Seedling
2-3 weeksTiny leaves emerge with true leaves developing slowly. Plants are fragile and low-growing.
Keep soil consistently moist but not waterlogged. Provide bright light and good air circulation to prevent damping off.
Vegetative Growth

Bud Formation
2-4 weeksSmall flower buds appear throughout the plant in late summer. The plant becomes increasingly dense with buds.
Reduce nitrogen fertilizer to promote flowering over leaf growth. Ensure adequate moisture as buds develop.

Deadhead spent flowers to encourage continuous blooming. Water consistently at soil level. Cut back stems that become leggy.
Dormancy
3-4 months (December-March)Plants die back or become semi-dormant after frost. Above-ground growth withers.
