The Details
• Botanical Name: Weberbauerocereus johnsonii
• Common Name: Golden Columnar Cactus
• Pot Size: 70mm Nursery Pot
• Plant Type: Columnar desert cactus
Light
The Golden Columnar Cactus loves sunshine and performs best in a position receiving plenty of bright natural light.
Indoors, place it near a sunny north-facing window where it can receive several hours of direct sunlight throughout the day. A bright, unobstructed position will help maintain strong, compact growth and its beautiful golden spines.
Outdoors, this species appreciates a sunny, well-ventilated location, although young plants should be gradually introduced to intense sunlight to prevent scorching.
During Melbourne's warmer months, established plants can enjoy plenty of sunshine, but some protection from extreme afternoon heat may be beneficial while they acclimatise.
Insufficient light can cause the stem to become thin, stretched or misshapen as the cactus grows towards a stronger light source.
Watering
Like most desert cacti, Weberbauerocereus johnsonii prefers a thorough watering followed by a complete drying period.
During spring and summer, water deeply once the potting mix has dried out completely. Allow excess water to drain freely and never leave the pot sitting in standing water.
As temperatures begin to cool in autumn, gradually reduce watering to reflect the plant's slower growth.
During winter, keep the cactus considerably drier, particularly if it is growing in cool conditions. Occasional light watering may be necessary in a warm indoor environment, but only once the growing medium is thoroughly dry.
Overwatering is one of the biggest risks for this species, especially when temperatures are low and the soil remains damp for extended periods.
Always consider the plant's environment, pot size and growing medium rather than following a fixed watering schedule.
Feeding
Feed your Golden Columnar Cactus throughout the year according to its growing conditions and seasonal activity.
During spring and summer, apply a diluted cactus and succulent fertiliser approximately every four to six weeks to support healthy stem development and strong growth.
As temperatures cool and growth begins to slow, reduce the frequency of feeding.
During a cool winter rest, fertilising is generally unnecessary. Resume feeding when warmer temperatures encourage active growth.
A fertiliser relatively low in nitrogen is ideal, helping maintain firm, compact growth rather than encouraging soft, elongated stems.
Avoid overfertilising, as cacti generally require fewer nutrients than many tropical houseplants.
Growing
Weberbauerocereus johnsonii is an upright-growing cactus native to Peru, where it naturally occurs in dry, rocky environments.
Its distinctive columnar stems feature prominent vertical ribs lined with clusters of fine, golden-yellow spines. These dense spines give the plant its beautiful glowing appearance, particularly when illuminated by sunlight.
As the cactus matures, its stem gradually becomes taller and more substantial, maintaining its characteristic upright form. Under suitable conditions, older specimens may eventually develop additional stems or branching growth.
Although relatively slow-growing in cultivation, this species has the potential to become a much larger plant over time.
For best results, plant in a very free-draining, mineral-rich growing medium that provides excellent aeration around the roots. Our Cacti & Succulent Mix is an ideal choice, helping prevent excessive moisture retention while supporting healthy root development.
Choose a pot with drainage holes and avoid moving into a significantly larger container before the roots require additional space.
The Golden Columnar Cactus appreciates warm temperatures during its active growing season and benefits from a cooler, dry rest during winter.
In Melbourne, protect it from frost, prolonged cold and winter rainfall. A bright indoor position, sheltered greenhouse or protected outdoor location is recommended during the colder months.
When repotting, wear thick gardening gloves or use folded newspaper to protect your hands from the sharp spines.
Pet Friendly?
Weberbauerocereus johnsonii is not generally regarded as chemically toxic to cats and dogs.
However, this cactus is not considered pet-safe due to its sharp spines, which can cause painful injuries to paws, mouths and curious noses.
Keep it well away from pets and young children, particularly as its dense golden spines may look softer than they actually are.
Good to Know
Despite its bright golden appearance, those beautiful spines are definitely not soft! Handle your Golden Columnar Cactus carefully and avoid placing it where it might be accidentally brushed against.
The golden colouring comes from the plant's naturally pigmented spines, which become particularly striking in strong natural light.
Young plants typically develop as a single upright column, gradually increasing in height and thickness as they mature.
Like many desert cacti, this species benefits from seasonal changes in temperature and watering. A cooler, drier winter rest can help maintain healthy growth over the long term.
Its compact 70mm nursery pot makes it a lovely starting point for collectors who enjoy watching unusual cacti develop and mature.
• We photograph as many of our plants as possible; however, some listings may occasionally use supplier images.
• As plants are living things, every plant is unique and natural variations in size, colour and fullness should be expected.
• The plant you receive may not be the exact one pictured, but we'll always hand-pick a beautiful, healthy plant we'd happily display in our own home.
