# Alternative Names

Chinese elm, dwarf elm, Asiatic elm

# Uses

*Ethnobotanic*: The dried inner bark was grounded into a powder and used
as a thickener in soups or added to cereal flours when making bread. The
immature fruit was used to produce a sauce and a wine (Facciola 1990).
The hardy, heavy tough wood was used for agricultural implements and
boat making (Vines 1987).

*Agroforestry*: *Ulmus pumila* is used in tree strips for windbreaks.
They are planted and managed to protect livestock, enhance production,
and control soil erosion. Windbreaks can help communities with harsh
winter conditions better handle the impact of winter storms and reduce
home heating and cooling costs.

# Status

# Considered a noxious weed in New Mexico. Please consult the Plants Web site and your State Department of Natural Resources for this plant's current status, such as, state noxious status and wetland indicator values.

# Description

*General*: Elm Family (Ulmaceae). Siberian elm (*Ulmus pumila*) is an
introduced, fast-growing, small tree, five to ten meters high. The
leaves are alternate, simple, elliptic to oblong-lanceolate, usually
simple serrate and 2.54 to 8 cm long. The flowers are greenish,
clustered, short pediceled and appear with or before the leaves from
March through April (Vines 1960). The bark is light grayish-brown,
irregularly furrowed, and often streaked with stains caused by bacterial
wetwood. The fruit is a long and broad samara, appearing from March
through April, composed of a central, dry, compressed nutlet surrounded
by a thin wing. (Ibid.).

*Distribution*: Siberian elm is a fast-growing tree that was introduced
to the United States in the 1860\'s. Native to northern China, eastern
Siberia, Manchuria, and Korea. It is the hardest of all elms and does
well even in areas with cold winters and long periods of summer
droughts. Because this, elm tolerates a variety of conditions such as
poor soils and low moisture, it is found in dry regions, along
roadsides,

in pastures and grasslands. For current distribution, please consult the
Plant profile page for this species on the PLANTS Web site.

# 

# Adaptation

*Ulmus pumila* is easily grown in any well-drained soil type but prefers
well-drained fertile soil. This species prefers full sun and succeeds
well in arid regions. The tree also grows in moist soils along streams.
It invades dry and mesic prairies, including sand prairies, drought
resistant and fairly wind tolerant.

# Establishment

*Propagation by Seed*: Siberian elm seeds should be sown as soon as ripe
in a cold frame. Excessive drying and dewinging should be avoided as
they reduce viability (Dirr & Heuser 1987). Twelve to twenty seeds are
sown per linear feet in drills ten inches apart and covered ¼ inch with
firmed soil. The seedbeds should be kept moist, but not particularly
shaded. When the seedlings are large enough to handle, place them into
individual pots and grow them in the greenhouse for the first winter.
Plant them into their permanent positions in late spring or early summer
of the following year.

# Management

Siberian elm has been planted in the Upper Midwest in shelterbelts and
as a shade trees along boulevards and in parks (Rosendahl 1955). Some of
the plantings have proved successful while others have not, because the
seeds were derived from climatically different areas of the species
geographical range, which varies in the level of winter hardiness
(Ibid.).

Siberian elm seeds with three to eight percent moisture can be stored at
36 to 40ºF in sealed containers for eight years (Dirr & Heuser 1987).
Seedlings should not be allowed to grow in a nursery bed for more than
two years because the plant will develop a taproot that make lifting
harder and reduces outplanting survival rates.
