Seedling
2-3 weeksSmall plants with 2-4 true leaves, tender green stems. Cotyledons present initially, replaced by true leaves within 1-2 weeks.
Keep soil warm (70-75°F) and consistently moist. Provide bright light. Thin to strongest seedlings or transplant to individual cells.
Vegetative Growth
3-4 weeksCompact, bushy plants with increasingly dense foliage. Plant height reaches 12-18 inches. Multiple leaf nodes develop along branching stems.
Pinch main stem once or twice when 4-6 inches tall to encourage bushiness (optional with Profusion). Gradually harden off transplants. Plant outdoors after frost danger passes.
Flowering
8-12 weeksPlant becomes covered with 1.5-2 inch double white flowers. Blooms appear in clusters at branch tips. Flowers remain abundant with minimal deadheading.
Apply balanced or low-nitrogen fertilizer every 2-3 weeks. Deadhead spent flowers to encourage more blooms, though less critical than traditional zinnias. Monitor for powdery mildew in humid conditions.
Peak Production
4-8 weeksMaximum flower output with continuous blooming. Plant maintains vigor and dense flower coverage throughout mid to late summer.
Continue regular watering and feeding. Ensure good air circulation. Remove any diseased foliage promptly.
Late Season/Frost
Until frostFlowering continues until first hard frost (32°F). Flowers may diminish slightly in cooler fall temperatures. Plant gradually declines after frost damage.
Allow some flowers to remain on plant for seed collection if desired. Pull entire plant once killed by frost.

Harvest Tips
Cut flowers in early morning when blooms are freshly opened for longest vase life. Use sharp pruners to cut 6-8 inches of stem. Remove lower foliage and place in cool water immediately. Flowers last 7-10 days in a vase. For seed saving, allow a few late-season flowers to dry on plant before frost; collect and dry seeds thoroughly before storing.
