Abstract

Rhizome sections of ironweed from which the fleshy roots had been pruned made less than half as much growth in the greenhouse as sections which had three inches of fleshy roots attached. Rhizome sections at least two inches long with portions of the fleshy roots intact should be used for asexual reproduction of ironweed. Ironweed plants in the field after 8 and 9 years of mowing treatments at 2 dates were approximately ⅔ as tall as untreated plants. No significant reduction in stand was obtained by 9 successive years of mowing.
