Growth Stages

1

Establishment

2-4 weeks

Newly planted rosette focuses on root development with minimal leaf growth

Keep soil barely moist for first 2-3 weeks; place in bright indirect light; avoid fertilizing

2

Vegetative Growth

1-2 years

Rosette expands with new warty leaves emerging from center; plant gradually increases in size

Water when soil is completely dry; fertilize sparingly (1-2 times per year with diluted succulent fertilizer); maintain cool winter rest period

3

Offsetting

Ongoing after 2+ years

Plant produces 'pups' or young rosettes around the base of the mother plant

Allow offsets to establish before separation; continue regular watering and care schedule

4

Flowering

2-4 weeks

Distinctive tubular, pale green or yellow flowers emerge on tall flower spikes in spring/early summer

Provide cool winter dormancy (50-60°F) to encourage flowering; flowering indicates plant maturity

5

Post-Flowering

1-2 months

Flowers fade and drop; plant enters summer growth or dormancy depending on temperature

Reduce watering if dormant; resume normal watering if actively growing
