Troubleshooting
Bacopa problems — and how to fix them
Bacopa (Sutera cordata) 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.
Summer heat stress and flower drop
Bacopa is a cool-season plant and typically stops flowering or drops buds when temperatures exceed 30°C. Move containers to a shadier, cooler position, reduce feeding, and water consistently. Flowering resumes strongly as temperatures cool in early autumn.
Powdery mildew
White powdery coating appears on leaves in humid, crowded conditions. Improve airflow around plants, avoid wetting foliage in the evening, and apply a bicarbonate of potassium or sulphur spray at first detection.
Wilting and drying out
Shallow, fibrous roots dry out very rapidly in small or terracotta containers on hot days. Check moisture daily in summer. Adding water-retaining gel crystals to the potting mix or switching to glazed ceramic containers reduces desiccation risk.
Prevent bacopa problems before they start
Most bacopa issues are care-mismatch, not bad luck. Dial in the basics:
