Cereus forbesii monstrose - Ming Thing

**Morphological Characteristics**

Cereus forbesii monstrose, commonly known as "Ming Thing," is a fascinating mutant form of the Cereus forbesii species, belonging to the Cactaceae family. Originating from South America, this cactus is prized for its unusual and sculptural growth habit. Unlike typical columnar cacti, Ming Thing features numerous short, irregular, lumpy, and contorted blue-green stems that grow in a dense cluster. Its distinctive "monstrose" growth results from genetic mutation, giving each plant a unique, almost alien appearance.

The stems are thick and fleshy, often reaching about 10-15 cm (4-6 inches) in height and spreading horizontally to about 20-30 cm (8-12 inches) over time. They are adorned with irregularly spaced areoles, each bearing short, stubby spines that are usually white to light brown. The overall texture of the plant is rough and bumpy, with deep creases and folds that enhance its sculptural charm. Flowers are rare in cultivation, but when they do appear, they are typically large, nocturnal, and white, like many other Cereus species.

**Growth Habits**

Ming Thing grows slowly and stays relatively compact, making it ideal for small containers or dish gardens. Over time, it develops a dense, mound-like form composed of many twisting stems. While it is not a vigorous spreader, with proper care, it can gradually form impressive, ornamental clumps. Its unique shape and slow growth rate make it highly desirable for collectors and enthusiasts who appreciate unusual cacti.

**Maintenance Points**

• Lighting: Ming Thing prefers bright, indirect light to full sun. In very hot climates, some afternoon shade is beneficial to prevent scorching. Indoors, placing it near a south- or east-facing window typically provides sufficient light.

• Watering: Water sparingly. During the active growing season (spring and summer), allow the soil to dry completely between waterings. In fall and winter, reduce watering significantly, providing just enough moisture to prevent shriveling. Overwatering is the most common cause of failure.

• Soil: Use a well-draining cactus or succulent mix. Amending the soil with additional perlite, coarse sand, or pumice is highly recommended to prevent water retention around the roots.

• Temperature: Ideal temperatures are between 18-27°C (65-80°F). Ming Thing can tolerate brief dips to around -1°C (30°F) if kept dry but should be protected from prolonged cold. It thrives best when kept above 10°C (50°F) during colder months.

• Fertilization: During the growing season, feed monthly with a diluted, low-nitrogen fertilizer suitable for cacti and succulents. Avoid fertilizing during the winter rest period.

• Potting: Ensure the container has good drainage. Repotting is recommended every 2-3 years or when the plant becomes pot-bound, preferably in early spring before the growing season begins.

• Humidity: Prefers low humidity and good air circulation. Avoid misting the plant, as moisture sitting on the stems can lead to fungal issues.

**Reproduction Method**

Cereus forbesii monstrose - Ming Thing can be propagated through stem cuttings, although patience is required due to its slow growth rate.

1. **Stem Cuttings:**

• Selection: Use a clean, sharp knife to remove a healthy segment from the parent plant.

• Callusing: Let the cutting dry and callus over for 5-10 days in a shaded, dry area.

• Planting: Place the callused end into a well-draining cactus soil mix. Plant shallowly to provide support.

• Aftercare: Water lightly after planting and place in a warm, bright spot out of direct sun until roots develop, which may take several weeks.

2. **Seeds:**

• Sowing: Ming Thing seeds are rare and difficult to find. If available, sow seeds on the surface of a sterile, well-draining seed mix.

• Germination: Keep lightly moist with high humidity and provide indirect light. Maintain a temperature of 20-25°C (68-77°F).

• Transplanting: When seedlings are strong enough, transfer them to individual pots with cactus soil.

**Additional Tips**

• Pest Control: Watch for common pests such as mealybugs and spider mites. Inspect regularly and treat infestations promptly with insecticidal soap or neem oil.

• Disease Prevention: Avoid overwatering and ensure excellent drainage to prevent root rot and fungal infections.

• Pruning: Remove dead or damaged stems with sterile tools to maintain a tidy appearance.

• Display: Ming Thing makes a striking statement in minimalist pots or grouped with other succulents and cacti for dramatic contrast.

• Safety Note: Though the spines are short, they can still cause minor skin irritation. Handle with care.

With its mesmerizing form and relatively low maintenance needs, Cereus forbesii monstrose - Ming Thing is a captivating addition to any cactus collection, offering a unique focal point in both indoor and outdoor gardens.
