Continue watering deeply. Apply balanced fertilizer if soil is poor. Provide staking or support if growing in windy locations.
Flowering
8-12 weeks (late August through October/November)Prolific daisy-like flowers with red, orange, and gold petals and prominent yellow-brown central discs bloom continuously
Deadhead spent flowers regularly to encourage continued blooming and extend the season. Water during dry periods. Monitor for pests and diseases.
Senescence
Variable, until hard freezeFlowering slows as temperatures drop in late fall; foliage may yellow or brown
Allow some flowers to remain on plant for winter interest and bird food. Cut back stems in late fall or early spring. Divide established clumps in spring.
