Heavy rainfall across large parts of eastern Australia over recent weeks may have disrupted weekend gardening plans, but the long-term benefits for lawns, gardens and landscapes are significant heading into winter.
“The widespread soaking rain has delivered one of the most important ingredients for healthy winter growth — deep sub-soil moisture,” said COX CEO Steve Wright.
“While waterlogged lawns and muddy gardens can be frustrating in the short term, this type of prolonged rain event is incredibly valuable for soil health,” he said.
“Unlike short summer storms that often run off quickly, steady rainfall allows moisture to penetrate deep into the soil profile, where plant roots can access it over the cooler months ahead,” he continued.
For lawns, particularly across regional and suburban Australia, the rain arrived at an ideal time before winter dormancy begins slowing grass growth.
Deep soil moisture helps strengthen root systems, improve resilience and support healthier spring recovery later in the year.

Gardeners are now being encouraged to adjust their lawn and garden maintenance routines to suit the wetter conditions:
(i) Avoid mowing overly wet lawns, as this can compact soil, damage turf structure and leave unsightly wheel marks. Instead, allow lawns time to partially dry before mowing, and ensure mower blades are sharp to deliver a clean cut rather than tearing damp grass.
(ii) The rain also creates ideal conditions for fungal diseases and weed growth. Garden beds should be checked regularly for signs of mould, mildew or root rot, particularly around heavily mulched areas with poor airflow.
(iii) Now is also an excellent time to aerate compacted lawns, apply light fertiliser treatments where appropriate, and top up mulch around garden beds to help lock in valuable moisture during the cooler months ahead.
(iv) Importantly, gardeners should resist the urge to overwater in coming weeks.
“Many areas have received a substantial moisture reserve beneath the surface,” Steve said. “With cooler temperatures approaching, evaporation rates drop significantly, meaning gardens and lawns will require far less supplementary watering than many people realise.”
As Australia moves into winter, the recent rainfall event will provide the foundation for healthier lawns, stronger gardens and improved growing conditions well into spring.
“Must be almost time to dust off the log splitter!” smiles Steve.
