Deadhead spent flowers regularly to encourage continuous blooming. Fertilize every 2-3 weeks with balanced fertilizer or flower-specific formula. Water at soil level.
Sustained Bloom & Decline
4-6 weeks until frostPlants continue flowering profusely but may slow as temperatures rise significantly or frost approaches. Foliage may appear tired in peak summer heat.
Provide afternoon shade in hot climates (above 85°F consistently). Continue deadheading. Reduce watering as days shorten in fall. Treat as annual or dig and store if in borderline zones.
