Detailed Care Instructions
Light Requirements
Place in full sun outdoors or the brightest indoor window. Insufficient light means fewer blooms and leggy growth. Rotate pots weekly so stems do not lean hard toward one window.
Watering
Keep evenly moist in summer heat; let the top soil dry slightly between waterings in cooler months. Wilting in midday heat often recovers after a deep drink — persistent wilt with wet soil suggests root stress.
Feeding
Use a bloom-focused fertilizer during active growth. Flush pots occasionally to avoid salt buildup that burns leaf edges. Cut fertilizer when overwintering indoors.
Winter Care
In cold regions, grow as an annual or overwinter indoors above freezing with reduced watering and the brightest spot available. Expect some leaf drop after the move; new growth resumes with longer days.
Pruning for Shape
Pinch soft tips early in the season for bushier plants. Hard pruning is best after a bloom flush so you do not remove too many forming buds at once.
