Vegetative Growth
Spring through early summer, approximately 6-8 weeksLeafy stems elongate with variegated cream and green foliage becoming more prominent; plant fills out its branching structure
Water regularly; fertilize monthly with balanced 10-10-10 fertilizer or hydrangea-specific formula; monitor for pests; pinch tips to encourage bushiness in early season
Flowering
Mid-summer through fall, 8-12 weeks depending on climateLarge panicle flower clusters develop with distinctive white petals edged in hot pink or red; flowers may shift color based on soil pH and aluminum availability
Continue consistent watering; deadhead spent flowers to encourage more blooms; avoid pruning during flowering; feed with flower-promoting fertilizer (higher phosphorus)
Senescence
Fall through winter, 4-5 monthsFlowers fade and dry on the plant; foliage begins to yellow; plant prepares for dormancy
Reduce watering gradually; stop fertilizing; remove dead or diseased wood; prune after last frost to shape plant and remove winter damage; avoid pruning in late summer/fall as it encourages tender new growth
Dormancy
Winter, approximately 2-3 months depending on regionPlant is leafless with woody stems visible; dormant buds form along stems for next season's growth
Minimal water needed; protect in extreme cold below -10°F with burlap wrapping or mulch mounding; inspect for winter damage; apply pruning sealer if needed
