Roses are woody plants from the genus Rosa in the Rosaceae family. Most Rose varieties are native to Asia, with smaller numbers being innate to North America, Europe, and Northwest Africa.
Several Rose varieties are grown for their gorgeous flowers, which vary in shades of white, yellow, pink, dark crimson, and maroon. Most have a lovely scent, which differs according to the diversity and climatic settings.
If your favorite Rose plant has started to wilt, this article has all the information you need.
What Causes Roses to Wilt?
Some of the primary causes behind wilting of Roses are watering problems, transplant shock, and temperature changes. However, certain pests like aphids can also cause wilting of your Rose plant. Diseases like verticillium wilt and stem canker will also impact the plant’s health leading to a wilted appearance.
The Top Reasons Why Your Rose May be Wilting
Watering your plant the right way is extremely important for healthy growth. Water is crucial for the transport of nutrients in the plant. Hence, without proper watering, your Rose will wilt or even dry and wither.
Roses that do not obtain sufficient water often wilt, grow stunted leaves, have flowering troubles, and drop their leaves.
The bushes of Rose need at least 1 inch (2.5 cm) of water every week. During the hot summer season, it is essential to water it more.
When your Rose plant has fully developed, watering it once or twice a week is just fine. The Rose plant has a deep root system, so it is essential to water it carefully, so the water gets deep in the soil.
Roses can also wilt and droop when you overwater them or when the pot does not have proper drainage holes.
When the water does not drain out, the plant’s soil remains soggy, and this causes problems for your plant.
An overwatered Rose bush will turn yellow and start to droop. Excessive water will be unsafe for your plant as it will deprive the roots of oxygen and even leads to diseases.
If you notice that the recently repotted or transferred Rose plant is droopy and limp, transplant shock could be the reason behind the wilting.
This is because the roots cannot take the water and nutrients, or the Rose plant got damaged during the process.
The ideal temperature for Roses is 80 degrees Fahrenheit (27 degrees Celsius), with a relative humidity of 60-70%.
It is recommended to water your Rose plant more when the temperature is high. Especially the Rose plants growing outdoors else they will wilt and die.
Similarly, a very cold season is not good news for your stunning Rose plant. These plants struggle a lot during the winter season. Roses are unable to withstand temperatures below 32 degrees Fahrenheit (0 degrees Celsius).
As mentioned above, they want a good warm environment to thrive. Therefore, if no proper care is taken during the winter season, the plant starts dropping leaves and eventually wilts.
Pests and Diseases
Some certain pests and diseases will cause wilting on different Rose varieties. It will be helpful if you keep an eye on these and, if infested, treat them right away.
Aphids are pests that try to find out Rose plants as hosts. Aphid damage results in wilted, curled leaves, stunted growth, and flowering problems.
Rose aphids, specifically, target Roses and exhibit pink or green forms and black legs.
They feed on leaves, stems, and flowers by extracting plant tissue juices. As aphids consume, they emit honeydew, a sticky, sugary material that drops onto various parts of the plant.
Stem Canker Disease
Stem canker disease is a fungal disease that disturbs Roses, causing the growth of cankers or scratches. As the stem gets infected and dies because of the canker formation, leaves start to wilt.
Home gardeners should watch out for egg-shaped cankers exhibiting a brown color that create hollows within plant tissue.
Verticillium Wilt Disease
Verticillium wilt of Roses is a fungal virus that causes the wilting of stems and the yellowing of leaves that are close to the ground.
Wilting is often permanent when no treatment is given, and this disease can even lead to leaf drop or plant death.
Solutions to Keep Your Rose Safe from Wilting
There are a few suggestions that will help you prevent the wilting of this astonishing plant. It is vital to follow these to have a healthy plant.
Roses need steady irrigation through the developing period for healthy growth. It is recommended to water more in the warm-season as water evaporates quickly.
During the cold winter season, it will be absolutely fine to water it less. This is because when you water your Rose, the extra water will take longer to dry. Hence it will get the right amount of water without any problems.
Prevention of Transfer Shock
To keep your plant safe from transplant shock, it is highly recommended to transplant when your plant is about to start growing actively.
Before you plant your Rose bush in a new place, give it a thorough wash with water. This will allow the plant to store the water that can be used during the transplant procedure.
Rose plants prefer a warm climate for healthy growth. An ideal temperature for Roses to grow is 80 degrees Fahrenheit (27 degrees Celsius).
During the warm summer season, it enjoys a temperature of around 94.46 degrees Fahrenheit (34.7 degrees Celsius). You should also avoid keeping it in the cold regions (temperature falling below 32 degrees Fahrenheit or 0 degrees Celsius) for a very long period.
Treating Pests and Diseases
Releasing beneficiary insects that hunt and kill aphids is a good option to control pests in outdoor gardens. You can buy ladybugs or parasitic wasps from garden supply shops.
If the infestation is heavy, I would recommend using horticulture oils.
There is no chemical to control the stem canker. You can stop this disease by keeping the Roses free from stress. Another solution can be to prune the cankers.
To prevent verticillium wilt, avoid planting your Roses in old vegetable gardens. Remove and destroy symptomatic or dead branches, preferably before leaves fall.
Also, always disinfect your pruning tools as they are the one major cause of this disease transplant.
