How to Plant​

The Cork Monkey Puzzle (Araucaria araucana ‘Cork’) is an intriguing conifer that captures attention with its unique appearance and cork-like bark. To successfully plant and cultivate this tree, follow these steps for optimal results.

Site Selection: Choose a location with full sun to partial shade, ensuring decent air circulation. The soil should be well-draining and preferably sandy or loamy to prevent waterlogging.

Preparation: Dig a hole about two to three times wider than the root ball and approximately the same depth. Amend the soil with organic compost to improve drainage and nutrient content.

Planting: If you're starting with a container-grown plant, gently remove it from the pot, taking care not to disturb the roots excessively. Place the tree in the center of the hole, ensuring that the top of the root ball is level with the soil surface. Fill in around the roots with the amended soil, pressing gently to eliminate air pockets.

Watering and Mulching: Water thoroughly after planting to settle the soil. Apply a layer of mulch around the base to retain moisture and suppress weeds.

Care: Keep the area around the Cork Monkey Puzzle free from weeds, and water regularly during dry spells, especially in the first few years, to promote healthy growth.

Watering​

Cork Monkey Puzzle (Araucaria columnaris) requires careful watering to ensure healthy growth and prevent root rot. The best strategy involves a balance between maintaining moisture and allowing for adequate drainage. Begin by checking the top inch of the soil; if it feels dry, it's time to water. Utilize a thorough watering technique, allowing water to permeate the soil completely until it drains from the bottom of the pot.

During the growing season (spring and summer), keep the soil consistently moist, but not soggy. Reduce watering in the fall and winter months when the plant's growth slows. Ensure your pot has drainage holes, and avoid letting the plant sit in water. Additionally, consider factors like humidity and temperature, as higher humidity may reduce the need for frequent watering. Regularly monitoring the plant's condition will help you adjust your watering routine for optimal health.

Pruning​

Pruning a Cork Monkey Puzzle plant (Araucaria araucana), known for its unique corky bark and spiky foliage, is essential for maintaining its health and appearance. The best strategy involves pruning during its dormant season, typically in late winter or early spring. Begin by assessing the tree's structure; remove any dead, damaged, or crossing branches to promote better airflow and prevent disease.

When pruning, focus on maintaining the natural shape of the tree, as over-pruning can lead to unsightly growth. Cut back branches to just above a healthy bud, ensuring that cuts are clean and made at a slight angle. This approach encourages new growth and minimizes stress on the plant. Avoid heavy pruning, as these trees are slow-growing and may take a long time to recover. A light touch allows the Cork Monkey Puzzle to thrive while retaining its distinctive silhouette.

Weeding​

Weeding around a Cork Monkey Puzzle plant (Araucaria columnaris) requires a careful approach to protect its unique trunk and sprawling branches. First, it’s essential to identify the weeds and their roots without disturbing the Monkey Puzzle. Using a hand trowel or a weeding fork can help in gently loosening the soil around the weeds.

Start by pulling out the weeds when the soil is damp, as they will come out more easily with less risk of damaging nearby roots. Be cautious of the plant’s foliage and avoid any heavy machinery that might harm its bark or nearby roots.

Mulching around the plant with organic materials, like wood chips or bark, can suppress future weed growth and retain moisture. Regularly check the area to promptly remove any emerging weeds, ensuring the Cork Monkey Puzzle has the space and nutrients it needs to thrive.
