Echinocactus Grusonii "Golden Barrel" Cactus

• Native to central Mexico, this iconic barrel cactus has become a symbol of desert landscapes worldwide. It's also known as Mother-in-Law's Cushion for its formidable spines.
• Features a perfectly round shape with prominent golden-yellow spines arranged in neat vertical rows. The geometric patterns create stunning shadow play in garden settings.
• Grows slowly but can eventually reach 60-120cm tall and wide over many decades. Mature specimens may produce a crown of bright yellow flowers in summer.
• Beloved by collectors for its architectural form and low-maintenance nature. Perfect for creating dramatic focal points in xerophytic and contemporary garden designs.

• Water every 2-3 weeks in summer, monthly in winter, allowing soil to completely dry between waterings. Check soil moisture with your finger 5cm deep.
• Position in full sun locations receiving 6+ hours direct sunlight daily. Indoors, place near south-facing windows or supplement with grow lights.
• Plant in well-draining cactus mix or add perlite and sand to regular potting soil. Ensure all containers have adequate drainage holes.
• Feed with diluted cactus fertiliser monthly during spring and summer growing season. Avoid fertilising in autumn and winter when growth slows.
• No pruning required - never cut healthy tissue as it won't regrow. Remove any damaged or diseased areas with sterile tools.
• Tolerates low humidity typical of Australian homes. Provide good air circulation to prevent fungal issues in humid conditions.

• Provide full sun exposure for at least 6 hours daily to maintain golden spine colour and compact growth. Indoor plants need south-facing windows or grow lights.
• Water deeply but infrequently, allowing soil to dry completely between waterings - typically every 2-3 weeks in summer, monthly in winter. Reduce watering significantly during cooler months.
• Use well-draining cactus potting mix and ensure containers have drainage holes. Add extra perlite or pumice to regular potting mix if needed.
• Maintain temperatures between 18-30°C for optimal growth. Protect from frost but allow some winter cooling to encourage flowering in mature plants.

• Overwatering causes root rot and soft, yellowing tissue - ensure soil dries completely between waterings and use well-draining cactus mix. Check for mushy areas at the base which indicate rot.
• Scale insects appear as small brown bumps on the surface - remove with rubbing alcohol on a cotton swab. Inspect regularly as scales can spread quickly in warm conditions.
• Mealybugs create white cottony masses in spine clusters - treat with neem oil spray or alcohol wipes. Isolate affected plants to prevent spread to other cacti.
