Troubleshooting
Baikal Skullcap problems — and how to fix them
Baikal Skullcap (Scutellaria baicalensis) 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 soils
The most common cause of plant death. Ensure excellent drainage — raise beds or add 30–50% grit to planting holes. In containers use a cactus-mix base. Remove affected roots promptly and dust with sulphur before replanting.
Slow germination
Seeds have variable dormancy and can take 3–6 weeks to sprout even in optimal conditions (18–22°C). Cold-stratify seed for 2–4 weeks in damp sand in the refrigerator before sowing to improve germination rates.
Powdery mildew
Occasionally affects plants in humid summers. Improve air circulation by thinning crowded stems and avoid wetting foliage when watering. A dilute bicarbonate of soda spray (1 tsp per litre) applied fortnightly can suppress early infections.
