In 1948-49 studies were made on the spreading of multiflora rose at the sites of three old plantings in Alabama and Georgia. The age of these plantings varied from 14-40 years. Roses were invading surrounding land at each site. Observations indicated that seeds are carried by water and birds. Seedlings were numerous in drainageways leading from old shrubs. Birds had deposited seed under trees, in thickets, and along hedgerows. Seedlings growing under a single tree varied in number from a few to 50. Two rose bushes were found under a tree a mile from the probable point of origin. Seedlings were spreading in unimproved pastures by growing in thickets where they were protected from grazing and mowing. Plants were not found in cultivated fields. Spreading was similar near all three locations in like plant communities. Competition from trees affected multiflora more than that of any other type of vegetation. Plants thrive in pine woodlands with an open canopy, but growth is weak in a thick hardwood stand. Control will be necessary if multiflora rose is to be kept from spreading in idle land and unimproved pastures.
