Do Hydrangeas Need a Lot of Water?
Yesโhydrangeas are thirsty plants. Their large leaves and flower heads require steady moisture to stay healthy, especially in Australiaโs hot summers.- Garden Beds: Deep water 2โ3 times per week in warm weather.
- Potted Plants: Check daily in summerโwater whenever the top 2โ3cm of soil feels dry.
- Mulch: Essential for retaining moisture and protecting roots from heat stress.
Hydrangeas will quickly show signs of stress if water is lackingโwilting leaves by midday is a common indicator.


How to Water Hydrangeas
Hydrangeas donโt like dry spells, but they also dislike soggy soil. Consistent, deep watering is best.
- Deep Soaks: Water at the base to reach roots, rather than light sprinkling.
- Morning Watering: Best time to water, reducing evaporation and disease risk.
- Pots: Use saucers sparingly. Empty excess water to avoid root rot.
- Seasonal Adjustments: Water more often in summer, less in winter dormancy.
Always water before applying fertiliser. This protects roots and helps nutrients from CompleteGrow fertilisers absorb effectively.
