How to water a rose

How to water roses

Proper watering is crucial for English roses, particularly during the heat of summer. Aim for deep, infrequent watering rather than shallow, frequent watering to ensure your roses receive the right amount of hydration. This approach encourages the roots to grow deeper, enhancing the plant's drought resistance. Watering early in the morning is recommended, as it allows the foliage to dry out by evening, reducing the risk of fungal diseases. Additionally, direct water at the base of the plant to keep the leaves dry, as wet foliage can lead to problems such as powdery mildew. 

How much water?

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 

Newly planted roses should be watered every 3-4 days, whereas established roses should be watered once a week. However, if you see that the roses are showing signs of stress, such as wilting, water more frequently.  

When to water roses

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

We suggest the following:

OCTOBER - FEBRUARY

You are unlikely to need to water roses.

MARCH - MAY

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.

JUNE - SEPTEMBER

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

What you need to water roses

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.
