Mediterranean saltbush
Atriplex halimus
A bulletproof saltbush for the harshest dry and saline edges — fast cover, livestock fodder and chop-and-drop where little else survives, but it can spread if left unchecked.
Mediterranean saltbush in a syntropic line
Mediterranean saltbush belongs in the Shrub layer as a Secondary biomass species. Support species, fruit, and nitrogen fixers under the canopy. Rough in-row spacing starts around 1 m in a syntropic row. Good line partners include Carob tree, Common sage. As a Secondary species it carries mid-term yield and structure while climax trees slowly claim the canopy.

How to manage it
Salt- and drought-tolerant pioneer shrub for coastal and alkaline ground; cut hard for fodder or mulch to keep it dense and productive.
How to propagate
Sow seed in spring or take softwood cuttings in summer — both establish fast.
Guidance, not a guarantee — success varies by species and skill.
What to watch out for
Not a nitrogen fixer. Naturalises readily on disturbed saline ground and can become weedy; leaves are salty, so limit as sole livestock fodder.
Frequently asked questions about Mediterranean saltbush
Is mediterranean saltbush frost-hardy?
Yes for winter cold in many climates — generally hardy to around -10°C when dormant, with medium frost tolerance in the catalog. Flowering crops can still lose a season to late frost, so site them carefully.
What soil does mediterranean saltbush need?
It does best on sandy, rocky ground, at pH about 7–8.5.
How much water does mediterranean saltbush need?
Plan for a rainfall floor around 200 mm/year, plus low irrigation once established.
Can mediterranean saltbush handle wet or waterlogged soil?
Poorly — mediterranean saltbush has low waterlogging tolerance, so keep it off winter-wet clay and standing water.
What should I watch out for with mediterranean saltbush?
Not a nitrogen fixer. Naturalises readily on disturbed saline ground and can become weedy; leaves are salty, so limit as sole livestock fodder.
