Hardy, tough, and fast-growing, this small to medium-sized deciduous tree from northern and central Asia was once a popular choice for difficult sites. It is much less frequently used today because of its undistinguished appearance, weak wood, and weedy nature. Of variable habit, it bears small, oval, dark green leaves on upright to spreading branches. The disease-resistant leaves persist late into fall, dropping while still green. Inconspicuous early spring flowers are quickly followed by masses of round papery seeds, which scatter and germinate over a wide area. This tree is notorious for losing branches to wind and winter precipitation.
This sun-loving tree grows well in most soils and tolerates high pH, bitter cold, and moderate to severe drought. It is also resistant to Dutch elm disease. It makes a good choice for areas with climates too harsh for most other trees. It can also be used for bonsai. It is listed as an invasive plant in many regions. (source: learn2grow.com)

|1. Soak overnight in warm water.
2. Fill an oblong container or planting tray with a soil that drains well and does not hold water. Use a container that drains from its bottom. The seeds will rot and not germinate if planted in heavy soils or containers that remain saturated.
3. Place the seeds on top of the container's soil, spacing them out from each other. Cover the elm seeds with a 1/4-inch layer of soil, pressing it down with your hand to firm it up.
4. Water the container after planting. Thoroughly saturate the soil until water runs from the bottom drain holes. Keep the soil moist, but not wet while the Ulmus parvifolia seeds germinate, in approximately one week.
5. Situate the container in a greenhouse or warm, bright area. Keep the seeds and seedlings protected in the warm area throughout winter.
6. Remove the Ulmus parvifolia seedlings and divide them when they are approximately 4 to 6 inches tall. Plant each seedling into its own container, as they are more difficult to transplant after they grow too tall.
