How to Water Roses in Australia
When the warm weather arrives, it's essential to keep your roses well-hydrated. Our guide to watering roses will help you keep them healthy and blooming throughout the hotter months. The amount of water needed and how often you should water depends on specific weather conditions and soil type.
As a guide, we recommend watering the following amount per rose each time you water:
- Shrub roses – 5 litres
- Climbing roses – 10 litres
- Rambling roses – 10 litres
- Standard tree roses – 10 litres
- Roses in pots – 5 litres
When to Water Roses
Watering needs vary throughout the year, depending on rainfall and seasonal temperatures.APRIL - SEPTEMBER
(Cooler months) In most regions of Australia, you are unlikely to need to water roses frequently unless experiencing an unusually dry spell.OCTOBER - DECEMBER
(Spring to Early Summer) Watch for prolonged dry spells of two weeks or more, particularly if the weather is warm. Water newly planted roses every two to three days and established roses once a week.JANUARY - MARCH
(Peak Summer Heat) Water newly planted roses every other day and established roses once a week. If your rose starts blooming, check for wilting flowers. This can happen in extreme heat and is a reliable sign that your roses need more water.Situations That May Require Extra Attention:
- Newly planted roses
- Climbing roses planted against walls, where soil is drier
- Roses planted in sandy or fast-draining soil
- Roses grown in pots or containers
What You Need to Water Roses
The best way to water is with a watering can so you can measure the amount used. If you have many roses, a hose with a rose attachment is more practical.Tip 1: Water at the Base of the Rose
Water as close to the base of the rose as possible. If the water starts to run off, pause to let it soak in before continuing.
Tip 2: Avoid Flowers and Foliage
Avoid watering over the flowers or leaves, as this can encourage fungal diseases, particularly if moisture remains on the foliage overnight.
Tip 3: Use a Gentle Spray
We recommend a soft spray rather than a high-pressure jet or deluge from a hose. If using a hose, choose a fitting with a rose setting or adjust the pressure to a gentle flow.
By following these guidelines, you’ll help ensure your roses thrive throughout the Australian seasons.
