[[RESEARCH ENRICHMENT START]]
Zone 6B: Direct sow after frost and succession sow every 1-2 weeks for continuous cut-flower harvest. Indoor starting 2-3 weeks before planting out is possible for the earliest crop.
Germination: Germinates in 7-14 days at 70-75°F. Avoid disturbing roots when transplanting.
Harvest: Harvest tight when petal color first becomes visible or allow flowers to open further depending on intended use.
Seed Saving: ProCut White Lite is an F1 hybrid and pollenless; saved seed will not reliably reproduce the cultivar.
Special Care: Do not pinch. This is a single-stem cut-flower cultivar; pinching can produce poor-quality flowers or prevent normal bloom development.
