Powdery Mildew

This is a common fungal disease in roses, caused by pathogens like Podosphaera pannosa. It manifests as a white, flour-like coating on leaves and buds, often triggered by high humidity and poor air circulation around the compact Rosa Terrazza foliage.

Very Common

1 Apply an organic fungicide to eliminate the existing fungal spores and prevent the spread to healthy foliage.
2 Improve air circulation around the compact foliage and avoid overhead watering to reduce the high humidity that triggers mildew.
3 Prune and dispose of heavily infected leaves to prevent the pathogen from spreading to new buds.

Mealybugs

These small, soft-bodied insects secrete a white, waxy, cottony substance to protect themselves. On mini roses, they tend to cluster in the crevices between leaf nodes and near the base of the stems.

Common

How to confirm: Look for tiny, slow-moving insects hidden in the leaf axils or under the foliage.

1 Isolate the plant immediately to prevent the mealybugs from spreading to other greenery and use a cotton swab dipped in isopropyl alcohol to manually remove visible white waxy clusters.
2 Apply an organic insecticide spray to the entire plant, ensuring you coat the crevices of leaf nodes and stem bases where pests hide.
3 Monitor the plant regularly with a spray bottle to maintain humidity, which can help prevent further pest outbreaks, and check for new infestations.
warning

Scale Insects (Cottonyy Scale)

Certain species of scale produce a white, powdery or waxy secretion as they feed on the plant's sap. This can cause the Golden Terrazza leaves to become sticky (honeydew) and eventually yellowed.

Common

How to confirm: Check for small, hard bumps on the stems that are covered in a white, powdery residue.
