Any successful multiflora rose control program requires some yearly retreatment or proper grazing management. Unless the landowner is willing to adopt a long-range program, any success achieved in one year will be largely negated by reinfestation in two or three years.
Dead shrubs should be removed by the next season. Incompletely killed plants should be either spot treated with appropriate herbicide or mechanically removed. Rotary mowing is an effective way to rid a pasture of smaller to moderately sized dead shrubs. Rotary mowing shatters and scatters the brittle topgrowth to hasten decomposition. Size of equipment will determine maximum size of plants that can be removed by mowing. Extremely large shrubs with 6- to 8-inch diameter basal crowns often may have to be removed by a bulldozer, front end loader, or tractor and chain. Burning removes dead top-growth in a hedgerow or piled dead plants from a pasture rapidly, provided it can be done safely and in conformity to local burning ordinances.

If possible, relocate fencing so the previously infested area can be reseeded and mowed regularly. If this is not possible, reseed and be prepared to remove any new shrubs that develop near the new fence chemically or mechanically (Figures 19 and 20).
Within pastures, remove any rolls of old fencing, abandoned equipment, or piles of junk that may shelter rose plants so the maximum area can be mowed periodically. Continue to retreat escapes or newly emerged seedling plants once or more annually, or use goats/sheep for control in steeper pastures where mowing is not possible. Similarly, use herbicide or mechanical removal to control new seedlings that appear in wooded or semi-wooded non-crop areas.
