Keep soil consistently moist; provide bright indirect light; thin seedlings to 2 inches apart once true leaves appear
Vegetative Growth
4-6 weeksSquare stems with opposite, aromatic, lance-shaped leaves; plant establishes strong root system and develops branching structure
Water regularly; pinch back tips when 6-8 inches tall to encourage bushiness; apply balanced fertilizer every 4 weeks
Pre-flowering/Bud Formation
2-3 weeksCompact flower buds form at stem tips; plant reaches full height of 2-3 feet; leaves remain vibrant green
Continue regular watering; reduce nitrogen fertilizer; ensure good air circulation to prevent mildew; stake if needed in windy areas
Flowering
8-12 weeksDense, shaggy scarlet-red flower heads bloom abundantly; flowers attract hummingbirds and bees; blooms continuously mid-summer to fall
Deadhead spent flowers to encourage more blooms; water at soil level to keep foliage dry; watch for powdery mildew; fertilize lightly monthly
Seed Production/Senescence
4-8 weeks before dormancyFlowers fade to rust-brown; seed heads form and mature; foliage yellows as temperatures cool in fall
Leave seed heads for wildlife and self-seeding if desired; cut back after frost or in early spring; divide plants every 3-4 years to rejuvenate

Harvest Tips
Pinch or deadhead flowers regularly from mid-summer onward to extend bloom season and encourage fuller shape. For tea, harvest leaves in morning after dew dries. For edible flowers, pick fresh blooms as they fully open. Cut stems back to 4-6 inches in fall after frost, or in early spring before growth resumes.
