Monkey Puzzle Tree
(Araucaria araucana)

The Monkey Puzzle Tree is an odd looking evergreen tree worthy for novelty purposes. Best adapted for the West Coast, the Monkey Puzzle Tree can reach heights of 50 to 80 feet. The Monkey Puzzle is a slow-growing tree. It can take 5 to 10 years for a Monkey Puzzle tree to grow only a few feet tall.  

Growth Rate: Slow

Soil Type: Prefers warm and moist soils.

Zones: 7 to 11

Germination Range: 30-50%

Stratification Requirement: Seeds do not require pre-treatment. We recommend soaking in 24 hours before planting. The Monkey Puzzle is a very slow-growing tree. Seeds can take 2-4 months to germinate.

Indoor Planting: If your seeds require stratification or scarification – do the recommended pretreatment before planting indoors. Planting Instructions: Fill a container with seed starting mix to about ½ inch from the top. Place your seeds 1 inch to 1 ½ inches below the soil surface. Gently water your seeds to keep moist, not soaking wet. Heat & humidity is critical for germination. Germination may occur in 1 week or as long as 3 months (depending on the species). Place the seed container on a heat mat under growing light(s). Keep your growing lights on 14 hours per day. Keep your heat mat on 24 hours per day. Once your seeds germinate, move each seed into its own container under the growing lights and on the heat mat. Keep your seedlings indoors for 2-3 months before transplanting outdoors in the spring (May to June).

Outdoor Planting: If your seeds do not require stratification: the best time to plant tree and shrub seeds outdoors is after the last frost in your area (spring). In the Northern states – the best time to plant seeds outdoors is from May to June. If your seeds require pretreatment: you should plant your seeds outdoors before the ground freezes in your area (late September to early November). Your seeds will naturally stratify during the cold winter. Germination usually occurs in May or during the spring season.
