How to water roses

Watering is key to keeping your English roses healthy, especially during the heat of summer. Instead of frequent, shallow watering, opt for deep, infrequent watering. This encourages the roots to grow deeper, making your roses more drought-resistant. The best time to water is early in the morning, which allows the foliage to dry out by evening, reducing the risk of fungal diseases. Always aim to water directly at the base of the plant to keep the leaves dry, minimising issues like powdery mildew.

As a general guide, here's how much water to give each rose:

Shrub roses – 1.5 gallons 

Climbing roses – 2.5 gallons 

Rambling roses – 2.5 gallons 

Standard tree roses – 2.5 gallons 

Roses in pots – 1.5 gallons 

Newly planted roses should be watered every 3-4 days, while established roses can be watered once a week. However, increase the watering frequency if your roses show signs of stress, like wilting. 

The need for watering varies greatly throughout the year and is directly related to the amount of rain that has fallen.

During the winter months it is unlikely that you will need to water your roses. As spring approaches watch out for particularly prolonged dry spells of two weeks or more, particularly if the weather is warm. Water newly planted roses every two or three days and established roses once a week.

During the summer months water newly planted roses every other day and established roses once a week. As your rose starts blooming, take note if your flowers are wilting. This will happen in extreme heat but is a reliable sign that your roses need more water.

SITUATIONS THAT MAY REQUIRE EXTRA ATTENTION:

  • Newly planted roses
  • Climbing Roses planted against walls due to the dry nature of the soil in that location
  • Roses planted in sandy soil
  • Roses planted in a pot or container

The best way to water is with a watering can, so that you can see how much water you are using. If you have a lot of roses, then a hose with a rose attachment is more practical.

TIP 1

Water at the base of the rose

It is best to water as close to base of the rose as you can. If the water is starting to flow away from the base, stop for a moment to allow the water to soak in, then continue.

TIP 2

Avoid flowers and foliage

Don’t water over the flowers or foliage. Watering foliage can encourage disease problems, particularly if it remains on the leaves overnight.

TIP 3

Use a softer spray

We recommend a softer spray rather than a fierce deluge from a jet spray or pressure hose. If using a hose, try to get a fitting that has a rose setting. If you haven’t got a special fitting, make sure the pressure is not too high on your hose.
