Germination Information

Pre-treatment: Sow seed in nursery beds within one month of harvest as it does not maintain its germination in storage.

Establishment: Smooth alder is native to the eastern United States in USDA plant hardiness zones 5 through 8. It grows best in wet bottomlands and stream margins as well as in moist, well drained upland areas. It is moderately shade tolerant, but is weak-wooded and susceptible to wind and ice damage. It is not adapted to alkaline, saline, droughty, or extremely acid soils. Use of 'Panbowl' is recommended only in specific USDA Major Land Resource Areas where it was tested.
