Tamarix — commonly called Tamarisk–are grown for their attractive, feathery foliage of small needle-like leaves and racemes of small pink or rose flowers. They are large shrubs and small trees that grow in windy locations, salt spray, and poor or sandy soil. They can be used as a windbreak, exposed hedge, and in seacoast gardens.
Tamarix can be invasive in mild-winter regions; they are less aggressive in chilly winter regions. They need regular pruning and can become top-heavy and unstable if not attended to.
Tamarix is a genus of more than 50 species of deciduous shrubs and small trees. Tamarix is native to coastal sites and dry or marshy areas from West Europe and the Mediterranean to East Asia and India.

Where to plant Tamarix
- Plant Tamarix in full sun.

When to plant Tamarix
- Set Tamarix in the garden in spring or autumn.
- Sow seed in a cold frame as soon as it is ripe.
Planting and spacing Tamarix
- Set bare-rooted Tamarix out in early spring and cut the tops back to about 6-12 inches (15.2-30.5cm) from the ground.
- Container-grown Tamarix can be set out at any time without cutting back.
- Balled-and-burlaped Tamarix, those with original soil ball wrapped in burlap, are not usually satisfactory because Tamarix do not have enough roots to hold the soil ball together.
How to water and feed Tamarix
- Give Tamarix moderate to very little water.
- Feed Tamarix with an all-purpose organic fertilizer in spring.
How to care for Tamarix
- Tamarix species—Krashgar, Odessa, and five-stamened tamarisks—should be pruned back severely in early spring before new growth starts, leaving only 2-3 inch (5.1-7.6cm) stubs of the previous season’s growth so that the current season’s growth can produce many stems and an abundance of flowers.
- Prune Tamarix regularly to maintain graceful effect.
Tamarix pests and diseases
- Tamarix is seldom bothered by pests or diseases.
Tamarix propagation
- New Tamarix plants can be started from softwood cuttings of young growth in late spring or early summer, from semihardwood cuttings of more mature growth in mid- or late summer, or from hardwood cuttings of dormant leafless growth in late fall or early winter.
