May is “Superbowl” month for roses! In order to have the biggest impact in your landscape your roses need to be healthy. As we dive into the blooming season, it’s crucial to keep an eye out for potential threats to our beloved roses. One common problem that can wreak havoc on your precious blooms is Rose Rosette Disease. Learning how to care for roses with rose rosette can help keep your plants healthy and happy so they can show off this season!
What is Rose Rosette Disease?
Rose Rosette Disease is caused by a virus known as Rose Rosette Virus (RRV), transmitted by microscopic mites. It primarily affects shrub roses (Rosa multiflora and its hybrids), resulting in distorted growth, excessive thorniness, and an abundance of red or pink shoots called “witches’ brooms.” If left unchecked, it can lead to the death of the entire plant.
How to Identify Rose Rosette Disease
Early detection is key to combating Rose Rosette Disease. Keep a vigilant eye out for the following symptoms:
- Witches’ Brooms: Look for clusters of small, deformed shoots growing from a single point.
- Red or Pink Discoloration: Check for unusual red or pink coloration on leaves, stems, or buds.
- Excessive Thorns: Notice an abnormal increase in thorniness on stems and branches.
- Stunted Growth: Observe if the plant is failing to grow or producing smaller-than-usual leaves and flowers.
What to Do If You Find Rose Rosette Disease
If you suspect your roses are infected with Rose Rosette Disease, take swift action:
- Isolate the Plant: Immediately isolate the infected plant to prevent the spread of the virus to healthy roses.
- Prune Infected Parts: Prune out and dispose of infected stems and branches in a black trash bag (No Compost for these), make sure to sanitize pruning tools between cuts. If multiple branches are infected it is best to quickly remove and replace the entire plant and treat all around it with preventative insecticides.
- Use an Insecticide: Choose an insecticide that names Mites in the effectiveness list
- Monitor Other Roses: Keep a close watch on nearby roses for any signs of infection, and take preventive measures promptly.
Preventing Rose Rosette Disease
Prevention is the best defense against Rose Rosette Disease. Here’s what you can do:
- Choose Resistant Varieties: Opt for rose varieties that are less susceptible to the disease, such as Knock Out roses.
- Maintain Good Garden Hygiene: Keep your garden clean and tidy, removing debris and fallen leaves where mites may hide.
- Control Mite Populations: Regularly spray your roses with horticultural oils or insecticidal soaps to deter mites.
- Plant with Space: Plant roses with ample spacing between them to minimize the risk of disease transmission.
