Troubleshooting
White laceflower problems — and how to fix them
White laceflower (Orlaya grandiflora) 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.
Root rot in wet conditions
The taproot is highly susceptible to fungal rot if soil is waterlogged or poorly drained. Site in raised beds or very free-draining ground. Do not water again until the surface soil has dried.
Poor germination when sown in spring
Seeds have complex dormancy and germinate best after a cold, moist period (natural stratification). Autumn sowing in situ or refrigerated stratification for 4–6 weeks before spring sowing dramatically improves germination rates.
Powdery mildew
Can appear on foliage in warm, humid periods. Ensure adequate plant spacing (25–30 cm) and good airflow. A preventative spray of dilute potassium bicarbonate is effective at early stages.
Prevent white laceflower problems before they start
Most white laceflower issues are care-mismatch, not bad luck. Dial in the basics:
