Echinopsis subdenudata f. cristata 'Frosty Top' (syn. subdenudatus)
cancel Sold out
Echinopsis subdenudata f. cristata 'Frosty Top' is a unique crested cactus with dense, white spination that gives it the striking appearance of a snow-covered mountain ridge. Originating from a mutation in the standard Echinopsis subdenudata, this rare form has a fascinating, undulating structure combined with a frosty, woolly texture.
Care Tips
- Light: Prefers bright, indirect sunlight or partial shade; excessive direct sun can scorch its spines.
- Water: Water sparingly, allowing the soil to dry out completely between waterings; reduce significantly in winter.
- Humidity: Tolerates low humidity; thrives in dry conditions.
- Media: Requires a well-draining cactus mix with added sand or perlite to prevent root rot.
- Temperature: Best suited for warm temperatures between 18-30°C; avoid exposure to frost.
- Fertiliser: Feed with a diluted cactus fertiliser every 4-6 weeks during spring and summer.
- Repotting: Infrequent repotting is needed as it prefers being slightly root-bound.
