Austrocylindropuntia subulata f. cristata - How to Care for Your Crested Eve's Needle
 
Placement & Light
Requires bright, indirect to direct sunlight for at least 5–6 hours daily.
Ideal locations: South- or west-facing windows or under grow lights.
Avoid deep shade, as lack of light leads to weak, elongated growth.
 
Watering
Minimal watering needed—let the soil fully dry out between waterings.
Water every 2–3 weeks in spring and summer.
In winter, water only enough to prevent shriveling.
 
Humidity & Temperature
Prefers low humidity.
Thrives at 18–24°C but should never be exposed to temperatures below 5°C.
Cold-sensitive – move indoors in winter if grown outdoors.
 
Soil & Pot Selection
Requires a well-draining cactus/succulent mix with added sand or perlite.
Use a terracotta pot with drainage holes to prevent overwatering.
 
Repotting
Repot every 2–3 years in a slightly larger pot.
Handle carefully to avoid breaking delicate crested stems.
 
Fertilizing
Feed with a low-nitrogen cactus fertilizer every 4–6 weeks during the growing season.
No fertilizer is needed in winter.
 
Propagation
Propagate from stem cuttings, allowing them to callous over for a few days before planting.
Do not water cuttings immediately—wait until roots develop.
 
Semi-Hydroponics
Not recommended for semi-hydroponic systems, as it prefers dry, well-aerated soil.
 
Pruning & Maintenance
Minimal pruning required.
Remove any reverting (non-crested) growth to maintain its sculptural form.
