Argentine Savory Plant Care

Geoffroea decorticans (Gillies ex Hook. & Arn.) Burkart

Updated · Sources · How we source care data

Geoffroea decorticans, the chañar, kumbaru, or Chilean palo verde (green wood), is a small deciduous tree, up to 8 meters (25 ft) tall that inhabits most arid forests (montes or espinales) of southern South America. The chañar is cold and drought deciduous; it loses its leaves in winter, and possibly in summer if conditions get too dry. It is natural to Bolivia, Chile, Argentina, also present in Paraguay and southern Peru. It is a very characteristic tree in local culture and folk because of its vivid visual presence, propagation, and ancient ethnomedical uses.

What Soil Mix Works Best for a Argentine Savory?

Well-draining sandy loam with added organic matter. Good drainage is essential for Argentine Savory to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Argentine Savory?

Feed Argentine Savory every 8 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Where Should You Plant a Argentine Savory?

Choose a spot with full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Argentine Savory is suited to USDA Zone 12a.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

How Far Apart Should You Plant a Argentine Savory?

Argentine Savory can spread to about 15 ft (4.6 m) and reach about 20 ft (6 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Argentine Savory?

Prune Argentine Savory while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.
