Common Rose Care Questions Answered

Q: My rose’s leaves are being destroyed, but I can’t find any pests. What should I do?

If you notice holes or damage to your rose leaves without seeing any apparent pests, you’re likely dealing with rose slugs. Although they are called slugs, these pests are the larvae of sawflies and resemble tiny, lime-green caterpillars. Here’s how you can control them:

• Apply a Systemic Insecticide: Start with a soil drench at the base of the plant. This targets pests from the root up.
• Use Insecticidal Soap or Horticultural Oil: Spray the underside of the leaves where these larvae tend to hide and feed.
• Rinse with Water: A strong stream of water can dislodge the pests and help reduce their population.

With consistent treatment, you can manage rose slugs effectively. While the damaged leaves may look unattractive, the roses typically continue to bloom well. After the first flush of blooms, deadhead your roses and feed them to encourage new growth.

How to Identify and Treat Rose Rosette Disease

Q: How can I treat rose rosette disease in my garden?

Rose rosette disease is a severe viral infection affecting many rose plants. It is crucial to identify this disease early to prevent its spread. Here’s what you need to know:

• Recognize the Symptoms: Look for unusual growth patterns, such as excessive thorniness, distorted leaves, and bright red new growth. Be careful, as these symptoms can resemble other common issues.
• Remove Infected Plants Promptly: If you confirm your plant has rose rosette disease, pull it out immediately to prevent the mites from spreading the virus to other roses. Then, dispose of the plant properly.
• Consider Replanting: You can replant roses in the same spot, but be aware that mites may still exist there. Choose resistant varieties and monitor them closely.

Fortunately, studies show that the virus does not spread through tools or clothing, so you can safely continue working in your garden without fear of transmitting the disease.

How to Deal with Holes in Rose Leaves

Q: What’s causing holes in my rose leaves, and how can I stop it?

If you notice small holes and see green caterpillar-like pests on the underside of your rose leaves, you are likely dealing with leaf-eating pests such as rose slugs. Here’s how to address this issue effectively:

• Apply a Soil Drench with Imidacloprid: This systemic insecticide helps control the pests at the root level, preventing further damage.
• Spray with Insecticidal Soap or Horticultural Oil: Focus on the undersides of the leaves where the pests are feeding.
• Rinse with Water: Regularly hosing off the plant can help dislodge the larvae and reduce pest numbers.

Remember, it’s essential to be vigilant because these pests can have multiple generations throughout the growing season.
