Roses are some of the most popular and widely cultivated flowers in the world. These beautiful flowers come in several colors and symbolize affection, love, innocence, joy, and purity. But to produce their best flowers, roses need to be watered correctly. In this article, we’ll find out when and how to water roses.
When and How to Water Roses – 10 Essential Tips to Follow:
- Water roses deeply but infrequently. This may mean watering once a week during spring and summer to keep the soil moist.
- The best time to water roses is in the morning, which helps ensure the leaves have time to dry out during the day, reducing the risk of diseases like blackspot and powdery mildew.
- Avoid watering roses from above, as this can splash soil onto the leaves, potentially spreading diseases. It can also lead to sunburn if the water droplets on the leaves magnify the sun’s rays.
- Soaker hoses or drip Irrigation are often the best options for watering roses because they deliver water directly to the roots and help keep the foliage dry. They’re also more water-efficient.
- It’s important to check soil moisture before watering. Stick your finger into the soil, if the top 2 inches feel dry, it’s time to water. If it feels moist, wait a day or two.
- Mulching helps retain soil moisture and keeps the roots cooler, reducing the plant’s water requirements. Use organic mulches like compost, well-rotted manure, or wood chips.
- When you water, do it deeply to encourage roots to grow down, which helps the plant withstand drought better. A good rule of thumb is to water until the top 5 or so inches of soil is moist.
- In hot, dry, or windy weather, roses will need more frequent watering. After heavy rain, you may not need to water for several days.
- Newly planted roses have shallower roots and may need to be watered more often, typically every 2-3 days. Gradually increase the time between waterings to encourage deeper rooting.
- Roses grown in containers or pots will need more frequent watering, often daily in hot weather, because pots dry out more quickly than the ground.
The Importance of Watering Correctly
Like most organisms on Earth, plants depend on water to survive. Plants absorb water from the surrounding soil using their roots. Water helps plants create healthy new stems, leaves, and flowers – forming up to 95% of a plant’s total mass.
Along with carbon dioxide and sunlight, water is extremely vital for photosynthesis. While water is absorbed by the roots, carbon dioxide, and sunlight are absorbed through the leaves. Combining these resources produces glucose, a vital sugar used to manufacture cellulose – the basic building block of plant tissue.
When plants absorb water from the soil through their roots, they also take in important nutrients and minerals. These vital nutrients include nitrogen, phosphorus, and potassium. Nitrogen helps produce bushy foliage, while phosphorus is essential for flower development.
Plants also use water to cool themselves down in hot conditions. Using a process called transpiration, plants allow excess water to evaporate through their leaves. This reduces temperature but also stimulates the plant to absorb fresh water from the soil.

How Often Do Roses Typically Need to be Watered?
Established roses typically need to be watered about once a week. Most roses need a full can of water each week to keep the soil nice and moist. During the summer, most roses should be watered every three or four days if the weather is hot and dry. Water your roses early in the morning to prevent too much water from evaporating before it reaches the roots.
I like to water my newly-planted roses every two or three days, especially during the summer. This helps my roses establish a sound root system without suffering from stress. Roses growing in pots need watering more frequently than those growing in the ground.
Do Roses Prefer Wet or Dry Soil?
Roses prefer rich, well-draining soils that still retain some moisture. As such, roses prefer moist soils rather than dry or waterlogged soils. If the soil gets too dry, your roses will struggle to produce good flowers. If the soil is too wet, your roses could suffer from fungal infections and root rot.
How Do You Know When a Rose Plant Needs to be Watered?
Many roses will start drooping or wilting when they need a drink. Keep an eye on the flowers and water your rose if the blooms start wilting in summer. Check the soil regularly and water your roses if it feels too dry.
How to Check if Your Rose Plant Needs Watering
To check if your rose needs watering, examine the flowers and stems to see if they’re wilting. You can also check whether the soil still feels moist using your finger. Push your finger into the soil and water your roses if your finger feels almost completely dry.
Environmental Factors That Influence Watering Cycles
Hot temperatures, low humidity, and more sunlight are all factors that force roses to use more water. In these conditions, roses often need to cool themselves down through transpiration. As such, you’ll need to water them more frequently to replace the lost water.
Roses are generally happiest in USDA Zones 4 to 10 and grow best in temperatures between 60 and 70ºF. While most roses can tolerate hot temperatures up to 100ºF, this causes them to use more water.
In cooler temperatures or areas with higher humidity, roses will use less water. Therefore it’s important not to overwater your roses in these conditions.
Seasonal Factors That Influence Watering Cycles
Roses use water differently in different seasons, which affects how you should water them throughout the year. During the summer, roses use more water as conditions get hotter and drier. Water your roses every three or four days in exceptionally hot or dry conditions.
During the winter, many roses lose their leaves and go dormant. As such, you can cut back on watering them. Water your roses deeply after the first frost and apply a thick layer of mulch to preserve moisture. Water them sporadically but don’t let them fully dry out.
How to Water Roses
Watering roses correctly protects your plants from diseases and enables them to use water as efficiently as possible. Roses prefer to be watered deeply and allowed to dry out slightly. However, take care to avoid overwatering or underwatering your roses.
Use a rose attachment on your watering can to reduce the risk of overwatering. Aim your watering can around the base of the rose and thoroughly soak the soil. Avoid splashing water onto the leaves or flowers, as this can lead to rot and other problems.
Signs That You Might Be Overwatering Your Roses
Drooping or Wilting Leaves
If your roses have drooping or wilting leaves, you might be overwatering them. Drooping or wilting leaves are one of the symptoms of root rot, which is caused by waterlogged soil. Improve soil drainage by adding some fine grit, perlite, or sand, allowing your rose to dry out more.
Yellowing Leaves
Yellowing leaves are another sign that you might be overwatering your roses. In my experience, this is also a common symptom of root rot. Remove any yellowing leaves and check the soil. If it feels too wet, add sand or grit to improve drainage and wait for the soil to dry out.
Waterlogged Soil
If the soil around your rose stays waterlogged for several days, you may be overwatering your roses. Roses prefer moist soils rather than wet soils. Waterlogged soil indicates that the soil isn’t draining correctly, so mix in some grit, sand, or perlite.
Signs That You May Be Underwatering Your Roses
Wilting Flowers or Leaves
You may be underwatering your rose if your rose’s leaves or flowers are wilting. Check the soil and water it gradually over a couple of days if it feels really dry. This rehydrates the soil and should help your rose to perk up.
Dry, Cracked Soil
If the soil around your rose is dry and cracked, you’ve probably been underwatering your rose. Re-hydrate the soil by watering it gradually over the next couple of days. Add in some more organic matter, such as compost to improve water retention.
About Roses
Roses are woody perennial shrubs from the Rosa genus of the Rosaceae family. Many of these gorgeous flowers are native to China and other parts of Asia and North America. Hundreds of hybrids and cultivars are also available.
There are three main types of roses; old garden roses, species roses, and modern or hybrid roses. These main groups are further divided into various sub-groups such as Floribunda roses and Polyantha roses.
Roses have stout, woody stems laden with distinctive thorns. Most roses are deciduous and have alternate oval-shaped leaves with serrated margins. Roses are famous for their large, fragrant flowers with five petals. The flowers are then followed by red berries known as rosehips.
