Lespedeza, crown vetch, clover, sweetpea and all legumes are great for road sides. They add about a pound of nitrogen per year. To keep it thick and healthy, you don't need to fertilize (except P and K, and lespedeza doesn't need much P, and acid soil is OK). Why would you want to get rid of it? Better you should try to spray to get rid of dandelions and thistles--and leave the lespedza alone. Can you mow once per year just before greenup? This might be a good place to apply manure waste.

the lespedeza is growing thick and tall and falling over, it looks unkept. the POA wants something done about it. alot of the terrain is steep and it is not possible to mow. we keep about 3 to 4 feet mowed along the road and the lespedeza has taken off and is hanging everywhere. i dont want to kill it all, but maybe peel it back 2 or 3 ft. i need something selective because i want to keep the grass for sroision control......

Milestone or Garlon4. That will kill anything that is not a grass. Weed-B-Gon might work partially, but I have had bad experiences with amine based Three-Way herbicides.

If you just want to set it back triplett or three way will do. If you need more try crossbow or something with Chlorypid. Not sure I got that spelling right.

Not being familiar Lespedeza I didn't want to answer. But in Aquatic work where I don't want to kill a steep bank because of erosion control, but still want knock down height. I use Diquat (Reward) as a non systemic contact kill and spray lightly (depending on height) over the top. This seems to knock back or suppress height with out actually killing the ground cover.
