spider mites on Rose
Quick answer
If your Rose has spider mites, the most likely cause is: Tetranychus urticae thrive in hot, dry, dusty conditions. They pierce plant cells and suck out contents, causing leaves to look dull, stippled (tiny yellow/white dots), and eventually turn bronze or yellow and drop. Fine webbing is often visible.
Start here:
- 1. Hose down the bush with a strong blast of water every 2-3 days to disrupt their life cycle and raise local humidity
- 2. Apply horticultural oil or insecticidal soap, completely coating the undersides of leaves
