Elm trees were once abundant throughout most of the eastern United States. In the middle of the 20th century, Dutch elm disease, a fungus, nearly wiped out all the elm trees in the country. As a result, there are few specimens in America left that are completely healthy and in full maturity. You can help preserve these trees by planting elm seeds. Once you have established seedlings, you can plant them out of doors.
Things You'll Need
Clay
Charcoal, peat
Potting soil
Pebbles
Gardening pot
Water
Elm seeds
Prepare a mixture of clay, charcoal, peat, potting soil and pebbles. Elm trees grow best in soil that drains well. Soil pH can range anywhere from 5.5 to 8.
Fill a medium-sized pot three-quarters of the way up with the soil mixture.
Insert the elm seed into the potting soil, wing side up. Cover the seed with soil only to the point where the seed meets the wing. There is no need to plant the seed deeper, as elm seeds rarely are able to penetrate completely into the soil and will propagate in nature without full immersion.
Water the seed and place it in full sun. Keep the soil moist--but not saturated--until the seed germinates. This should take one to two weeks but can take up to two months, according to the U.S. Department of Agriculture Forest Service.
Tips & Warnings
If you collect or purchase your seeds in the spring, you should be able to plant your seeds right away with no treatment. If you get your seeds in the fall, you may need to cold stratify (chill) the seeds for two to three months before you plant them. This will trick the seed into thinking it has gone through the winter.
