Common Lespedeza
Lespedeza striata

Identification tips
This prostrate free-branched summer annual is a problematic weed in lawns. The leaves are trifoliate with lance-shaped stipules and hairs along the leaf margins. Small, single, purplish flowers grow from the leaf axils on most of the nodes on the main stems. Commonly found in soils with low fertility, it grows close to the ground in thin turf and dry, compacted areas.

One of the best control options for this summer annual is to keep it from germinating. In spring, apply a preemergence herbicide – such as Dimension® specialty herbicide – labeled for control of common lespedeza. A product containing dithiopyr will provide excellent control of many broadleaf weeds while controlling grassy weeds. If turf is thin or compacted, aerate the soil, raise mowing height, and keep the soil’s pH and fertility within appropriate levels for your turf.

Avoid the Pain of Poison Ivy

Poison ivy is one of many environmental hazards lawn care professionals face each day, but it shouldn’t be disregarded. According to the American Academy of Dermatology, about 85% of the population is allergic to the toxins in the plant. Because poison ivy grows almost everywhere in the United States, this weed can be a serious issue. Learn how to control poison ivy and protect yourself, your crew and your customers from the painful, itchy rash.
Safety First — Make PPE a Priority

PPE, or personal protective equipment, used to be an acronym that was not commonly heard in everyday circles. That’s not the case anymore. The coronavirus crisis has cemented the term and its vital importance into everyone’s lexicon. Clearly, PPE is extremely important in health care, but it is equally important in our industry too. Not only does it keep workers safe, but it is also the law. Let’s review the most common PPE requirements for lawn care operators.
