Pre-treatment: Mechanical scarification for 15 seconds using a Forsberg seed scarifier, hot-water soak prior to greenhouse planting, or soaking in concentrated sulfuric acid (H2SO4) for 30 minutes then rinsed thoroughly under fresh water.
Establishment: Rhus copallinum, also known as Winged Sumac, Flameleaf Sumac, or Shining Sumac, is found in various locations throughout the US, particularly in dry woods and clearings. It tolerates dry, sandy, and acidic conditions but thrives on moist sites. The plant is distributed throughout all Eastern and Central states with the exception of Minnesota, North Dakota and South Dakota. Some protocols do not require pre-treatment.
