Crassula is a diverse genus of succulent plants renowned for their fleshy leaves and architectural forms. The genus includes around 200 species, ranging from small creeping varieties to upright shrubs. Crassula plants are prized for their drought tolerance and are popular as low-maintenance houseplants and landscape succulents.
Bright light is essential. Most Crassula thrive in full sun or bright indirect light. Insufficient light causes etiolation and weak growth.
Allow soil to dry completely between waterings. Succulent leaves store water; overwatering causes root rot. Water sparingly in winter.
Use gritty, well-draining succulent/cactus mix. Commercial succulent soil works well, or create your own with 50% potting soil, 50% perlite/pumice.
Ideal range 65°F-75°F (18°C-24°C). Can tolerate down to 50°F (10°C). Prefers dry air; avoid high humidity except during propagation.
Fertilize monthly during spring/summer with diluted succulent fertilizer (1/4 strength). Skip in fall/winter when plants are dormant.
Prune leggy growth in spring to maintain shape. Remove dead leaves promptly. Repot every 2-3 years in spring.
