Apache War Club

Pachycereus pecten-aboriginum, commonly known as the Mexican Fencepost Cactus or Hairbrush Cactus, is a striking columnar cactus native to Mexico. It is known for its tall, straight growth habit and is often used as a natural fence in its native habitat.

This cactus typically grows to a height of 15 to 30 feet, and under ideal conditions, it can reach towering heights of up to 50 feet. Its spread is about 6 to 10 feet. Pachycereus pecten-aboriginum forms upright, cylindrical stems that are dark green in color, with pronounced vertical ribs. The stems are lined with evenly spaced, small spines that resemble a hairbrush, hence one of its common names.

One of the attractive features of this cactus is its nocturnal flowers. The plant produces large, white or cream-colored blooms that open at night and close by morning. These are followed by red, fleshy fruits that are edible and attract various wildlife.

Pachycereus pecten-aboriginum thrives in full sun and requires well-draining soil. It's drought-tolerant, making it an excellent choice for xeriscaping, dry gardens, and desert landscapes. Due to its tall, columnar form, it's often used as a living fence or privacy screen and as an architectural element in gardens.

In landscaping outside of its native range, it's often used as a statement plant in cactus and succulent gardens or as an ornamental feature in large containers.

Overall, Pachycereus pecten-aboriginum is a low-maintenance and visually impressive plant, perfect for adding height and structure to a garden. Its striking form, night-blooming flowers, and adaptability to arid conditions make it a valuable and attractive addition to landscapes in suitable climates.

Three Timbers Installation Guide (Feel Free to Follow): Apache War Club

Planting Guide:

• Location: Full sun (at least 6 hours of direct sunlight daily)
• Soil: Well-drained, sandy or loamy soil (tolerates slightly acidic to alkaline soils)
• Spacing: Space plants 3-4 feet apart to allow for their mature size and optimal airflow
• Planting Depth: Plant at the same depth as the root ball, ensuring the top of the root ball is level with the surrounding soil surface
• Support: No staking is typically required; this plant is self-supporting and grows in a bushy form

Watering Guide:

Watering After Planting:

• Initial Watering: Water thoroughly immediately after planting to saturate the root ball and surrounding soil
• Frequency: Water every 2-3 days for the first 2 weeks to help establish the root system
• Watering Amount: Provide 1-1.5 inches of water per session to ensure deep watering around the root zone

When is the Plant Established?

• Timeframe: The Apache War Club is considered established after 2-3 months, once the roots have spread into the surrounding soil and the plant begins showing consistent new growth

Watering Once Established:

• Summer: Water every 7-10 days during the hot months. If temperatures exceed 100°F, increase watering to every 5-7 days. Provide 2 inches of water per session.
• Winter: Water every 3-4 weeks, depending on rainfall. The Apache War Club is drought-tolerant once established, but it still benefits from occasional watering during dry winters.

General Watering Tips:

• Soil Check: Regularly check the soil moisture. Water when the top 2-3 inches of soil feel dry to the touch.
• Avoid Overwatering: The Apache War Club prefers dry conditions and well-drained soil. Overwatering can lead to root rot.
• Mulch: Apply a thin layer of mulch around the base to help retain moisture, keep the roots cool, and prevent weeds. However, avoid piling mulch directly against the plant’s stem.
