Germination & Early Seedling
2-4 weeksTiny seedlings with small oval cotyledons emerge; caudex begins forming at base
Keep soil lightly moist (not wet); provide bright indirect light; maintain warm temperatures (75-85°F); ensure excellent air circulation to prevent fungal issues
Juvenile Growth
6-12 monthsCaudex enlarges and becomes more prominent; first true leaves and stems develop; plant remains relatively compact
Gradually increase sun exposure; transition to mature watering schedule (soak then dry); begin very light fertilization; ensure drainage is excellent
Vegetative Development
1-2 yearsSubstantial growth of stems and foliage; caudex continues swelling; plant develops characteristic shape and structure
Maintain full sun exposure; water deeply when soil is dry; apply dilute fertilizer monthly during growing season; prune to encourage branching if desired
Flowering
2-4 months per flowering seasonTerminal clusters of 2-5cm pink, red, or white flowers appear at stem tips; blooms are showiest in spring and early summer
Continue full sun; maintain proper watering schedule; refrain from pruning during bloom; provide balanced or slightly phosphorus-rich fertilizer to encourage flowers
Dormancy
2-3 months (winter)Foliage yellows and drops; plant slows or stops growth; caudex stores energy reserves
Reduce watering to minimal (water only if plant is severely shriveled); stop fertilizing; maintain cool temperatures (50-65°F if possible); allow leaf drop to occur naturally
