Moderate watering is required, and the plant has an average drought tolerance. The soil should have a pH of 5 or up to 8. It can grow in chalk, clay, loam, sand, peat, or combinations.

As noted by Carl Johnson in Ambio, "Exposures of a large population in the Denver area to plutonium and other radionuclides in the exhaust plumes from the plant date back to 1953." Weapons production at the plant was halted after a combined FBI and EPA raid in 1989 and years of protests.
