Several factors may contribute to the appearance of holes in rose leaves. Understanding these causes is pivotal for effective intervention and revitalizing the roses:

  1. Weather Events: Hailstorms can leave a visible impact on rose leaves, causing holes and disrupting their smooth surface. Similarly, strong winds on particularly gusty days may lead to leaves colliding with branches, resulting in perforations.
  2. Insect Infestation: If the damage cannot be attributed to weather conditions, it’s likely that insects are the culprits. During the summer, insects and parasites proliferate not only in outdoor spaces but also inside homes. Identifying and addressing insect infestations promptly is crucial.

To combat infestations effectively, especially those caused by black sawflies or argids (rose caterpillars), targeted actions can be taken:

  • Black Sawflies: If black sawflies and their larvae are identified on the undersides of leaves, periodic monitoring is essential. Treatment options include using a damp cloth or a pyrethrum-based product, effectively eliminating black sawflies.
  • Argids (Rose Caterpillars): During the summer, rose plants may face challenges from argids. Regular health checks are advised to prevent irreversible damage. Chemical products can eliminate argids, with a preference for pyrethrum-based treatments. Alternatively, a natural remedy involves mixing 15 grains of finely minced black pepper in half a liter of water. Let the solution rest for an hour and then spray it on the leaves to eliminate argids and restore the rose plant to optimal health.

In conclusion, vigilance and prompt action are paramount when addressing holes in rose leaves. By understanding the potential causes and employing targeted interventions, enthusiasts can ensure the longevity and well-being of their cherished rose plants.
