Plant Needs
Sunlight
Requires full direct sunlight for 6–8 hours daily; provide partial shade during midday summer heat in extremely hot climates to prevent sunscald
Watering
Water deeply only when the entire soil medium is completely dry; avoid standing water to prevent root rot
Temperature
Thrives in 15–30°C; tolerates brief light frosts down to 5°C but will suffer damage if exposed to prolonged temperatures below 0°C
Characteristics
- Stem: Segmented cylindrical pads, covered in tiny barbed spines (glochids) along raised areoles
- Leaf: Small, short-lived leaves that drop within weeks of sprouting
- Flower: Bright yellow, cup-shaped blooms emerging at the tips of mature stem segments
- Fruit: Small, oval red berries dotted with glochids
Care Guide
Watering
Water deeply when the top 10–15 cm of soil is completely dry; avoid overwatering to prevent root rot
Fertilization
Diluted cactus fertilizer applied once monthly. Discontinue fertilization in autumn and winter when growth slows
Eggshell powder topdress：Crush thoroughly dried eggshells into a fine powder, then sprinkle a thin layer on the soil surface; avoid direct contact with stem segments to prevent irritation from sharp shell particlesPruning
- Wear thick protective gloves to avoid glochid exposure while pruning
- Remove dead, damaged, or diseased stem segments at the base to maintain plant health and shape
- Trim overgrown stems in early spring to encourage bushier, more compact growth
- Dispose of pruned segments carefully to prevent accidental glochid contact with humans or pets
Toxicity
Warning: this plant may be toxic.
