Desert Cacti: Low-Maintenance, High-Character Houseplants

Botanical Name: Cactaceae family

Hundreds of species, all succulents. Distinguished by areoles (spine/flower-bearing spots). Golden barrel cactus (Echinocactus grusonii) — popular globe-shaped, slow to 3 ft diameter, yellow spines to 2 inches, yellow summer flowers.

Universal Cactus Care

Sun Is Non-Negotiable

South-facing window ideal. 2–3+ hours full sun daily. Most flower with enough sun (some need years to mature).

Repot Sparingly

Spring when roots fill pot. One size up only — too big holds water → rot. Terra cotta preferred (porous, dries faster).

Water: Seasonal

Spring–fall: regular while growing. Winter: sparing. Shriveled/wrinkled = underwatered — rehydrate with light water two days running. Never drench — rot risk.
