Water: Green finger is drought-tolerant, requiring thorough watering only when the soil is dry. During spring to fall, water once or twice a week; in winter, reduce to about once weekly. Use rainwater or distilled water, avoiding splashes on the stem to prevent rot.

Fertilize: During growing seasons (spring, summer, fall), fertilize green finger monthly with liquid fertilizer; none in winter. Incorporate slow-release fertilizer when repotting. Use nitrogen for seedlings and phosphate-potassium pre- and post-bloom. Apply low-concentration fertilizer multiple times to avoid issues like yellowing and slow growth.

Pruning: Green finger benefits from occasional pruning, particularly in early spring, to remove dead stems and promote airflow. This technique supports robust growth and maintains its shape. Always use clean tools to prevent infections and inspect for overgrowth to ensure health and aesthetics.

Propagation: Green finger, a member of the Cereus genus, is propagated by sowing in well-draining cactus mix. Seeds need shallow planting and moderate moisture in a warm, bright, but indirect sunlight environment. Patience is essential, as cacti germinate slowly; monitor moisture to avoid root rot.
