Continue watering regularly. Deadheading is optional but can extend bloom. Feed every 3-4 weeks with bloom-boosting fertilizer. Monitor for pests.
Senescence
Variable; frost kills annuals in cold climatesPlant slows flowering in very hot summer or as temperatures cool in fall; growth may decline.
In mild climates, prune back lightly in mid-summer to rejuvenate for fall bloom. Reduce watering slightly. Prepare for dormancy or end-of-season cleanup.
