Pinch back growing tips once or twice to encourage bushier growth. Water moderately. Apply balanced fertilizer every 2-3 weeks. Ensure good drainage.
Budding
2-3 weeksTight flower buds appear at branch tips, initially appearing as small green knobs that swell and develop sepals.

Flowering

Deadhead spent flowers regularly to promote continuous blooming. Water during dry periods. Reduce nitrogen to prevent excessive leaf growth at flowering expense. Enjoy cut flowers.
Decline/End of Season
VariableFlowering slows as temperatures rise (heat stress) or as season progresses into fall/winter. Plants may decline in appearance.
In hot climates, provide afternoon shade or allow plants to rest. Cut back faded plants by half to rejuvenate. In cooler zones, may persist through winter. Remove dead foliage.
