Common lespedeza, also known as Japanese clover or annual lespedeza, has three smooth, oblong leaflets with parallel veins that are nearly perpendicular to the midvein (Figure 1). Early spring aerification may predispose lawns to summer annual weed establishment since the grasses are not able to fill in voids in a timely manner. UGA Extension offers a wealth of personalized services Some studies have indicated that the consumption of sericea lespedeza by livestock could help control and reduce gastrointestinal parasite egg counts (chemical anthelmintics properties), reduce methane gas emission (due to tannin concentrations), and improve protein and amino acid utilization in ruminants. Examples of three-way herbicides are: Note: Herbicides containing 2,4-D should be applied at a reduced rate on St. Augustinegrass and centipedegrass to prevent damage to these lawns. Lespedeza prefers areas with dry, underfertilized, compacted soils and is often an indicator of low nitrogen levels in the soil. Subscribe to receive top agriculture news, Be informed daily with these free e-newsletters. (Optional) It is best to use a no-till drill. The severity of grazing the companion grass will influence the rates at which nitrogen can be applied safely. Manage annual lespedeza in the fall for forage during the summer slump. The three cultivars of Korean are Climax, Harbin, and Rowan. How to Grow Lespedeza - Bush Clover - Garden Chronicle Seeds are produced where the leaves join the main stem and have a blotched color. Missouri farmers ordinarily can produce 1 to 2 tons of lespedeza per acre depending on variations in weather and management. Shortly after World War II, farmers started using more fertilizer on small grains, especially heavier rates of N. This increase brought about higher production of small grains, but the increased competition severely reduced lespedeza production. It produces from June through October.

Noteworthy Characteristics. Granular products may also be applied to non-irrigated sites for better soil incorporation than liquid formulations. For tall fescue, aerficiation should be timed in early fall, once the grass has recovered from summer stresses. The stems are wiry. Lespedeza acreage in Missouri reached its peak in the early 1950s, then started to decline. Striate lespedezas (common, Kobe) reseed dependably only when grown in the southern one-third of Missouri because of the longer growing season. Applications of K usually give a marked response after the soil has been limed and phosphated.

Proper management, plus some summer rain, will allow lespedeza to produce quality pasture during midsummer when companion cool-season grasses are of low quality and not very productive. Dry matter yields of lespedeza are lower than alfalfa or clover when grown under favorable growing conditions. Crude protein ranges from 12 to 15 percent. Lespedeza striata) is a freely branched, summer annual legume that is a problematic weed in lawns and other turf areas. This Extension factsheet can also be viewed at: N.C. Preemergence herbicide applications on non-irrigated sites have less potential for residual lespedeza control compared to irrigated turf from product loss, poor soil incorporation, and lack of herbicide activation by rainfall or irrigation. Leaves are trifoliate, club or wedge-shaped, and attached by short petioles. Lespedeza can be rotated with small grains if N applications do not exceed 20 to 30 pounds per acre. Dry conditions may reduce growth, but the plants recover quickly following summer rains. The two species of annual lespedeza grown in Missouri are Kummerowia striata (common) and Kummerowia stipulacea (Korean). Phosphorus fertilization increases annual lespedeza forage and seed yields. While annual lespedeza has tannins, they are at moderate to low levels, Roberts explains. Schind syn. (2004). During this same time, bacterial wilt, tar spot and other plant diseases were becoming a more serious problem on Korean lespedeza.
