ðŸŒą How to Care for Figworts to Prevent Downy Mildew?

💧 How to Water

Keep the soil moist at all times, watering every 2 to 4 days in hot weather. S. auriculata tolerates wet, boggy soil at pond edges; S. nodosa copes with short dry spells once established.

Prefers dappled light or partial shade but takes full sun if the soil does not dry out. In deep shade it flowers poorly.

ðŸŠī Ideal Soil

Fertile, moist clay or loam with a slightly acidic to alkaline pH (5.5 to 7.5). Avoid fast-draining sandy soil unless you can water often.
