Monkey Puzzle Tree Care

Climate

If you live in a cold region, it’s not advisable to grow a monkey puzzle tree outdoors. You must keep the plant indoors in a large pot as part of your home interior. This tree thrives in temperate climates where it can receive cool or moderate temperatures with abundant rainfall.

To keep monkey puzzles happy and healthy, always ensure the temperatures don’t fall to below 5 degrees fahrenheit and don’t exceed 50 degrees fahrenheit. These trees grow best in cool and humid regions, even during summer. They don’t tolerate drought or very hot conditions just as they won’t withstand frost.

Light

Monkey Puzzle Tree Light

Monkey puzzle trees prefer partial shade or full sun, with around 3-6 hours of sunlight a day. If your region has hot summers, plant the tree in a partial shade area. The key is to pick the right location in terms of sunlight and shade, especially if you live in a hot area.

Soil and Water

Monkey Puzzle Tree Soil and Water

Any type of soil is suitable for a monkey puzzle, provided it is well-drained. Clay soils tend to remain soggy for longer so it’s not advisable to use them for growing monkey puzzles. Having said that, you can always add some fine sand to the clay soil at the planting time in order to increase drainage. These trees prefer adequate moisture, especially when they are newly planted and young.

Water your monkey puzzle deeply every week during its first year to boost growth. To maximize moisture in the soil, add 2-3 inches of thick mulch layer at the tree’s root zone.

Fertilizer

If the soil isn’t fertile, you can amend it by adding a fertilizer every month from early spring to fall. Use water-soluble, all-purpose fertilizer by mixing half a teaspoon of the product in a gallon of water. Keep in mind that overfertilizing your monkey puzzle can damage its roots so always follow the fertilizer’s application instructions and only feed the tree once a month during the growing seasons.

Propagating Monkey Puzzle Tree from Seeds

The 6-inch long cones of monkey puzzles can take several years to mature. Once the cones are developed, they release their 1.5 inch-long seeds. It is these nut-like seeds that can be propagated and grown into a new tree.

The seeds germinate best when they are sown within 1 month after collection. Soak the seeds in mineral water for 2 days before planting them in a small container filled with moist sand. Place this container in the fridge for two weeks to keep them chilled. They will be ready for sowing after this period.

Now your seeds are ready to be sown in a 1-gallon pot filled with half perlite and compost. Keep the sown seeds indoors near the window where they can receive bright sunlight. The seeds must be kept warm at minimum temperatures of 70 degrees fahrenheit. Keep the soil moist and within 10-30 days, you should see seedlings sprouting from the soil.

Growing Monkey Puzzle Tree Indoors

One of the biggest advantages of growing monkey puzzles indoors is their very slow-growing quality as you won’t need to repot these trees regularly. In fact, you can keep the tree in its original pot for several years before planting it in the ground. In colder climates, you will need to keep the potted tree indoors or in a greenhouse.

When choosing a container for your monkey puzzle, pick a broad and deep pot with good drainage. The container must have several drainage holes at the base. Use fast-draining soil that’s enhanced with pumice or perlite for balanced moisture. You can amend the potting soil by adding 1.5 teaspoons of 20% phosphate with 1 tablespoon of limestone and 2 teaspoons of fertilizer (5-10-5 formula) to support the plant’s nutritional needs.

Remember to place the potted monkey puzzle in a warm, sunny location where it can get up to 6 hours of sunshine daily. To prevent the tree from dehydration, mist the leaves often and water the soil whenever it feels dry just beneath the soil’s surface.

Planting Monkey Puzzle Tree in Ground

So you’ve decided to plant your pot-grown monkey puzzle tree outside, but wondering how to do it. Follow these step-by-step instructions and you’ll soon be enjoying your landscape with this unique tree.

Step 1. Wear a pair of gardening gloves to protect your hands as the triangular leaves of this tree are very sharp.

Step 2. Dig a hole using a shovel. Make sure the hole is the same depth as the plant’s container but twice the width.

Step 3. Take the tree out of its container by placing the pot on its side on the ground and tapping the four sides with your palm. Pull the container gently off the roots and if the tree is root-bound, untie the roots to free them from the pot’s drainage holes.

Step 4. Plant the tree in the center of the dug up hole. Loosen the roots and spread them out with your fingers to prevent root bound.

Step 5. Add more garden soil to the hole to keep the tree securely in place. Create a watering basin of about 3 inches deep and fill it with mulch to retain moisture in the soil.

Step 6. To keep the newly planted tree well watered, irrigate it using a garden hose. Make sure the hose is set on a low flow setting and keep the soil moist to a depth of one inch during the first growing season.

Caution: when you’re planting the tree in the hole, refrain from stamping the soil down as this can damage the roots or prevent them from growing.

Best growing Location

When planting a young monkey puzzle in the ground, make sure you choose a location that either receives partial shade or full sun. In sites with intense hot summers, a little afternoon shade will protect your young tree from heat stress.

Monkey puzzles prefer humid locations and do well in a salty air environment. This means they will thrive in coastal areas, but not in cities as they don’t like pollution. If you live in the city and still want to grow these trees, you can keep them in containers in the balcony and move them indoors during winter to protect the trees from sub-zero temperatures.

Monkey Puzzle Tree Growing Problems

Monkey Puzzle Tree Growing

Although the monkey puzzle tree is easy to grow in the right conditions, when grown in soggy soil, it becomes prone to fungal disease, canker, and pests including spider mites, thrips, and mealybugs. These insects can cause foliage browning, but they can be controlled using insecticide sprays that are diluted with water. To prevent fungal diseases, make sure the tree is planted in well-drained soil.
