Care essentials
Light
Provide full sun — at least 6 hours of direct light daily. In NE Florida, plant in a bright, open bed for the strongest bloom production during the cool season.
Water
Water regularly to keep soil evenly moist but never soggy; avoid overhead irrigation as wet foliage promotes powdery mildew in Florida's humid conditions. Water at the base and allow the top inch of soil to dry slightly between waterings.
Soil & Fertilizer
Plant in well-drained, slightly alkaline to neutral soil (pH 6.5–7.0). Apply a balanced granular fertilizer at planting and monthly during the cool season; avoid excess nitrogen, which promotes foliage at the expense of flowers.
