Diseases & Pests:
Lobelia can be susceptible to leaf spot and crown rot, but this can be avoided by placing in a location with plenty of air flow, watering mornings only and avoiding overly saturated soils. Slugs can occasionally be a problem, but can be treated by applying pelletized iron phosphate. Diatomaceous earth can also be used.
