for the 2 May 2024 report, 13 said they had systems to monitor trees and provide extra water when needed. That was a snapshot of the councils surveyed, not a complete census of current practice.
A later figure describes a different period: the Botanic Gardens and Parks Authority recorded 16.6 millimetres from November 2024 through February 2025, approximately 20 per cent of the 10-year average for those months. The periods are not directly comparable. Its 2024–25 annual report also says reduced rainfall and higher temperatures contributed to continued loss of bushland trees and shrubs and limited canopy recovery after the 2023–24 drought.

#1 Best Overall
- 【BIG CAPACITY】Holds up to 20 gallons of water for deep watering to keep trees hydrated longer, especially in drought or hot weather areas. Most bags typically empty within 5–9 hours, while actual watering time may vary depending on soil type, weather, tree size, and water pressure. In some cases, it may take 5–24 hours to fully empty. Based on our testing, this release rate helps water reach the roots effectively while reducing evaporation in hot or dry conditions.
- 【EASY TO USE】Very easy to use, just wrap this water bag around the trunk, tighten the zipper and pour water in it. For larger trees, you can pull two of these drip irrigations together.
- 【HEAVY DUTY MATERIAL】Made of durable PVC tarpaulin material, UV resistant. Designed with wide water fill hole suitable for universal size hose, and sturdy handle for long time use.
- 【TIMELY HYDRATION】Our carefully tested watering system efficiently nourishes trees, saving you time and water. It guarantees water reaches the roots, preventing waste and evaporation, especially important during hot summers or droughts. Plus, It reduces the risk of waterlogging and root rot for too slow release. These are essential for newly planted or transplanted trees growth.

| Approach | Reported examples |
|---|---|
| Routine watering for young trees | Victoria Park said newly planted trees were watered once or twice a week during warmer months for their first three years, depending on rainfall. Mayor Karen Vernon described this as the council’s practice, not a general prescription. |
| Extra water for established trees | South Perth reported supplementary watering for mature trees showing stress. Stirling said some drought-stressed mature trees were watered fortnightly. Victoria Park trialled heavier watering for about 40 mature trees most affected by low rainfall. |
| Earlier or extended seasonal watering | Nedlands and Fremantle planned to start watering earlier and continue later into autumn. |
| Observation, monitoring and reporting | Joondalup said staff could increase watering after visual observations or soil-moisture readings indicated heat stress. Vincent reported water-truck watering and community reporting. |
| Water with other treatments | Wanneroo, Belmont and Bayswater paired extra water with soil wetters and fertiliser; Canning reported water, nutrients and mulch. |
Not every council increased watering. One said it had not increased its schedule, while Melville said water and labour limits made regular watering of every established street tree impractical. Stirling Mayor Mark Irwin also cautioned that the cause of removals could not be counted precisely: “It is not possible to know precisely how many have died due to a lack of water but given increased temperatures, that is likely a factor.”
Why drought does not explain every declining tree
Councils also named pests and disease. Vincent cited losses associated with polyphagous shot-hole borer (PSHB), while Cottesloe described Neofusicoccum parvum affecting established Norfolk Island pines. A stressed or dying tree may have more than one contributing cause; the 2024 council reports do not establish a Perth-wide count of trees killed specifically by drought.

- Durable Material: These automatic tree drip irrigation bags are made of premium PE material and surface of these drip irrigation bags is sunlight-proof, so they are resistant to aging so you can keep them for a long time for not one-season use.
- Easy To Use: First, you need to place a tree watering bag around the bottom of the trunk, then tighten the zipper on the drip irrigation bag, finally you can put the water pipe into the water injection port at the top of the bag and fill the tree watering bag with water.
- Efficiently Work: These tree drip irrigation bags are all with a large capacity fo 20 gallon, and after you install these irrigation bag and fill them with water, the water in the bag body will slowly release and penetrate into the soil and trunk within 4-5 hours to keep the roots of the saplings moist.
- Of Great Benefits: These tree drip irrigation bags can save more than 30% of water than traditional irrigation methods, they are also very adaptable and do not pick soil, at the same time, they save lobor and can be used with nutrient solutions to improve the quality of tree growth.
Pest control is a separate response. In a statement dated 18 March 2026, the City of Perth said two of its trees were removed because of PSHB in 2024–25 and reported an approximately 95 per cent beetle reduction following bifenthrin treatment at identified locations. These are outcomes reported by the City for its own PSHB program, not a metro-wide drought measure. City of Perth: PSHB urban forest response

State canopy target and greening actions
The WA Urban Greening Strategy sets a target to raise tree canopy in Whadjuk (Perth) and Bindjareb (Peel) to 30 per cent by 2040. Its action plan includes planting one million trees by 2035, grants and a Treebate incentive, and promotes locally suitable native species and waterwise practice. These are targets and program commitments, not evidence that the targets have already been met. Government of Western Australia: Urban Greening Strategy

The WA Tree Recovery Local Government Grant Program supports replacement planting for trees affected by PSHB and a more diverse future canopy. The program page says its 2026 second round awarded more than $3.3 million to 26 local governments to support more than 10,000 trees. Awards and application periods can change; consult the official program page for current details and recipients.
Climate-ready street-tree trials
In a 29 September 2026 update, the City of South Perth said five species in its participation in WALGA’s six-year Climate Ready Street Tree Trials showed healthy growth at a nine-month check. Named species included Jingymia Mallee, Lemon-flowered Gum, Silver Gimlet and Strickland’s Gum. The trial tracks survival, health and longer-term performance; an early check is not a final ranking or proof of long-term drought resilience. City of South Perth: climate-ready street-tree trial

What residents can take from the reports
- Visible decline is a reason to report a tree to the responsible local council, but not proof that drought is the cause. Councils reported using observation, soil-moisture readings and community reports in different ways.
- Do not assume a watering schedule used by one council is suitable for another tree, street or season. The reported practices varied, and Melville described limits on water and labour.
- For construction or landscaping near established trees, avoid treating drought as the sole risk: the reports also identify pest and disease pressures, while state planning emphasizes locally suitable species and waterwise practice.
