|Germination||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.
