Germination & Seedling
10-14 days to germination; 4-6 weeks to transplant sizeTiny seedlings with fine, thread-like leaves emerge. Plants are delicate and small.
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing when 2-3 inches tall.
Establishment & Vegetative Growth
4-8 weeks after transplantingPlant develops bushy form with increasing fine, feathery foliage. No flowers yet.
Water regularly to establish deep root system. Pinch back growing tips at 4-6 inches tall to encourage branching and bushier growth. Mulch lightly around base.
Bud Formation & Early Flowering
2-4 weeksGolden-yellow buds form at stem tips. First flowers appear.
Reduce watering frequency as plant becomes established. Deadhead spent flowers to encourage continuous blooming. Begin weekly fertilizing with balanced or low-nitrogen fertilizer if desired.
Peak Bloom
6-10 weeks (summer through early fall)Plant is covered with abundant golden-yellow daisy-like flowers. Foliage is soft and feathery.
Continue deadheading regularly to extend blooming. Water only during drought conditions. Fertilize sparingly—excessive nitrogen reduces flowering. Enjoy abundant blooms.
Late Season & Dormancy
Fall through winterFlowering decreases as temperatures cool. Foliage may turn reddish. Plant prepares for winter.
Reduce deadheading to allow some flowers to go to seed for natural reseeding. Allow spent foliage to remain for winter interest and as protective covering. Divide every 3-4 years in spring.
