Preparatory Steps

  1. Soil Preparation: Amend heavy clay soils with organic matter to improve drainage.
  2. Digging the Hole: The planting hole should be at least twice the width of the root ball and deep enough to accommodate it without crowding the roots.
  3. Watering: Water the sapling well after planting, and continue regular watering during the initial establishment phase.

In conclusion, the best time to plant a Monkey Puzzle tree is primarily in spring after the danger of frost has passed, although late fall planting is also an option in milder climates. By considering climate, site selection, and proper preparation, you can successfully establish this fascinating tree in your garden.

How to Plant

Planting a Monkey Puzzle Tree (Araucaria araucana)

The Monkey Puzzle tree, native to Chile and Argentina, is an iconic species known for its unique, spiky appearance. When planting this tree, proper preparation and consideration of its specific needs are essential for successful growth.

  1. Site Selection: Choose a sunny, sheltered location with well-draining soil. The Monkey Puzzle thrives in full sun but can tolerate partial shade. Ensure there's enough space for the tree to grow, as it can reach heights of up to 100 feet with a wide spread.

  2. Soil Preparation: While the Monkey Puzzle prefers slightly acidic to neutral soil, it is adaptable to various soil types. However, ensure good drainage. If your soil is heavy clay, consider mixing in sand or organic matter to improve aeration.

  3. Planting: Dig a hole that is about twice the width of the root ball and equal in depth. Carefully remove the tree from its container, disturbing the roots minimally, and place it in the center of the hole, ensuring the top of the root ball is level with the surrounding soil.

  4. Watering: After planting, water the tree thoroughly to eliminate air pockets. Regular watering is essential during the first few years, especially in dry conditions. Mulching around the base can help retain moisture and suppress weeds.

By following these steps, you can ensure that your Monkey Puzzle tree establishes well, providing a striking focal point in your garden for years to come.

Watering

Watering a Monkey Puzzle plant (Araucaria araucana) requires attention to its specific needs to promote healthy growth. This evergreen tree prefers well-draining soil, so it's essential to water it thoroughly but sparingly. The best strategy involves allowing the top inch or two of soil to dry out between watering sessions. Typically, watering every two to three weeks is adequate, depending on the season and climate.

During the growing season (spring and summer), increase watering frequency slightly, especially if the plant is exposed to higher temperatures or direct sunlight. In the fall and winter, reduce watering as the plant enters dormancy.

Always check for signs of overwatering, such as yellowing leaves or root rot, and ensure the pot has drainage holes if grown indoors. This balanced approach helps mimic the Monkey Puzzle plant's native habitat, ensuring it thrives in your garden or home.

Pruning

Pruning a Monkey Puzzle plant (Araucaria araucana) requires careful consideration due to its unique growth habit and structure. The best strategy is to conduct pruning during late winter or early spring, just before new growth begins. This timing minimizes stress on the plant and helps it recover more effectively.

When pruning, it’s essential to remove only dead, damaged, or diseased branches to maintain the plant's natural shape and health. If shaping is necessary, avoid cutting back into old wood, as Monkey Puzzle plants do not sprout new growth from old wood. Instead, cut just above a healthy leaf whorl to encourage a well-balanced appearance.

Use clean, sharp pruning shears to ensure clean cuts, which help prevent disease. Avoid aggressive pruning, as this can harm the plant’s majestic silhouette, and remember that moderate care will yield a thriving and beautiful centerpiece in your garden.

Weeding

Weeding around a Monkey Puzzle plant (Araucaria araucana) requires a careful approach to protect its unique structure and growth pattern. Start by assessing the area for weeds, particularly during the growing season when competition for nutrients is highest.

The best strategy is to use hand weeding, as this minimizes damage to the plant’s shallow roots. Wear gardening gloves to protect your hands from the plant’s sharp leaves. Gently pull weeds by their roots, ensuring you remove the entire root system to prevent regrowth.

Consider mulching around the base to suppress future weed growth while adding organic matter. An organic mulch, such as wood chips, can help retain soil moisture and cool the soil, benefiting the Monkey Puzzle. Regular checks during the growing season will keep weeds under control and promote a healthier growing environment for your Monkey Puzzle.

Mulching

When mulching a Monkey Puzzle plant (Araucaria araucana), it is essential to enhance soil moisture retention while also regulating soil temperature. Start by applying a layer of organic mulch, such as shredded bark, pine needles, or wood chips, around the base of the tree. Aim for a thickness of 3 to 4 inches, ensuring that the mulch does not touch the trunk to prevent rot.

It's best to mulch in early spring after any frost threat has passed, allowing the plant to benefit from the added nutrients as the mulch decomposes. Replenish the mulch layer annually to maintain its effectiveness. Besides moisture retention, mulching helps suppress weeds that could compete for nutrients. With proper mulching, the Monkey Puzzle tree can thrive, develop strong roots, and display its unique beauty for years to come.

Fertilizing

When fertilizing a Monkey Puzzle plant (Araucaria araucana), it's crucial to take a thoughtful approach. These ancient trees prefer well-drained soil that closely mimics their native environment of Chile and Argentina. The best strategy involves fertilizing during the growing season—spring and summer months.

Opt for a slow-release, balanced fertilizer with an N-P-K ratio of around 10-10-10. This ensures a steady supply of essential nutrients without overwhelming the plant. Apply fertilizer sparingly, typically once or twice during the growing season. It’s best to incorporate the granules into the soil around the base of the plant and water thoroughly after application.

Additionally, monitor the plant closely for any signs of nutrient deficiency, such as yellowing needles, and adjust your fertilization schedule accordingly. Over-fertilizing can harm the plant, so it's essential to prioritize quality over quantity.
