scale insects on Myrtus Communis
Quick answer
If your Myrtus Communis has scale insects, the most likely cause is: Indoor Myrtus communis bonsai are explicitly listed as susceptible to scale insects in two independent Brooklyn Botanic Garden handbooks, where the small scale settles on the evergreen leathery myrtle foliage and on the young stems and quietly sucks sap, weakening the Mediterranean shrub over time.
Start here:
- 1. Inspect the leathery myrtle leaves and stems at every watering for the small bumps of scale, then spray with an appropriate insecticide following the directions on the label to bring an active scale infestation under control.
- 2. Improve light and air circulation through the dense inner canopy of the indoor myrtle bonsai so the still, humid pockets that scale insects favor do not build up on shaded interior growth.
