Water

Regular watering is essential, particularly during hot, dry periods. Keep the soil consistently moist but not waterlogged, and water at the base to avoid wetting the foliage.

Disease and Pest Resistance

Although this heirloom rose is loved for its beauty, it can be prone to:

Pest Resistance

This rose may attract common pests such as aphids, spider mites, scale insects, or caterpillars. These pests can damage foliage, flowers, and stems, reducing the plant’s vigor.

Disease Resistance

Roses are susceptible to several fungal diseases, including rose black spot, rust, and powdery mildew. These diseases often thrive in humid conditions, causing leaf discoloration, defoliation, or stem dieback. Disorders like rose blindness (failure to bloom) and flower balling (petals failing to open) may also occur under certain conditions. In severe cases, honey fungus, a soil-borne pathogen, can damage the plant’s root system.

Prevention and Care

Regular monitoring, proper pruning, and ensuring good air circulation can minimize risks. Applying organic pest control measures and treating fungal infections early with fungicides are essential to maintaining healthy roses.
