Austrocylindropuntia subulata f. cristata - How to Care for Your Crested Eve's Needle

Placement and 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 and 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 and 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.


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 and Maintenance

Minimal pruning required.

Remove any reverting (non-crested) growth to maintain its sculptural form.
