Germination & Seedling
10-14 daysSeeds sprout within 7-10 days; true leaves emerge after the rounded cotyledons
Keep soil consistently moist but not waterlogged. Provide bright light if indoors; thin seedlings to proper spacing once they have 2-3 true leaves
Leaf Development
14-21 daysPlant develops 6-8 true leaves; loose leaf structure begins forming
Maintain even moisture and cool temperatures (55-65°F ideal). Begin light fertilizing with balanced or nitrogen-rich fertilizer. Mulch to conserve moisture and keep soil cool
Head Formation
14-21 daysLeaves overlap and begin forming a loose, tender head; inner leaves lighten in color
Continue consistent watering and feeding every 2-3 weeks. Reduce nitrogen slightly to encourage head firmness. Remove any yellowing outer leaves
Head Maturity
7-14 daysHead becomes full, buttery, and tender with a slight firmness at the center; plant reaches harvest size
Maintain moisture consistency. Watch for bolting signals (flower stalk emergence); harvest immediately if temperatures exceed 75°F
Post-Harvest
OngoingPlant may be cut at soil level or roots can be left for regrowth in cool seasons
If regrowing, keep well-watered and continue light fertilizing. Use harvested leaves promptly for best quality

Harvest Tips
Harvest when heads feel firm but tender, typically 60-80 days after planting. Cut the entire head 1 inch above soil level with a sharp knife in the early morning for crispness. For extended harvest, pick outer leaves individually while allowing the center to continue growing. Butterhead is prone to bolting in heat; harvest before temperatures consistently exceed 75°F.
