Quick facts

About Andean walnut

The Neotropical Walnut (Juglans neotropica) is a majestic tree native to the Andean regions of South America, renowned for its high-quality timber and edible nuts. It features a straight trunk and a dense canopy that provides ample shade, making it ideal for parks, large gardens, or estates where its stature and fruits are valued. Its deciduous foliage enriches the landscape with autumnal hues before leaf drop.

Native range

South America, from Colombia to northern Argentina and Chile

Care tips

It requires full sun exposure for optimal development and good nut production, at least 6 hours daily. Watering should be regular during the first few years and in dry periods, ensuring good drainage to prevent waterlogging. It prefers deep, fertile, and well-drained soils, with a neutral to slightly acidic pH. A common mistake is planting it in shallow or compacted soils, which limits its root and overall growth.
