Pesky Broadleaf Weeds Flowering in Turf
The trifecta of common trifoliate broadleaf weeds Black medic (Medicago lupulina), white clover (Trifolium repens) and yellow woodsorrel (Oxalis stricta) are all currently flowering and infesting turf. Black medic and white clover are commonly found growing on low fertility, low maintenance sites such as roadsides, boulevards, neglected home lawns and, in some cases, golf course rough. Black medic and clover are very competitive in low fertility sites because they host rhizobacteria that fix atmospheric nitrogen into plant available nitrogen.

The frequent rains this year have not only resulted in mowing challenges, but have also resulted in some turf areas in need of nutrition. Not surprisingly, Michigan State University Extension has received reports of red thread (Laetisaria fuciformison) on lawns and landscape turf areas for several weeks now.
It seems that every year we observe red thread on lawns or golf course roughs and often the outbreak follows the seedhead production period when the plant is probably looking for a little extra nutrition. The common lawn mix turfgrasses Kentucky bluegrass, perennial ryegrass and fine fescue are all susceptible, with perennial ryegrass being particularly susceptible.
