Troubleshooting
Burgundy Glow Bugle problems — and how to fix them
Burgundy Glow Bugle (Ajuga reptans 'Burgundy Glow') 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.
Crown rot
More susceptible to crown rot than plain-leaved Ajuga forms, particularly in heavy, poorly drained soils or during warm, wet summers. Ensure excellent drainage, avoid overhead watering, thin mats to improve airflow, and remove affected rosettes immediately. In problem areas, consider raising beds slightly or switching to a more rot-resistant groundcover.
Loss of tricolour variegation
Plants in deep shade or those that have reverted may produce predominantly dark-green rosettes, losing the silver and pink tones. Remove plain green reverted rosettes at the base immediately. Reposition to brighter indirect or morning-sun light to restore the full tricolour effect.
Powdery mildew
White powdery coating may develop on leaves in warm, dry weather or where air circulation is poor. Thin overcrowded mats, remove affected foliage, and apply neem oil or a bicarbonate-based spray at first signs. Ensure the site has some air movement to reduce recurrence.
