Troubleshooting
Axillary Balm problems — and how to fix them
Axillary Balm (Melissa axillaris) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
Humid, still conditions encourage this fungal disease. Improve air circulation, avoid overhead watering, and remove affected leaves promptly. A dilute potassium bicarbonate spray can help manage outbreaks.
Root rot
Caused by overwatering or poorly draining soil. Ensure the pot or bed has adequate drainage, and allow the top layer of soil to dry slightly between waterings. Affected plants may wilt despite moist soil — check roots for brown, mushy tissue.
Aphids
Clusters of soft-bodied insects on new growth and flower buds are common in spring. Dislodge with a strong water spray or apply neem oil solution. Natural predators such as ladybirds help keep populations in check outdoors.
