🌱 How to Care for Strawflower to Prevent Aphids?

💧 How to Water

Water every 7 days, allowing the soil to dry out between waterings. Strawflower is drought-tolerant and very sensitive to overwatering. Reduce watering in winter. Never let the plant sit in standing water as this leads to root rot.

☀️ Lighting

Strawflower demands full sun — place it in the brightest spot available, ideally receiving at least 6-8 hours of direct sunlight daily. Inadequate light will cause poor flowering and leggy growth.

🪴 Ideal Soil

Use light, well-draining soil with a slightly acidic pH between 5.5 and 6.3. Avoid clay or heavy soils that retain moisture. Amend garden beds with sand or grit to improve drainage. Low phosphorus levels are preferred.
