Description

Soapbark Tree (Quillaja saponaria) is a tree native to higher elevations in Chile. It is a large tree that matures 45’-65' tall and 15’-25’ wide, with a similar texture and overall shape to many California native Oak trees. It can have a very regular upright shape if it has a single trunk, but the multi-trunks tend to be more irregular. A licensed arborist should be hired to maintain this tree as it matures. This tree should be planted at least six feet away from any hardscape areas, 15 feet from structures such as houses and buildings, and not near any powerlines. Shrubs and perennials should be planted about four feet away from this tree. It should be irrigated for about 45 minutes once a week when using most in-line drip irrigation systems.
