Vegetative Growth
3-4 weeksPlants develop bushy, compact form with narrow lance-shaped gray-green leaves. Multiple stems branch from base.
Pinch back growing tips at 3-4 inches to encourage bushier growth. Maintain consistent moisture. Begin fertilizing weekly with balanced fertilizer.
Bud Formation
1-2 weeksFlower buds appear at stem tips. Plants continue to branch and fill out. Buds are tight and greenish.
Reduce nitrogen slightly, increase phosphorus to promote flowering. Maintain consistent watering. Remove any dead foliage.
Flowering
6-10 weeks (continuous with deadheading)Abundant double white flowers with ruffled petals open continuously. Blooms are 1-1.5 inches across on 12-18 inch tall plants.
Deadhead spent flowers regularly to encourage continuous blooming. Water consistently. Fertilize every 2-3 weeks. Provide support if needed in windy locations.
Extended Bloom & Senescence
Remaining seasonFlowering continues through season; plants may slow production in intense heat (above 85°F). Eventually set seed if flowers not removed.
Continue deadheading to extend bloom. Reduce watering slightly if heat stress occurs. Prepare to replace annuals in fall or collect seeds for next year.
