Pinch back growing tips to encourage bushier growth and more branches, maintain moisture, provide bright indirect light, fertilize every 2 weeks with balanced fertilizer
Budding
2-3 weeksSmall buds form along the stems and leaf axils, plant looks fuller
Continue pinching if desired for fuller form, maintain consistent watering, increase light exposure, reduce nitrogen fertilizer to encourage flowering
Flowering

Deadhead spent flowers to encourage continuous blooming, maintain consistent moisture, provide bright indirect light, apply balanced or slightly high-phosphorus fertilizer weekly
Late Season
4-8 weeksFlowering continues but may slow in heat; plant prepares for dormancy in cooler zones
