Germination & Seedling
10-14 daysTiny seedlings with first true leaves appearing; very delicate
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing to prevent damping off.
Vegetative Growth
3-4 weeksBushy plants developing multiple stems and narrow, blue-green foliage; no flowers yet
Pinch back growing tips when 3-4 inches tall to encourage branching. Light fertilizing with balanced formula (once weekly or every other week). Ensure good air circulation.
Budding & Early Flowering
2-3 weeksFlower buds forming at branch tips; first blooms opening in the intended color
Reduce nitrogen to encourage more flowers; use phosphorus-rich fertilizer. Deadhead spent flowers immediately to promote continuous blooming. Water consistently.
Peak Flowering
6-10 weeks or morePlant covered in abundant small, ruffled flowers; strong fragrance if variety has it
Deadhead regularly every 2-3 days. Water moderately and maintain good drainage. In heat, provide afternoon shade. Feed sparingly with low-nitrogen fertilizer every 2-3 weeks.
Decline (Late Summer/Fall)
VariableFlowering may slow in peak summer heat; plant may rest before fall rebloom in cooler climates
Cut back spent growth if needed; water less if temperatures drop. In mild climates, may continue blooming into fall; in hot climates, may benefit from a summer rest and return vigor in cooler weather.
