Echinopsis Subdenudata (Domino Cactus)

• Native to South America, particularly Bolivia and northern Argentina, where it grows in rocky, well-draining soils at high altitudes.
• Forms a distinctive globe shape that can slowly cluster with age, creating attractive groupings of spherical stems covered in geometric spine patterns.
• Produces stunning large white flowers up to 20cm across that open at night and emit a powerful sweet fragrance to attract nocturnal pollinators.
• Beloved by collectors for its reliable blooming habit and impressive floral display that can last several days during the warmer months.

• Water thoroughly once every 2-3 weeks in summer, allowing soil to dry completely between waterings, and reduce to monthly in winter.
• Position in bright, indirect light indoors or morning sun with afternoon shade outdoors to prevent sunburn while maintaining healthy growth.
• Use a well-draining cactus potting mix with added perlite or pumice to ensure excellent drainage and prevent root rot.
• Feed monthly during spring and summer with diluted low-nitrogen cactus fertiliser, avoiding feeding during winter dormancy period.
• No pruning required except to remove any damaged or diseased sections using sterilised tools to prevent infection.
• Maintain low humidity and good air circulation, avoiding placement near humidifiers or in enclosed spaces.
• Provide cooler winter temperatures around 10-15°C to encourage spring flowering and maintain plant health through seasonal cycles.

• Provide bright, indirect light indoors or morning sun with afternoon protection outdoors. Avoid sudden changes in light exposure to prevent sunburn.
• Water deeply but infrequently, allowing soil to dry completely between waterings. Reduce watering significantly in winter months when growth slows.
• Maintain low humidity and ensure excellent air circulation around the plant. Avoid humid locations like bathrooms or enclosed terrariums.
• Keep temperatures between 18-24°C for optimal growth, with cooler winter temperatures around 10-15°C to encourage flowering. Protect from frost.
• During spring and summer growing season, provide monthly feeding with low-nitrogen cactus fertiliser diluted to quarter strength.

• Overwatering causes root rot and soft, yellowing stems - reduce watering immediately and ensure excellent drainage. Allow soil to dry completely between waterings.
• Scale insects appear as small brown bumps on the cactus surface - remove with rubbing alcohol on a cotton swab. Treat regularly until eliminated.
• Mealybugs create white cottony masses in spine clusters - dab with rubbing alcohol or spray with horticultural oil. Isolate affected plants to prevent spread.
• Sunburn causes yellow or brown patches on the cactus body - gradually acclimate to bright light and provide afternoon shade in extreme heat.
